  Q: What should be considered before beginning the overhaul of CV Joint Boot on CV joints on Mercedes-Benz C320?

  A:

  If the CV joints show signs of wear, typically due to torn boots, consider all alternatives before starting the overhaul, as complete rebuilt driveaxles may be available on an exchange basis, saving time and effort. Begin by loosening the wheel bolts, raising the vehicle securely on jackstands, and removing the wheel. Next, mount the driveaxle in a bench vise with wood blocks for protection, ensuring not to overtighten. Remove the boot retaining clamps and slide the inner boot back, then wipe excess grease from the joint. Mark the positions of the bearing cage, inner race, and housing, then remove the ball bearings one at a time by tilting the cage. After all balls are removed, tap the inner race off the shaft, clean all parts with solvent, and inspect for damage or wear; if any components are unserviceable, replace the entire CV joint assembly. For assembly, wrap the splines with tape to protect the CV joint boot, install the boot and clamp, and tap the inner race back onto the shaft, ensuring alignment with the marks made earlier. Pack lubricant into the ball races, install the balls, fill the joint with grease, and position the boot correctly, adjusting the joint length and equalizing pressure inside the boot before tightening the clamps. For the outer CV joint, repeat the disassembly and assembly steps, ensuring to clean and inspect all parts thoroughly. Finally, for front driveaxles in AWD models, mount the driveaxle in a vise and follow the CV joint boot replacement procedure as illustrated.
