  Q: What is a driveshaft and Universal Joint and how do you inspect it on Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?

  A: A driveshaft is a tube or pair of tubes that transmits power between the transmission and Differential, with universal joints located at either end and in the center of two-piece driveshafts. Single piece driveshafts have a splined yoke at the front that allows for movement during vehicle operation, while two-piece driveshafts have a slip joint on the front of the rear section and a center support bearing. The driveshaft assembly requires little service, with universal joints lubricated for life and replaced if problems arise. Inspection involves checking for dents, cracks, and oil leakage, as well as ensuring proper operation of universal joints and center bearings. Driveshaft mounting bolts should also be checked for tightness, and similar checks should be performed on the front driveshaft and driveaxles of 4WD models. Noise or vibration while driving may indicate problems with the driveshaft or other components.

  Q: How to replace a universal joint on Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?

  A: To remove a universal joint, it will vary depending on whether it is an outer snap-ring type or an injected plastic type. The snap rings are then removed with pliers, and force out the bearing caps. The U-joint is then removed and replaced with a new one and the bearing cap bores are inspected. For the injected plastic type, the snap-rings are removed if the joint has been rebuilt. Reassembly is the same as for the outer snap-ring joint, except the snap-rings are on the inner part of each bearing cap. If the joint is stiff after assembly, the yoke ears can be struck with a hammer to free up the joint.
