You can Select Your Vehicle to check if 5L5Z-4602-D fits your vehicle.

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.

Repeat Step 3 for the front end of the driveshaft by making alignment marks on the driveshaft and transfer case flanges.

Installation is the reverse of removal with the following additions: a) Lubricate the slip yoke splines with chassis grease. b) Inspect the housing seal for damage and replace it if necessary. c) Do not allow the driveshaft slip yoke to bottom out on the output shaft. d) Ensure that the center bearing bracket is aligned at right angles or "square" with the driveshaft. If there were spacers under the bracket, install them again. e) Line up the paint marks on the rear yoke and the rear axle companion flange. f) Tighten all fasteners to the torques.

The slip yokes on the driveshafts and the right front drive axle.

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.
