Driveshaft & Universal Joints: Driveshaft: Installation

CAUTION:

Driveshaft removal is a two-person operation. Never allow driveshaft to hang from the center bearing, or while only connected to power transfer unit (PTU) or rear driveline module flanges. A helper is required. If a propshaft section is hung unsupported, damage may occur to the joint, boot, and center bearing from over-angulation. This may result in driveline vibrations.

NOTE:

Lightly apply grease to the splines prior to installation.

NOTE:

It is recommend to replace the Power Transfer Unit (PTU) output shaft snap ring before the propeller shaft is reinstalled.

With the aid of a helper, install the driveshaft (1) into the PTU by wiggling the plug-on joint back and forth while pushing forward until splines engage and the driveshaft is fully seated.
NOTE:
If the snap ring is fully engaged, the driveshaft will not be removable from the PTU by hand.
Perform the push/pull test to verify the joint is fully seated over snap ring.
