Rear Driveshaft

Rear Driveshaft





The rear drive shaft in the (E83) X3 SAV with the M54 engine is a steel universal joint shaft (arrow on the right).





To minimize noise, a constant velocity joint shaft is used in the E53 MU.





Both style rear drive shafts are equipped with a deforming element.
The front section of the drive shaft is designed as a collapsing tube (1).
When the drive shaft is compressed (collapsed) it absorbs a defined force.
After collision or accident repairs, the drive shafts must always be checked for compression of the collapsing tube (refer to Repair Instructions for additional details).

Note: When the collapsing tube is deformed, the drive shaft must be replaced.
