N2801GR-FE 4.0 V6KDSS · REAR LOCKER (TRAIL / TRD OFF-ROAD)

“Fifteen model years with the same V6, the same five-speed and roughly the same dashboard — and it sold better at the end than at the start. The most successful act of automotive stubbornness of the century.”

PART 01

Overview

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

The story

Toyota started building the fifth-generation 4Runner at Tahara, Japan, in August 2009, unveiled it at the State Fair of Texas on 24 September, and then essentially forgot to replace it. Production ran until August 2024. In between, the world got turbo fours, ten-speed gearboxes and touchscreens the size of tea trays; the 4Runner kept its 4.0-litre V6, its five-speed automatic and its roll-down rear window. Car and Driver called it "basically made of bronze and granite." Buyers called it a bargain at any price: US sales climbed from 46,531 in 2010 to a peak of 144,696 in 2021.

A PRADO IN A COWBOY HAT

Underneath, the N280 shares its platform with the J150 Land Cruiser Prado, the Lexus GX 460 and the FJ Cruiser, and like them it is a proper ladder-frame truck with independent front suspension and a live rear axle. It was built only in left-hand drive and never sold in Japan. The 4th gen's 4.7 V8 did not survive the transition; instead, every truck that mattered got the 1GR-FE V6, now with Dual VVT-i. A 2.7-litre four-cylinder lingered on 2WD models for 2010 only.

Launch trims were SR5, Trail and Limited. SR5 and Trail 4x4s got a part-time system with a two-speed transfer case; the Limited went full-time. All had A-TRAC brake-based traction control, but the Trail was the one that mattered: Crawl Control, an electric rear locker and the optional Kinetic Dynamic Suspension System (KDSS), kit that had previously been reserved for Toyota's posher off-roaders. Nobody was going to mistake it for a sports car — but nobody buying one wanted that.

THE LONG PLATEAU

The 2014 facelift brought the pointier face with projector headlamps, LED tail-lamps, a revised dash with the Optitron cluster, better brake lines and Trailer Sway Control — and, notably, no driveline changes. For 2015 Toyota added the TRD Pro, with TRD-tuned Bilstein remote-reservoir shocks (later TRD Pros, including Car and Driver's 2022 test truck, ran Fox dampers), TRD front springs and a front skid plate. For 2017 the Trail became the TRD Off-Road, mechanically the same truck with more badges. The Nightshade package arrived for 2019.

For 2020 every 4Runner finally got Toyota Safety Sense-P, plus a new head unit with Apple CarPlay and Android Auto. 2022 added push-button start, LED headlights and a TRD Sport trim that borrowed the Limited's X-REAS suspension and 20-inch wheels. 2023 brought a 40th Anniversary Special Edition limited to 4,040 units, and 2024 a TRD Pro-only paint called Terra. Car and Driver noted the truck hadn't had a major facelift in a decade; sales suggest nobody minded.

WHY THE TRAIL CROWD KEPT BUYING IT

It certainly wasn't the numbers. Car and Driver's 2022 TRD Pro needed 7.7 seconds to reach 60 mph, averaged 15 mpg overall and wallowed on pavement with "a huge amount of body roll and brake dive." What it had instead was a powertrain with no surprises: the 1GR-FE runs a timing chain with no scheduled replacement, the five-speed is old enough that every failure mode is documented, and the chassis is shared with enough Toyotas that the aftermarket is vast.

That aftermarket became the point. Trail4R alone has catalogued everything from transmission services to KDSS geometry correction, and suppliers sell lifts, control arms, sliders, bumpers, lockers and long-travel kits by the pallet. The KDSS debate became a 5th gen rite of passage: brilliant for a stock truck's flex and road manners, a headache once you lift it past about three inches. Owners argued about it for fifteen years, which is roughly how long Toyota left the truck alone.

THE AFTERMATH

The 6th gen arrived for 2025 on the TNGA-F frame shared with the Tacoma and Land Cruiser 250, swapping the V6 for a 2.4-litre turbo four and an optional hybrid. Even so, the old truck racked up 92,156 US sales in its final calendar year, according to Car and Driver. Its towing rating was 5,000 lb; the new one manages 6,000.

