G 500

W463M113 5.0 V83 LOCKING DIFFSGRAZ, AUSTRIA

“A Cold War military design with leather, a V8 and three locking differentials. Lock all three at least once, if only to justify owning it.”

PART 01

Overview

Where it came from, why it matters, and how it changed year to year.

The story

The G 500 is what happens when a military truck is asked to wear a suit and refuses to take its boots off. It was the first V8 G-Class built in regular production, the first one most Americans could buy from a Mercedes dealer, and — underneath the wood and leather — the same ladder-framed, triple-locked machine that armies bought by the thousand.

A SHAH, AN ARMY AND A FACTORY IN GRAZ

The name goes back to Daimler-Benz’s six-wheeled G1 of 1926 — a Geländewagen, or cross-country vehicle — but the modern truck began in the early 1970s, when the Shah of Iran, then one of Mercedes-Benz’s largest shareholders, pre-ordered some 20,000 military vehicles. Mercedes engineered it; Austria’s Steyr-Daimler-Puch would build it in Graz. Design studies were carved in wood from 1973, and production began in 1979 — the same year the Shah fled Iran and his order evaporated.

It found other customers fast: border police, the Argentinian army and, in 1980, Pope John Paul II, who got one with a clear viewing platform. In 1983 a 280 GE driven by Jacky Ickx won the Paris–Dakar Rally, which settled any argument about whether it was a real off-roader.

THE W463 GOES UPMARKET

In 1990 the civilian G was reworked as the W463: a nicer cabin, full-time four-wheel drive and three fully locking differentials, while the utilitarian W460 and later W461 carried on separately. America still couldn’t buy one officially. New Mexico importer Europa International converted European trucks to US spec — later persuading Mercedes to build them to DOT standards — and some sold for as much as $135,000.

The G 500 arrived in 1998 as the first regular-production V8 G — the hand-picked, limited-run 500 GE of 1993 had come first — with the 5.0-litre M113, good for 292 hp. When Mercedes finally launched the G officially in the US for the 2002 model year, the G 500 and G 55 AMG were the two trucks in the showroom. The G 500 ran in America through 2008; for 2009 the same truck returned as the G 550 with a 5.5-litre V8. The seven-speed automatic had already replaced the old five-speed in US G 500s during 2007.

SIDEBAR · THE EUROPA TRUCKS

America’s G-Class before Mercedes sold one

Before 2002, the way to buy a new G in the US was Europa International of Santa Fe, New Mexico. Europa did the expensive work of federalizing European trucks, became the exclusive US importer with Small Volume Manufacturer status, and sold 300 GEs, G 320s and early G 500s, federalized and certified for US sale — 50-state legal, not gray-market. In 2002 Mercedes-Benz bought the US distribution rights and Europa turned to service, parts and the models America still never got, like the three-door Cabriolet.

A Europa G 500 looks like a 2002 truck from outside. Inside it’s simpler: a steering wheel and gauge cluster from the pre-facelift W210 E-Class (yes, the sedan), no factory radio controls on the wheel, and a 5-speed automatic without the later tip-shift gate. Some enthusiasts prefer them for exactly that: German Cars For Sale Blog quotes a seller who steers buyers away from the electrically troubled 2002–05 MB-USA trucks and towards Europa Gs.

Specs & capability

How it’s built, what it can do, and what fits under it.

How it’s built

Strip the G 500 down and you find a 1970s off-roader that was never diluted. The body sits on a separate ladder frame. Both axles are solid, located by links and sprung on coils, so a twisted trail keeps the tires planted. Power goes through a two-speed transfer case to all four wheels all the time, and the three differential locks — centre, rear, front — let you turn it into something closer to a tractor when traction runs out.

CHASSISLadder frameSeparate steel frame under the body — the reason Gs survive decades of abuse.
AXLESSolid, front & rearCoil-sprung and link-located. Independent front suspension only arrived with the 2018 redesign.
DRIVETRAINFull-time 4WDTwo-speed transfer case with low range.
LOCKERSCentre, rear, frontThree 100% locks, engaged from the dash.
ENGINEM113 5.0 L V8292 hp, 456 Nm. Shared with the era’s E-, S- and ML-Class — parts are plentiful.
GEOMETRY36° / 31°Approach and departure angles quoted by Hagerty for the G; Mercedes' 2015 G 550 manual lists 34° / 29°. Track: 56 inches.
USING THE LOCKERS

Lock the centre first, then the rear, then the front — and only on loose surfaces at walking pace. Unlock in reverse once you’re through. On owners’ reports from mid-2000s trucks, the centre lock is vacuum-operated while the axle locks are hydraulic, which is why a single split vacuum fitting can take out the whole sequence (see repairs below).

