  Q: What is a driveshaft and universal joints and its function in a Chevrolet C1500 and K1500?

  A: A drive shaft is a tube or set of tubes that transfers power between either the transmission or the transfer case on 4WD models and the differential. Universal joints are positioned at each end of the driveshaft as well as in the center of two-piece driveshafts. On 2WD models, their driveshafts have a front splined yoke that slips into the transmission extension housing so that their length can increase and decrease. An oil seal prevents leakage at this point. Driveshafts on 4WD models tend to come with a splined yoke / companion flange at the transfer case end while two-piece driveshafts typically sport a slip joint at the front of the rear section. Center bearings carry the driveline when two-piece driveshafts are used. It's not often you need to service a drive shaft assembly but if anything goes wrong, replace worn universal joints since they have had to be greased for life. The drivshaft must be cleaned and checked for damage whenever lifting vehciles during servicing, ensuring that small weights used in balancing it do not detach. In most instances, noise or vibration when driving signifies trouble in the drivshaft whereas road testing can clarify whether this is right.

  Q: How to universal joint replacement for Chevrolet C1500 and K1500?

  A: Before beginning the universal joint replacement procedure, it's crucial to have a universal joint service kit specific to your vehicle. First, remove the driveshaft. For the outer snap-ring type universal joint, place the driveshaft on a bench equipped with a vise. Remove the snap-rings using small pliers, then support the cross (also called a spider or trunnion) on a short piece of pipe or a large socket and use another socket to press out the cross by closing the vise. Press the cross through as far as possible, grip the bearing cup with locking pliers, and remove it. A universal joint repair kit will provide new components like a trunnion, seals, bearings, cups, and snap-rings. Inspect the bearing cup housing in the driveshaft for wear and damage; if it's too worn, the driveshaft will require replacement. Ensure the dust seals are correctly positioned on the trunnion. Using a vise, press one bearing cup into the yoke about 1/4-inch, use grease to keep the needle rollers in place, insert the trunnion into the partially installed bearing cup, insert the needle bearings into the opposite cup, and press both cups into place using a slightly smaller socket. Install the snap-rings to secure the cups. For the injected plastic (inner snap-ring) type, if the joint has been previously rebuilt, remove the snap-rings located on the inner part of each bearing cup. For first-time rebuilding, it won't be necessary to remove the snap-rings; the pressing operation will shear the molded plastic retaining material. Press out the bearing cups, remove the trunnion (cross), and clean all plastic material from the yoke. Reassembly is similar to the outer snap-ring joint, but the snap-rings are on the inner part of each bearing cup. When installing the bearing cup, press it in until the snap-ring can be installed, and if needed, strike the yoke with a hammer to allow the snap-ring groove to move into position.