Used, the 5th gen is now the default 'buy once, build forever' SUV. TrueCar notes that 2010–2013 trucks under 150,000 miles can often be had for under $20,000, while Drivingline observed TRD Pros "regularly selling for well above MSRP." The usual inspections are frame rust, KDSS leaks, front axle seals and torn CV boots on lifted trucks. None of it is exotic, which is precisely why these trucks keep getting bought, lifted and driven into places a crossover would never come back from.

SIDEBAR · THE TRD PRO PAINT CALENDAR

Ten years, ten colours

From 2015 the 4Runner TRD Pro came in a model-year-exclusive colour alongside the usual two. Wikipedia's list reads like a paint chip archaeology dig: Inferno Orange (2015), Quicksand (2016), Cement (2017), Cavalry Blue (2018), Voodoo Blue (2019), Army Green (2020), Lunar Rock (2021), Lime Rush (2022), Solar Octane (2023) and Terra (2024).

It is a useful dating tool for buyers: a Lime Rush TRD Pro is a 2022, full stop. It also explains why some of those colours later trickled down to the TRD Sport and TRD Off-Road Premium, as Solar Octane did for 2024, once the TRD Pro had moved on.

Specs & capability

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

How it’s built

The N280 is the J150 Prado recipe adapted for America: a ladder frame, double-wishbone front suspension, a coil-sprung live rear axle on links, and the 1GR-FE V6 bolted to a five-speed automatic. The interesting parts are electronic and hydraulic — A-TRAC on every truck, a rear locker and Crawl Control on the off-road trims, and KDSS, which hydraulically links the front and rear anti-roll bars so they can let go when the axle needs to droop.

PART 03

Buying one

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

What they cost

Prices are firm. Late low-mile TRD Pros still change hands near or above their original sticker, while early high-mile SR5s are the entry point.

High-mile / early$15k–25k
Driver$25k–46k
Excellent / low-mile TRD Pro$50k–58.5k

Based on 22 Bring a Trailer sales from October 2025 to October 2026 (median about $38,000). The top sales were low-mile 2022–24 TRD Pros at $53,500–58,500. Prices move; checked October 2026. See live listings below.

What to check before you buy

  1. 01
    Frame and underbody corrosionSalt-belt and coastal trucks need a proper crawl underneath: frame rails, crossmembers, suspension mounts and the KDSS hard lines along the frame. Surface scale can be cleaned and treated (Trail4R's corrosion guide walks through it); flaking, holed metal is a different conversation.
  2. 02
    KDSS healthOn Trail and TRD Off-Road trucks, look for wet KDSS cylinders, weeping lines or a truck that leans. Owners on Expedition Portal describe leaking cylinders as difficult and expensive to fix. If it's lifted, ask how the KDSS was handled — Trail4R notes most lifts aren't designed around it.
  3. 03
    Open recallsRun the VIN at NHTSA. The big ones are the Takata passenger airbag inflator recalls covering 2010–2016 4Runners (19V-005, 19V-741 and earlier campaigns) and the Denso low-pressure fuel pump recalls for 2014–2015 (20V-012) and 2018–2019 trucks (20V-682).
  4. 04
    Lift quality and CV bootsA lifted IFS truck runs steeper axle angles. Check for torn CV boots and grease slung around the wheel well, aftermarket upper control arms on bigger lifts, and an alignment record. Trail4R's writer tore CV boots repeatedly from excessive droop until fitting limit straps.
  5. 05
    Front axle sealsGear oil where the CV axle enters the front differential means a leaking axle seal. It's a DIY job, but budget for it and check the diff level.
  6. 06
    Driveline fluid historyAsk for transmission (Toyota ATF WS only), differential and transfer case service records. Toyota's severe-service schedule changes diff oil every 15,000 miles when towing or loaded; many owners just do everything at about 30,000.
  7. 07
    Rear window and liftgateRun the power rear glass all the way down and up. A window that bounces back as if obstructed often just needs re-initialising or its tracks cleaned (see repairs), but a dead motor or regulator is a bigger job.
  8. 08
    Pick your year2014+ trucks get the facelift, better brake lines and Trailer Sway Control; 2020+ adds TSS-P and CarPlay. SlashGear flags 2013–2016 for higher complaint and recall counts. The 2.7 four was 2WD-only and 2010-only.

