1994 Jeep Grand Cherokee Axle Problems

The 1994 Jeep Grand Cherokee followed the majority of the manufacturing and design specifications for the 1993 model, with a few updates, such as side door guard beams and the option for V8 engines. This design was not remodeled until 1999, and Consumer Guide writers identified several problem points in the line of vehicles, including: air-conditioning, axle and transmission problems, engine misfiring, fuel pump problems, vehicle vibration and chronic oil leaks.

Mismatched Tires

When driving with uneven tires on the 1994 Jeep Grand Cherokee, such as a doughnut tire or even the factory supplied spare, special precautions must be taken and a replacement tire found as soon as possible. Cases have been reported in which the axle has overheated and caused vehicle fires.

Viscous Coupling Failure

In some cases, the couplings in the vehicle's transfer case have been known to fail, often in vehicles with less than 100,000 miles. A particularly dangerous problem, this can cause a lock-up of the front and rear axles, making the vehicle hard or impossible to control.

Differential Clip Failure

Several incidents have been reported of the rear axle breaking at the differential clip, causing the right rear tire to fall off while the vehicle is in operation. These incidents are reported to have occurred without warning and often at high speeds. No recalls have been made on the part, and manufacturers insist these failures are isolated incidents.
