The 3.64lsd needs the front flange swapped.

Anything I should know about preload before having a driveline shop do this?

Yeah, it took a couple minutes with the differential in the air to realize the flange could be different.

The curious thing is, the early 525 3.64 flange is bigger than the 535 3.46 flange.

It's bigger because we have so much more torque.... our parts are beefier...






kidding.

Preload should not be a problem.