Spotting the real thing

Fifteen years of nearly identical bodies means the trim and hardware decide the price, and plenty of trucks wear TRD Pro badges they weren't born with.

Owning one

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

Post-purchase baseline

After you buy it

The 1GR-FE and A750 drivetrain are durable but rarely serviced past oil changes: Toyota calls most driveline fluids 'inspect' unless you tow, carry roof loads or drive dusty roads — which describes most 4Runners. Baseline everything, including the transmission, then put the propshafts on a grease schedule.

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.

Automatic transmission drain and fill
DIFFICULTY · 3 / 5TIME · Trail4R's author budgeted about 6 hours including parts runsSHOP COST · ≈ $174 in fluid and parts (Trail4R, Hawaii prices)
SYMPTOMSDue on mileage or unknown history; dark or burnt-smelling fluid. There is no dipstick — the level is set at temperature through a check plug.
THE FIXWith the truck level, remove the 24 mm refill plug first, then the 14 mm drain plug (about 5 qt comes out). Drop the pan (20 × 10 mm bolts), replace the filter and O-ring, clean the magnets and fit a new pan gasket; pan bolts 62 in-lb, filter bolts 7 ft-lb. Refill (Trail4R used 5.5 qt), then jumper OBD-II pins 4 and 13 to enter maintenance mode, cycle the shifter until the 'D' light stays solid, and check level through the 5 mm Allen check plug at 104–113 °F (solid D = in range, blinking = too hot). Let it drip to a dribble, refit the plug at 15 ft-lb.

SYMPTOMSGrease flung around the wheel well, a split boot, clicking on turns once dirt gets in. Lifted trucks with excessive droop tear boots on the lower control arm.
THE FIXJack only the side you're working on (keeps diff oil in), pull the wheel, unbolt the brake-line bracket (10 mm) and ABS sensor (12 mm), free the tie-rod end (19 mm castle nut) and remove the 35 mm axle nut. Unbolt the LCA (2 × 19 mm), swing the hub away and release the axle from the diff by tapping the inner cup while rotating it until the internal clip lines up. Mark the tripod and rollers, remove the C-clip, swap both boots with the kit's yellow (inner) and black (outer) grease, crimp the clamps with proper pliers — over-tightening tore Trail4R's on the trail — and refit with red Loctite on the LCA bolts and anti-seize on the hub splines.

THE FIXFront: unbolt the brake-line bracket (12 mm) and the caliper bolts, hang the caliper, push the pistons back, swap pads, pins and anti-rattle spring, knock off and replace the rotor. Rear: remove the caliper bracket bolts, release the parking brake before pulling the rotor (it has a drum-in-hat parking brake), fit new rotor, bracket and pads. Pump the pedal before driving. Trail4R lists 17 mm front caliper bolts but a reader reports 19 mm at 91 lb-ft — confirm against the FSM.

SYMPTOMSThe rear glass bounces back down as if it found an obstruction, or stays down. Common after a battery disconnect or an obstruction event.
THE FIXInitialise it: hold the switch down until the glass is fully open, then hold it up until it closes and keep holding about a second longer (Toyota TSB T-SB-0279-09 covers back-door window initialisation for early trucks). If it still balks, blow out the tracks with compressed air and wipe inside them with rubber cleaner on a doubled rag over a screwdriver. Check the hatch switch isn't physically stuck.

SYMPTOMSDue every 5,000 miles on dirt or dusty roads, or when towing/heavily loaded, per Toyota's schedule as quoted by Trail4R. Dry joints may pop when greased.
THE FIX4x4 trucks have two shafts with six zerks total (two spider joints and a slip yoke on each). Clean each fitting, pump NLGI No. 2 lithium grease into the spider joints until fresh grease shows at all four caps, then wipe the excess. Go easy on the slip yokes — Trail4R uses about four pumps rear and two front, since over-packing stops the shaft extending properly. The front shaft is tight against the exhaust; rotate it by hand for access.

Toyota 4Runner 5th Gen questions, answered

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

Trail4R's short answer is 32 inches. Stock is 265/70R17 (31.6 in). A 275/70R17 or 255/75R17 (about 32.1 in) shouldn't rub; a 285/70R17 (32.7 in) is 'questionable' and may need a body-mount chop; 255/80R17 (33 in) and anything bigger needs a lift and trimming. Tire brand and wheel offset change the outcome.