Stock275/70R18 (≈33 in)Fits an unlifted G 500 on factory 18s per Expedition Portal owners; a 285/65R18 rubs slightly at full left lock, and an ET63 aftermarket wheel rubbed where ET43 G 550 wheels didn't. Re-code the tire size so the speedo and ESP agree.
2–2.5 in33x11.00–33x12.50 (or metric equivalent)JWO 2-in and Eurowise 60 mm springs are sold as 33-in setups; JWO says keep wheel offset at +30 or lower (about a 30 mm spacer on most stock wheels) and fit longer shocks.

4 in35x11.00–35x12.50JWO 4-in springs: offset no higher than +20 (typically a 50 mm spacer on stock wheels), caster-correction bushings required; adjustable panhard bars and a steering stabilizer recommended. Distronic likely won't work at this height.

Forum consensus, not a guarantee: wheel offset, tire brand and suspension wear all change clearance. Confirm before you buy.

Production & special editions

The G 500 was a regular-production model, so it's the special editions that carry the numbers.

Buying one

What to pay, what to check, and how to tell a good one from a clone.

What they cost

On Bring a Trailer, prices have barely moved since 2018: the 2002–2008 G 500 is the cheapest way into a V8 W463, so condition and records matter far more than the year.

Project / high mileage / needs work$18k–25k
Driver$25k–45k
Excellent / low mileage$50k–80k+
G 500 Cabriolet (Euro / Europa)$175k–275k

Based on 55 sold Bring a Trailer auctions of 2002–2008 US-market G 500 wagons from January 2025 to October 2026 ($18,500–$80,500, median about $35,000), plus four G 500 Cabriolet sales from 2024–26. Documented low-mileage trucks sit at the top; 2005 Grand Editions have sold for $34,500–44,200 in that period. Prices move; checked October 2026. See live listings below.

What to check before you buy

  1. 01
    Test all three locking differentialsEngage each lock on a loose surface and watch the indicators. Lockers that ‘were never used’ by the last owner often don’t work — budget for the vacuum diagnosis below.
  2. 02
    Is it really an AMG?Plenty of standard Gs have been dressed as AMGs. Check the VIN and data card against the badges before paying an AMG premium.
  3. 03
    Listen at idleVibration or a chirp that changes with revs on an M113 points at the harmonic balancer — a known failure on early-2000s Mercedes V8s.
  4. 04
    Look for oil on top of the engineWetness at the front of the V points at the oil filter housing seals; oil on the coil packs and exhaust manifolds points at valve cover gaskets or breather hoses. Neither is serious if fixed early, and both are reasonable DIY jobs (see repairs).
  5. 05
    Look behind the front wheelsGear oil on the inside of the wheels or the brake calipers means leaking front axle seals — and possibly contaminated brakes.
  6. 06
    Drive it at 55–70 mphWander or steering shake at highway speed usually means a tired steering damper and worn linkage.
  7. 07
    Rust where nobody cleansCheck the tailgate’s lower edge, door bottoms, sills, rear frame tubes, inner wheel arches and around the rear bumper.
  8. 08
    A sagging headliner means waterUsually blocked sunroof drains. Water can reach the fuse box and climate actuators, so check those too.

Spotting the real thing

G 500s get dressed up as AMGs, and the early trucks came through three different doors — Europa International, grey imports and Mercedes-Benz USA — so check the paperwork, not the badges.

  1. ID
    US VINMercedes-Benz USA G 500s (2002–2008) start WDCYR49E; NHTSA's decoder reads that as a G-Class with a 5.0-litre engine built in Graz. Position 10 is the model year and position 11 is X for the Graz plant. A 2003 G 55 AMG reads WDCYR46E instead.
  2. ID
    Europa trucks1998–2001 trucks sold by Europa International carry US VINs issued by Europa, not Mercedes. NHTSA's decoder flags one BaT-sold 2001 G 500 Europa VIN (WDBEG4213Z7122501) as non-standard, so expect the import paperwork to tell the story.
  3. ID
    Fake AMGsBumpers, flares, wheels and badges bolt straight on, and Autocar warns about Gs converted to look like AMGs. Check that the VIN and factory data card agree with what's on the tailgate.
  4. ID
    Factory data cardMercedes-Benz Classic sells a digital vehicle data card for most passenger cars built 1986–2010 (AMG models excluded). It lists the model, original option codes, paint and trim, costs €130, and requires proof of ownership.
  5. ID
    GearboxThe five-speed 722.6 ran until June 2006 production; the seven-speed 722.9 (7G-TRONIC) followed, which in the US means 2002–2006 model years are five-speeds and 2007–2008 are seven-speeds. Check the VIN model year, the build month on the door-jamb label, and the dipstick: the 722.6 has one, the 722.9 does not. That matters for fluid specs and service intervals.
  6. ID
    Three lockersAll three locks are worked from the dash buttons and engage in sequence: centre, then rear, then front. If a light won't go solid, suspect the vacuum side before the axle.

