Rear Driveline Module: Removal

CAUTION:

Never grasp halfshaft assembly by the boots. This may cause the boot to pucker or crease and reduce the service life of the boot.

Avoid over angulating the C/V joints when handling the halfshaft.

Halfshafts exposed to battery acid, transmission fluid, brake fluid, differential fluid or gasoline may cause the boots to deteriorate. Failure to follow these instructions will result in damage.

CAUTION:

Driveshaft installation is a two-person operation. Never allow driveshaft to hang from the center bearing, or while only connected to the transmission or rear axle flanges. A helper is required. If a driveshaft section is hung unsupported, damage may occur to the shaft, coupler, and center bearing from over-angulation. This may result in driveline vibrations or component failure.

NOTE:

The one speed Rear Driveline Module (RDM) is shown, the two speed RDM is similar.
