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.
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.
Poor connections of the ECU wires at the bulkhead can cause erratic RPMs and engine-stalling. The repair typically involves either bypassing the connector wires or cleaning and replacing spread terminals in the connector.
Be sure to verify starter replacement procedure before replacing the starter. A new starter replaced the older design and does not use a shim in the installation. Incorrect use of the shim can cause starter noise or may damage the starter.
The outer exhaust manifold studs can break and cause exhaust leaks, commonly noted as a ticking type noise. The outer studs, clamps, and nuts will need to be replaced and are now being tightened to a reduced torque value (20 Nm/180 in lbs).
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.
Child seat tether anchors are available from Chrysler and can improve the performance of child restraints. Each tether kit has all the necessary parts and detailed instructions according to our technicians.
Due to the design of the reverse gear system in the AX-15 manual transmission, it may block shifting into reverse one out of every ten attempts. An updated reverse gear is available if the concern becomes more frequent.
