  Q: How should the Driveshaft Center Support Bearing be checked and renewed on Mercedes-Benz 190E?

  A:

  Tear on the Driveshaft Center Support Bearing may lead to noises and vibrations during the run of the vehicle, and the driveshaft should be removed when checking the bearing. Rotate the bearing alternatively, holding it so that it can move freely without any freeplay; when difficulty is encountered in the rotation or a gritty feeling is present, then the bearing has to be changed. Check the rubber part for cracking or decay, which also requires renewal. To perform the renewal, a puller, hydraulic press, and appropriate spacers will be needed; in the absence of such equipment, it is better to turn to a Mercedes-Benz dealer. Start by stripping the driveshaft and creating alignment marks between the front and back sections; a few models already have alignment marks. Unscrew the threaded sleeve nut to which the rubber gaiter is attached, completely slacken the nut, and separate the two portions of the shaft. Optional: Unhook the rubber gaiter at the back fitting and then use a legged puller that fits on the end of the shaft to loosen the center mounting assembly by pulling it out, marking the direction the bracket was. Recover the front and rear bearing covers, support mounting bracket assembly, and carefully press the bearing out with a tubular drift. Check all parts for wear or spoilage, renewing as necessary; ensure that bearing protectors and the covering of the gaiter of a pivot are regularly changed, whether in good condition or not. Firmly hold up the mounting bracket and force the new bearing to fit in place with a tubular drift that actually comes into contact with the bearing outer race. Clean the driveshaft and secure the new rear protective cap, ensuring that the mounting bracket is properly in place, then clamp the assembly completely onto the shaft with the tubular drift only touching the inner race of the bearing. Install the new protective cap on top of the front and place the fitted new rubber gaiter in the shaft gully. Add a layer of molybdenum disulphide grease to the driveshaft splines, then proceed to slip the two halves of the driveshaft together, taking care that the alignment marks are all aligned properly. Lastly, install the rubber gaiter according to the threaded sleeve nut groove and reinstall the driveshaft.
