Final Drive 0BC - arrow - and 0AR






• "0AR" is always on the rear final drive housing. The changes to the housing are what differentiate the "0BC" final drive from the "0AR" final drive.

• The locations of the threaded holes - arrows - for attaching the crossmember to the rear final drive are also different.






• The "0BC" final drive has 4 threaded holes - arrows - in its housing, used for attaching the crossmember. In addition to this, there is an additional threaded hole under the flange/driveshaft used for attaching the final drive to the subframe.

The other data is not needed.

• When replacing a rear final drive, always pay close attention to the code, the PR number and the engine code. This is the only way to make sure the allocation is correct.