SOURCE · TRAIL4R
Which trims have the rear locker?

The Trail (2010–2016) and its renamed successor, the TRD Off-Road (2017–2024), which pair the electric rear locker with Crawl Control and Multi-Terrain Select. SR5 and Limited owners who want one retrofit an aftermarket unit — Trail4R documents an Eaton E-Locker install in an SR5.

Do I want KDSS?

If you'll stay stock or near-stock, yes: owners praise the reduced body roll and slightly better articulation. If you plan a big lift or long travel, it's a complication — Trail4R puts the practical lift limit at about 3 inches and lists bracket, sway-bar and panhard fixes for lifted KDSS trucks. Leaking KDSS cylinders are an expensive repair.

SOURCE · EXPEDITION PORTAL / TRAIL4R
Part-time or full-time 4WD?

SR5, Trail and TRD Off-Road 4x4s use a part-time two-speed transfer case with no centre differential, so 4H locks the front and rear driveshafts together. The Limited used full-time 4WD. All trucks have A-TRAC.

SOURCE · WIKIPEDIA / TRUECAR
How much can it tow?

5,000 lb, per Car and Driver. The 6th gen raised that to 6,000.

SOURCE · CAR AND DRIVER
What fuel economy should I expect?

EPA-rated 16 city / 19 highway (17 combined) in later years. Car and Driver's 2022 TRD Pro averaged 15 mpg overall and 17 mpg on its 75-mph highway test, good for about 390 miles of highway range.

SOURCE · CAR AND DRIVER
Does the 4.0 V6 have a timing belt?

No — the 1GR-FE uses a timing chain with no scheduled replacement interval, meant to last the life of the engine. The serpentine belt is the wear item: Toyota calls for inspection at 63,000 miles and every 18,000 thereafter.

SOURCE · TRAIL4R
What are the fluid capacities?

Per Toyota-Club's N280 data: engine oil with filter 6.2 L (Trail4R refills with about 6.6 qt of 0W-20); ATF WS 10.7 L total; front diff 1.55 L (part-time) / 1.40 L (full-time); rear diff 2.70 L without locker / 2.65 L with; transfer case 1.00 L (part-time) / 1.40 L (full-time); coolant 10.5 L. Diff oil is Toyota LT 75W-85 GL-5.

Which years should I buy or avoid?

There's no bad engine year, so buy on condition. 2014+ gets the facelift and upgraded brake lines; 2020+ adds TSS-P safety tech and CarPlay. SlashGear singles out 2013–2016 for higher complaint and recall counts. Whatever the year, confirm the Takata airbag (2010–2016) and fuel pump (2014–2015 and 2018–2019) recalls are closed.

What lift options are there?

Trail4R's shortlist runs from Old Man Emu (2.5–3 in) and Bilstein 6112/5160 to Eibach, Falcon, OME BP-51, Dobinsons MRR, ICON, Fox and King. Beyond about 2.5–3 in, plan on aftermarket upper control arms and, on KDSS trucks, sway-bar and panhard corrections.

SOURCE · TRAIL4R
Why does my truck lean to the driver's side?

Toyota puts heavy items — battery, driveshafts, transfer case, fuel tank — on the driver's side, leaving that side typically ¼ to ¾ in lower. Trail4R fixed it with a thicker top spacer on the driver's-side coilover than on the passenger side.

Who makes the good stuff, where owners gather, and who to watch.

Common modifications & who does them

SUSPENSION LIFTA 2–3 in lift with quality shocks makes room for 33s and fixes the stock nose-down rake.
UPPER CONTROL ARMSRestore alignment range and ball-joint angle once the front is lifted.
KDSS GEOMETRYLifted KDSS trucks need the sway bars and panhard bar brought back into line.
REAR LOCKER (SR5 / LIMITED)A-TRAC gets you far; a locker gets you up the ledge without drama.
MID / LONG TRAVELFor desert running, wider arms and bigger shocks — and goodbye to KDSS.
ROOF RACKRecovery boards, a tent or a spare fuel can need somewhere to live.
