DIAGNOSTIC INFORMATION AND PROCEDURES

PROPELLER SHAFT DIAGNOSIS

Buick Enclave. Propeller Shaft
Fig. 1: View Of Propeller Shaft

Review the propeller shaft system function. Refer to Propeller Shaft Description and Operation.

Inspect for loose or missing propeller shaft-to-flange bolts (2) and (4). Tighten or replace as necessary. Refer to Propeller Shaft Replacement.

The propeller shaft (3) and the constant velocity (CV) joints are not serviceable. The CV joints and seals should be inspected periodically, whenever the vehicle is serviced.

The CV joint seals should be inspected for the following:

Carefully pinch the seal and feel for the presence of grit

The CV joints should be inspected for the following conditions:

The propeller shaft must be replaced if any of the above conditions exist. This will ensure that the propeller shaft continues to operate as intended and does not damage the other driveline components.

Removal Procedure

NOTE: Before removing the propeller shaft from the vehicle, paint or scribe reference marks on the transfer case flange to the propeller shaft flange and the rear differential drive flange to ensure minimal driveline system imbalance.

1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.

2. Mark the relationship of the front propeller shaft (2) to the transfer case drive flange (1).

9. Using a hammer and the brass drift or punch, remove the propeller drive shaft from the transfer case drive flange (2).

10. Remove the propeller shaft (1) from the rear differential drive flange (2).

11. Support the propeller shaft at the transfer case drive flange.

12. Remove the center support mounting bolts.

13. With the aid of an assistant, remove the propeller shaft from the supports and the vehicle.

Installation Procedure

NOTE: Align the paint or scribe reference marks on the transfer case flange to the propeller shaft flange and the rear differential drive flange to ensure minimal driveline system imbalance.

1. Clean the mounting bolts for the center bearing, front and rear propeller shaft drive flanges. Apply threadlocker to the bolt threads. Refer to Adhesives, Fluids, Lubricants and Sealers.

2. With the aid of an assistant, position the propeller shaft on the supports.

3. Align the reference marks on the front propeller shaft (2) to transfer case flange (1).

CAUTION: Refer to Fastener Caution.

7. Tighten the center bearing mounting bolts to 58 N.m (43 lb ft).

8. Install the remaining mounting bolts (1) from the propeller shaft to the rear differential yoke and tighten to 58 N.m (43 lb ft).

9. Remove the supports from the vehicle.

10. Lower the vehicle.

DESCRIPTION AND OPERATION

PROPELLER SHAFT DESCRIPTION AND OPERATION

Buick Enclave. Propeller Shaft
Fig. 13: View Of Propeller Shaft Assembly

The propeller shaft assembly is a 2-piece design. The front shaft consists of a plunging A-type constant velocity joint at the front and a universal joint and yoke at the rear.

The rear shaft consists of a center bearing and a center yoke, which are pressed onto the rear half of the propeller shaft and retained by a snap ring. The front and rear shafts are joined together at the yokes with a universal joint. The rear shaft attaches to the axle with a flange which is attached to the rear shaft with a universal joint.

The center bearing provides support where the front and rear shafts mate and is bolted to the underbody. The front constant velocity joint is bolted to the transfer case and the rear universal joint flange is bolted to the rear differential.

There are no serviceable parts on the propeller shaft. The propeller shaft is serviced as an assembly.
