Why should we change the VLSD fluid?

Jordo! · 12-01-2013, 03:18 PM

I was about to comment, then it occurred to me that I wasn't sure which parts were directly affected by changing the dif oil either...

Here's an exploded view of the 370Z dif

Which parts are sealed and non-serviceable vs not?

Outer gears are affected by fluid change, whereas inner locking mechanisms are not?

Is that correct?

Ok, looking at that diagram. Part# 38760 is inside the carrier. That would be the VLSD unit that is sealed with silicone fluid. Your gear lube would be seperate from that. The bearings inside the housing is pinion bearing part#38120, and part#38140. 2 carrier bearings, left side and right side, part#38440. Those are lubed with your gear lube.

38760 Is the sealed VLSD Unit by the look and shape of it.
