Known Problems

Ignition wire failures can cause a rough idle or intermittent engine misfire and there might not be a Check Engine light.

Leaks at the front and/or rear differential pinion seal and from the transfer case are common. Leakage from the transfer case normally occurs at the case-mating surfaces and require removal of the transfer case to reseal.

Engine oil leaks from the valve cover gasket, oil pan gasket and timing cover gasket are common.

Due to warped front brake rotors or variations in the thickness of the rotors, brake pulsations may develop. The best method to reduce pulsations is to use an "On the Car" brake lathe (as long as the rotors are suitable for turning). "On the Car" equipment can correct variations (or "runout") in the rotor surfaces because it also corrects variations in other components (e.g. the hub).

The throttle position sensor (TPS) may fail causing intermittent drivability problems like hard starting, stalling, and/or hesitation when accelerating. A failed TPS will require replacement, proper diagnoses should always be performed before replacing any parts.

The throttle body may accumulate an oily, black residue in the bore and on the throttle plate causing hard starting or possibly stalling when coming to a stop. The throttle body should be cleaned during regular maintenance but do not spray cleaners directly on or at the throttle position sensor (TPS) as this can damage the sensor.

A minor brake pedal pulsation may be felt at highway speeds and can be caused by rough surfaces on the brake rotor. Low quality brake pads may deposit material onto the rotor surfaces causing variation on the brake rotor surfaces. The front brake pads may need replacement and the brake rotors should be machined or replaced, if necessary.

Some models are susceptible to rear main oil seal failures in dirty or dusty conditions. As dirt and dust collect on the oil seal, the abrasion wears through the sealing surface. A rubber plug, installed above the starter, is being used in production that prevents the dust entry near the seal and extends the life of the seal. The plug is available from MOPAR and should be installed any time a rear main seal service is performed.

A ticking type noise may be noted from the engine area due to an exhaust manifold that has cracked where the pipes are welded; cracked manifolds should be replaced.

Floor pan rust and corrosion typically happens where salt or mud is allowed to accumulate on the vehicle. Holes drilled in the floor can contribute to rust if the bare metal is not painted or protected with corrosion resistant coatings. Floor pan kits are available from Jeep and the aftermarket to repair rusted areas.
