Driveshaft & Universal Joints: Installation
Propeller shaft removal is a two-person operation. Never allow propeller shaft 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.
Lightly apply grease to the splines prior to installation.
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 propeller shaft (1) into the PTU by wiggling the plug-on joint back and forth while pushing forward until splines engage and propeller shaft is fully seated.NOTE:
If the snap ring is fully engaged, the propeller shaft will not be removable from the PTU by hand.
- Perform the push/pull test to verify joint is fully seated over snap ring.
- Position the rear center bearing in place, install the rear center bearing bolts (1) and tighten to the proper torque specifications. Refer to TORQUE SPECIFICATIONS
.
- Position the front center bearing in place, install the front center bearing bolts (1) and tighten to the proper torque specifications. Refer to TORQUE SPECIFICATIONS
.
- Align the index marks (3) on the rear propeller shaft flange and the rear pinion flange.NOTE:
The six bolts that are used to secure the propeller shaft to the RDU input flange MUST be replaced. Do not reuse the bolts/washers.
NOTE:Use of Anti-seized compound is prohibited.
NOTE:Make sure the double washer is flat/flush to the joint housing prior to tightening the bolt to avoid damage to the washer, if damaged replace bolt washer assembly.
NOTE:No torque verification is allowed after 10 minutes of the bolts being tightened to specifications. ANY MANIPULATION of the bolts after 10 minutes of being tightened will require the bolt(s) to be replaced.
- Install NEW propeller shaft bolts (1) and tighten to the proper torque specifications. Refer to TORQUE SPECIFICATIONS .
- Remove the cable ties holding the wood to the driveshaft and remove the wood brace.
