1999-2004 Jeep Grand Cherokee WJ Engine & Transmission Mounts

Engine mounts and transmission mounts on the WJ isolate the drivetrain from the chassis — when they wear out, that isolation goes away and the driver feels every combustion event through the steering wheel and floorboards. Vibration at idle that wasn't there before, a clunk under acceleration, and a driveline feel that has become harsh and imprecise are the symptoms that 1999-2004 Jeep Grand Cherokee WJ Engine & Transmission Mounts address.

 

Polyurethane mount upgrades on the WJ are stiffer than the factory rubber and transmit more NVH into the cabin — a worthwhile tradeoff for a trail-focused WJ where the added rigidity improves drivetrain response, but a consideration worth making deliberately for a daily driver where the stock isolation was part of why the truck felt comfortable. OEM-spec rubber replacements restore the original isolation without changing the cabin character and are the right call for any WJ that is primarily street-driven.

 

Worn motor mounts and transmission mount hardware that let the WJ's drivetrain vibrate into the chassis are what 1999-2004 Jeep Grand Cherokee WJ Engine & Transmission Mounts fix.
