  Q: What is the construction and attachment method of the driveshaft on Mercedes-Benz C240?

  A:

  The driveshaft features a tubular construction and can be either a one or two-section type. On AWD models, the front driveshaft is bolted to a flange at the front axle pinion and the transfer case. The rear driveshaft connects to the transmission or transfer case and the rear axle pinion flange through bolted flanges. Near its forward end, the shaft is supported on a ball bearing that is flexibly mounted in a bracket.

  Q: How to remove and install the rear and front driveshafts on Mercedes-Benz C240?

  A:

  The manufacturer recommends replacing driveshaft fasteners with new ones during installation. For the rear driveshaft, begin by raising the vehicle and securely supporting it on jackstands. Remove the rear portion of the exhaust system and the exhaust heat shield. Use chalk or a scribe to index the driveshaft's relationship to the differential axle assembly mating flange for correct alignment upon reinstallation. Remove the bolts securing the driveshaft flange to the differential pinion flange, turning the driveshaft or wheels as necessary for accessibility, then separate the driveshaft from the differential pinion flange. If equipped, remove the rear engine crossmember. Mark the center support bearing's relationship to the support bracket, loosen the bolts securing the center support bearing without removing them, and mark the driveshaft's relationship to the transmission companion flange before removing the corresponding bolts. Remove the fasteners securing the center support bearing and lower the driveshaft. Inspect the center support bearing; if it is rough or noisy, replace it. Connect the front end of the driveshaft assembly to the transmission extension housing, raise the center support bearing and bolt it loosely into place, then raise the rear end of the rear shaft, ensuring the alignment marks match. Tighten the fasteners and center support bearing bolts to the specified torque, completing the installation in reverse order of removal. For the front driveshaft on AWD models, remove the right side intake air duct and the fasteners securing the upper portion of the exhaust shielding plate. Raise the vehicle and support it securely on jackstands, then remove the lower engine cover(s) and the right side downstream oxygen sensor, unclipping the wiring harness from its retaining clips. Remove the fasteners securing the lower portion of the exhaust shielding plate and then the shield. Use chalk or a scribe to mark the driveshaft's relationship to the differential axle assembly mating flange. Remove the bolts securing the front end of the driveshaft to the differential mating flange, make alignment marks on the driveshaft and transfer case flanges, unbolt the flange securing the driveshaft universal joint to the transfer, and then remove the driveshaft. Installation is the reverse of removal; if alignment issues arise due to component rotation, place the vehicle in Neutral or rotate one wheel to achieve the original alignment, ensuring the universal joint caps are properly positioned in the flange seal before tightening the fasteners to the specified torque.
