Hey guys,

Although I didn’t see anything about this when I searched, I expect that there is probably
already a thread that covers this...but guess what? I’m just happy to be in here, posting a new
thread! I miss this place!

Anyway, I was wondering if anyone had ever bothered making a list of the part numbers(Timken, National, etc.)
for the bearings in the mk3 LSD. Specifically, the inner and outer pinion bearings, and both side bearings.
Also, it wouldn’t hurt to know the pinion and shaft seal part numbers as well.

Thanks in advance.

Thank you, Piratetip!

I should have just messaged you directly, knowing that diffs are your specialty. I'm wanting to rebuild my diff, because back when I put a Weir stage 1 and solid spacer in, I think I messed up the preload, because when I add heavy load(boost) or engine brake from highway speeds, I get added noise. So while I'm in there, I want to swap out ALL the bearings.

Good plan.
Take your time and get all the specs right.