Recalls & service bulletins

Open recalls follow the VIN, not the model. Run yours through NHTSA before you buy, and ask the seller for dealer records showing recall work.

Importing & legality

Mercedes only sold the G 500 in the US from the 2002 model year. Earlier trucks either came through Europa International, which federalised them and issued US VINs, or arrived later as grey imports. NHTSA lets any vehicle at least 25 years old in, counted from its date of manufacture, so a European-market G 500 or G 500 Cabriolet built before late 2001 can now be imported under Box 1 of the HS-7 form. Check your state's titling and emissions rules before you buy one abroad.

Rules change and vary by state and country. Confirm with your DMV and a licensed importer before you buy.

Owning one

Baseline service, the repairs you’ll actually do, and where the manuals live.

Post-purchase baseline

After you buy it

Assume nothing was done and reset every fluid and filter in the first month: on a 15–25-year-old G 500 the expensive failures (722.6 shifts, diff locks, front axle seals) usually trace back to old fluid, perished vacuum lines or a skipped knuckle service. Read the tags on the transfer case and axles before buying fluid — W463 drivetrains changed through the years.

Oil in the plug wells means valve-cover gaskets — fix those first, then fit plugs, wires and any oil-soaked coil boots.

Coolant & thermostatMB 325.0-approved coolant (blue) mixed 50/50 with distilled water · ≈12.7 US qt (≈12 L) per AMSOIL [CONFIRM IN MANUAL]Now if history is unknown

Bleed carefully; replace the thermostat and any soft or swollen hoses while the system is drained.

Drop the pan, fit a new filter and gasket, and replace the 13-pin connector sleeve — ATF wicking through it ruins harnesses. Set the level hot, on level ground, with the 722.6 dipstick tool. US trucks built from 2007 have the seven-speed 722.9 instead — check the tag and use the fluid and procedure for that gearbox.

Transfer caseCheck the tag: many W463 cases take MB 236.14 ATF; earlier cases ran GL-4 gear oil [CONFIRM IN MANUAL]Now, then every 60,000 mi (MB interval quoted by owners)

For the hands-on owner

Common repairs

The jobs owners actually end up doing, rated for a competent home mechanic with a decent tool kit. Always confirm torque figures, fluids and procedures against the factory service manual for your VIN, and work safely — support the truck on stands, never just a jack. You do this work at your own risk; see the disclaimer. Some parts links are affiliate links.

Harmonic balancer (M113)
DIFFICULTY · 3 / 5TIME · ≈ 2.5 hoursSHOP COST · $250–450 labor
SYMPTOMSVibration at idle, a visibly wobbling crank pulley, rattle or chirp that changes with RPM, cracked or bulging rubber, belt squeal. Don’t keep driving it: if the outer ring lets go you lose power steering, charging and the water pump.
THE FIXRemove the belt and fan as needed, hold the crank pulley with a counter-hold tool, and break the 27 mm centre bolt loose. Fit the new balancer with a new front crank seal while you're there; a new centre bolt (112 031 00 71, M16 × 1.5) is cheap insurance. MercedesMedic's M112/M113 guide gives the bolt torque as 200 Nm plus a further quarter turn (90°) — confirm against WIS for your engine.

Oil filter housing gasket leak (M113)
DIFFICULTY · 2 / 5TIME · ≈ 2–3 hoursSHOP COST · Parts cheap; most of the bill is labor
SYMPTOMSOil collecting at the top front of the engine in the V, running down the front of the block onto the belt, pulleys or harmonic balancer; a burning-oil smell once it reaches hot parts. Owners often get misdiagnosed first — on one M113 the first shop blamed the power steering pump.
THE FIXConfirm the source by degreasing the engine and checking again after a drive. Remove whatever sits over the housing (air intake ducting and covers), unbolt the housing, clean both mating faces completely and fit new seals. Use genuine Mercedes or Elring seals, torque to the factory figures, then degrease again so any remaining leak is easy to spot.
TOOLS & PARTSMetric sockets and Torx/E-Torx bits · torque wrench · gasket scraper (plastic) and brake cleaner · new oil filter housing seals (genuine or Elring) · fresh oil and filter while you’re in there
Valve cover gaskets & breather hoses (M113)
DIFFICULTY · 3 / 5TIME · A weekend morningSHOP COST · ≈ $200 parts vs ≈ $2,000 shop quotes (owner report)
SYMPTOMSOil on the coil packs, plug leads and the top of the exhaust manifolds; a burning smell after a drive; in bad cases oil reaching the plugs and causing misfires. Breather hoses on the same engine family crack and leak too, so leaks around the covers aren’t always the gaskets.
THE FIXRemove the intake ducting, then the coil packs and plug leads (label them — the M113 runs two plugs per cylinder), then the cover bolts. Lift the covers, clean every trace of old gasket and sealant, and fit new gaskets plus the bolt grommets. Replace the crankcase breather hoses at the same time; where sealant is specified, owners report a continuous bead with no gaps and spotless surfaces is what stops repeat leaks. Torque the cover bolts evenly to the factory figure — overtightening distorts the covers.
TOOLS & PARTSSockets and Torx bits · torque wrench (low range) · plastic scraper and brake cleaner · valve cover gaskets and bolt grommets (genuine or Elring — owners report aftermarket gaskets leaking) · breather hoses · Mercedes-approved sealant where called for
Diff locks won’t engage

