Jeep SJ Wagoneer & Cherokee problems to check before you buy
- Rust firstIt's the same body as the Grand Wagoneer, and Hagerty's buyer's guide for that truck calls rust the biggest concern: floor pans under the front carpet, the area where the fuel tank meets the body, the frame and underbody, and the front fenders. Original front fenders are no longer made. Floor, rocker and lower-quarter repair panels are still sold.
- Find out which 4WD system it hasThis matters for parts, fluids and how it drives. A one-lever floor shifter on a 1974–79 automatic is the Borg-Warner Quadra-Trac; a manual from those years has a Dana 20. The 1980–82 'Quadra-Trac' is really an NP219, and 1980–83 trucks may have a part-time NP208 or, from mid-1982, Selec-Trac with a dash switch.
- Listen in tight turnsThe factory manual describes Quadra-Trac 'stick-slip': a low grunting or rasping noise when turning slowly or parking. It's usually the wrong fluid, mismatched tires or uneven pressures. A much louder noise when driving straight points to a stretched chain. Team Grand Wagoneer's chain kit is aimed at trucks with more than about 120,000 miles or skipped fluid changes.
- Check the Chief is a ChiefThe real Chief from 1976 has wider axles and flared fenders and was only built as a two-door. On 1981–83 VINs, characters 6–7 read 16 or 17 for a two-door Cherokee and 18 for a four-door; 15 is a Wagoneer. Golden Eagles are Chiefs with a big hood decal, gold-painted steel wheels and denim seats, so look for more than a sticker.
- Drive it cold and hotHagerty's Grand Wagoneer specialist blames the Motorcraft carburetor for about 40% of owner headaches. Expect stumbling, hard hot starts and ignition faults on an untouched truck. NHTSA recalled 1975–76 trucks for ignition wiring connectors that could not carry enough current (78V-065).
- Work the tailgate windowThe power rear glass has to come down before the tailgate opens. Recall 87V-178 covers 1970–83 Wagoneers and Cherokees whose key-operated window kept closing if the spring-loaded key failed to return. Test the dash switch, the key switch and the glass travel.
- Look at the brakesEarly Cherokees had four-wheel drums as standard, with front discs optional; Wagoneers got front discs as standard from 1974. Check what's fitted and how old the steel lines are. Pre-bent stainless kits exist for 1977-on trucks.
- Budget for scarce partsSpecialists such as Team Grand Wagoneer and BJ's Off Road stock most mechanical and body parts. But on the later Grand Wagoneer, Hagerty's specialist estimates about 20% of restoration parts still come from salvage yards. Two-door-specific trim and glass are harder to find than Wagoneer parts.
The repairs Jeep SJ Wagoneer & Cherokee owners end up doing
| REPAIR | SYMPTOMS | DIFFICULTY | TIME | COST |
|---|---|---|---|---|
| Cure Quadra-Trac stick-slip and chain slap (1974–79) | A pulsing grunt or rasp when turning slowly or parking, worst after the truck has sat for a week; or a slapping noise against the case, even at idle, which means a loose chain. | 2 / 5 (fluid) · 4 / 5 (chain) | ≈ 1 hour (fluid) · a weekend (chain) | Parts plus labor |
| Rebuild the carburetor or convert to throttle-body injection | Stumbling or stalling cold or hot, hard hot starts, rich running, fuel smell. | 2 / 5 (rebuild) · 3 / 5 (TBI) | ≈ An afternoon (rebuild) · a weekend (TBI) | TBI conversion about $2,000 in parts plus up to $1,000 labor (Hagerty, Grand Wagoneer) |
| Fix the power tailgate window | The rear glass won't drop, so the tailgate can't be opened, or the glass binds and stalls. On 1970–83 trucks the key switch could stick on (recall 87V-178). | 2 / 5 | ≈ 2–4 hours | Parts plus labor |
| Patch floors, rockers and lower quarters | Wet or crunchy carpet, holes under the mats, soft rockers, bubbling paint low on the quarters and around the fuel tank. | 4 / 5 | ≈ Several weekends | Parts plus bodywork labor |
| Selec-Trac or NP208 won't engage 4WD (1980–83) | The 2WD/4WD switch does nothing, the 4WD light stays on or off, or the truck stays in one mode. | 2 / 5 | ≈ 2–3 hours | Parts plus labor |
| Tighten up sloppy steering | Free play at the wheel, a clunk when you turn, power-steering fluid weeping from the box. | 2 / 5 (rag joint) · 3 / 5 (box seals) | ≈ 1–2 hours (rag joint) · a day (box reseal) | Parts plus labor |
| Service the front hubs, bearings and ball joints (Dana 44) | Wheel play when you rock the tire top to bottom, a growl that changes with speed, uneven tire wear, grease flung on the inside of the wheel. | 3 / 5 | ≈ A day | Parts plus labor |
| Replace the rear main seal (258 or V8) | Oil dripping where the engine meets the transmission, with nothing wet above it. | 3 / 5 | ≈ A long day | $500–1,000 at a shop (Hagerty, 360 V8) |
