Removal of the drive shafts and drive axle.

Remove the bolts and lower the rear of the driveshaft. On 4WD models, remove the bolts and detach the front end from the transfer case. On 2WD models, slide the front end out of the transmission.

a) On an open road, free of traffic, drive the vehicle slowly until the transmission is in High gear. Let off on the accelerator, allowing the vehicle to coast, then accelerate. A clunking or knocking noise will indicate worn universal joints. b) Drive the vehicle at a speed of about 10 to 15 mph and then place the transmission in Neutral, allowing the vehicle to coast. Listen for abnormal driveline noises. c) Raise the vehicle and support it securely on jack stands. With the transmission in Neutral, manually turn the driveshaft(s), watching the universal joints for excessive play.

Since the driveshaft is a balanced unit, it's important that no undercoating, mud, etc., be allowed to stay on it. When the vehicle is raised for service, it's a good idea to clean the driveshaft(s) and inspect it for any obvious damage. Also, check that the small weights used to originally balance the driveshaft(s) are in place and securely attached. Whenever a driveshaft is removed, it should be reinstalled in the same relative position to preserve the balance.

Remove bolts that hold the driveshaft center bearing bracket to the frame crossmember. Make note of any spacers and save them for installation. Support the driveshaft with wire or rope.