SYMPTOMSOne or all locks refuse to engage, or engage then drop out; sometimes paired with central-locking oddities. The fault is usually the vacuum system, not the differentials.
THE FIXConfirm vacuum at the transfer-case hose. Then work from the pump and reservoir (front-left wheel well) through the manifold and the switchover valve block on the firewall, teeing in a gauge at each segment. One owner’s 2005 G 500 fault was a split plastic connector inside a rubber Y fitting under the brake booster. Change transfer-case and diff fluids and bleed the hydraulic locker lines while you’re in there.

G 500 questions, answered

What’s the biggest tire I can fit without a lift?

A 275/70R18 — roughly a 33-inch tire — on the factory 18-inch wheels. Owners on Expedition Portal report it fits an unlifted G 500; one saw rubbing only on aftermarket ET63-offset wheels. A 285/65R18 can rub slightly at full left lock. Re-code the tire size with a Mercedes diagnostic tool so the speedometer and ESP stay accurate.

7,000 lb with a braked trailer, across 2002–2008 G 500s. Unbraked limits are far lower — check your owner’s manual and local law.

What kind of fuel economy should I expect?

EPA figures for a 2003: 11 mpg city, 13 highway, 12 combined, on premium fuel. Bigger tires, a roof rack and a lift make it worse.

Does it have low range?

Yes. The two-speed transfer case gives you low range for crawling, alongside full-time four-wheel drive.

Can I use the diff locks on pavement?

No. Locked differentials stop the wheels turning at different speeds, so on grippy surfaces the driveline binds and tires scrub. Use them on dirt, sand, snow or rock at low speed, and unlock before you’re back on tarmac.

What’s the difference between a G 500 and a G 550?

Mostly the engine and the badge. In the US the 2002–2008 G 500 has the 5.0-litre M113 V8; from 2009 the same W463 truck became the G 550 with the 5.5-litre M273 V8. The seven-speed automatic isn't a G 550 exclusive: US G 500s switched from the five-speed 722.6 to the seven-speed 722.9 for the 2007 model year (production from June 2006). See the next question for how to tell which one you have.

How can I tell whether my G 500 has the five-speed or the seven-speed automatic?

Go by the build date, then confirm on the truck. Mercedes switched the G 500 from the five-speed 722.6 to the seven-speed 7G-TRONIC (722.9) in June 2006 production: Germany's ADAC catalogue ends the five-speed G 500 at 06/06 and starts the 7G-TRONIC version the same month. In North America that lined up with the 2007 model year. The EPA lists the 2006 G 500 as a five-speed and the 2007 and 2008 as seven-speeds, and Mercedes-Benz Canada's 2007 release says the G 500 "now gets" 7G-TRONIC. To check yours: (1) the 10th character of the VIN is the model year, so 6 means a 2006 five-speed and 7 or 8 means a 2007–08 seven-speed; (2) the certification label on the driver's door jamb or B-pillar gives the month of manufacture, and anything built from June 2006 should be a seven-speed; (3) confirm on the truck: the 722.6 has a transmission dipstick tube with a locking cap, while the 722.9 has no dipstick and is checked at the fill and overflow plug on the pan. The type number on the gearbox's own ID plate, or a Mercedes-Benz Classic data card, settles it for good. Double-check trucks built right around the change, and European Grand Edition trucks, which ADAC lists through August 2006. The G 55 AMG kept the five-speed.

Will it fit in my garage?

Kelley Blue Book lists a 2002 G 500 at 185.6 in (about 15.5 ft) long on a 112-inch wheelbase. Mercedes' 2015 G 550 manual gives a height of 76.8 in (1,951 mm), so plan on about 6 ft 5 in before you add a roof rack or a lift — and note that the same manual says the factory roof isn't rated for loads.

Is the G 500 reliable?

The frame, axles and V8 are tough; the age-related jobs are predictable — harmonic balancer, vacuum lines for the lockers, axle seals, steering damper, sunroof drains. A truck with records of these is a far safer buy than a low-mileage one that’s never been touched.

How do I know if a G 500 is a real AMG?

Check the VIN and the data card. Many standard Gs wear AMG bumpers, wheels and badges, so the badges alone tell you nothing.
