Mercedes-Benz W140 driveshaft bearing and vibration
400 SES 320 L300 SE
Can the W140 driveshaft cause vibration at a certain speed range?
Yes. Driveshaft vibration typically appears at about 80–100 km/h. A worn center bearing can cause it, and replacing the bearing has removed the vibration. It is also worth checking the wheel balance.
What rumbles or growls from the driveshaft area on a W140?
A broken driveshaft center bearing support rubber can cause rumbling, and a worn bearing growls even at low speeds, under load or coasting. After the rubber or bearing is replaced the car runs quieter.
What should be noted when replacing the driveshaft center bearing on a W140?
The marks on the driveshaft ends must line up in the right position, otherwise the vibration may remain. Also check the condition of the flex joints and the centering sleeves. Removing the bearing requires a puller whose jaws reach the rubber part around the bearing.
