1999-2004 Jeep Grand Cherokee WJ Differential Covers

Trail impacts hit the lowest points on the Jeep first, and the differential housing is right in the line of fire, which makes 1999-2004 Jeep Grand Cherokee WJ Differential Covers a smart investment for any WJ that leaves pavement. A heavy-duty cover absorbs the strikes that would dent or crack a factory stamped cover and keeps the gears inside safe.

 

Nodular iron and cast aluminum are the two most common aftermarket cover materials, with iron winning on raw strength and aluminum offering heat dissipation through a finned design. Making sure the replacement cover matches the Dana or Chrysler axle used in the specific WJ is critical, since different model years and trim levels came equipped with different axle assemblies.

 

Diff cover upgrades happen alongside other trail-prep projects more often than not. The front end gets a lot of attention on built WJs, and 1999-2004 Jeep Grand Cherokee WJ Front Bumpers is where that starts.
