What is the 1990-1999 Jeep Cherokee Crankshaft Position Sensor (CPS) Failure Causes Intermittent No-Start and Hot Stalling?
The crankshaft position sensor on the 4.0L I6 and 2.5L I4 XJ is a classic thermal-failure item. Internal components and wiring degrade with age and heat, so the sensor works cold but drops signal once the engine reaches operating temperature. Without a CPS signal the PCM cuts spa… Repairs typically run $30-$300. Severity: high.
What is the 1990-1999 Jeep Cherokee Death Wobble (Front Solid-Axle Steering Oscillation)?
Like other coil-sprung, solid-front-axle Jeeps, the XJ is prone to 'death wobble' - a violent, self-sustaining side-to-side shaking of the front axle and steering, usually triggered by a bump or expansion joint at speeds above ~45 mph. It is caused by cumulative slop anywhere in… Repairs typically run $150-$900. Severity: high.
What is the 1990-1999 Jeep Cherokee Rear Unibody Frame Rail, Floor Pan and Rocker Rust (Structural)?
The XJ uses a thin unibody with no separate frame, and corrosion is one of its defining long-term problems, especially in salt-belt climates. The rear unibody rails rot where the fuel lines pass through the rail 'tunnel' and near the leaf-spring mounts, while floor pans under the… Repairs typically run $300-$3,000. Severity: high.
What is the 1990-1999 Jeep Cherokee Rear Main Seal Oil Leak (Two-Piece Seal Design)?
The 4.0L is notorious for rear main seal (RMS) leaks, in part due to its two-piece seal design. Compounding the diagnosis, the XJ engine sits nose-up, so oil from almost any upstream leak runs down and collects at the RMS area - the lowest point on the engine - making other leaks… Repairs typically run $150-$900. Severity: medium.
What is the 1990-1999 Jeep Cherokee Cracked Exhaust Manifold on the 4.0L I6?
The factory 4.0L exhaust manifold is well known for cracking, most often where the two down pipes converge into the collector. The cracks are frequently hairline and follow the factory welds; a major cause is that the manifold is rigidly mounted to the chassis while it moves with… Repairs typically run $200-$900. Severity: medium.
What is the 1990-1999 Jeep Cherokee Oil Filter Adapter O-Ring Leak (Commonly Misdiagnosed as Rear Main Seal)?
The 4.0L oil filter adapter uses three O-rings that harden and shrink with age (owners describe them becoming brittle 'like bakelite'). When they fail, pressurized oil weeps out and gets blown back onto the rear of the engine, so it is very frequently misdiagnosed as a rear main… Repairs typically run $15-$350. Severity: low.
