I have been trying to research the parts need to replace the bearings in my S4 TII rear-end. I have looked up both the FSM and found this How To https://www.rx7club.com/1st-generati...torial-711712/.

In the Thread it states that there are 4 bearings however the part diagram and FSM show a total of six. Two Pinion Pilot bearings, Two different center pinion bearings(different part number show facing different directions, but have the same Diagram number), and Two Axle/Diff bearings.

Rockauto was confusing as well as there is a larger number of bearings listed. OEM prices are a bit high($311.50 Akins before shipping.) and I would like to make this affordable. I have yet tear down the diff due to weather.

 

go right to the dealer, mine was under 200? for the 4... 2 pinion, 2 carrier. my LSD was great so i didn't tear it down, just had a bad pinion, so i replaced all 4.

 

there are two diff side bearings, 0118-27-350A. then the pinion has three. the rear (closest to the gear) is 0604-27-220. the center (centre) is 0755-27-210. the front is P016-27-143. it is pointing to two things, but i think there is only the one bearing.

the side seals are P016-27-238. the front seal is P090-27-165.

 

I looked up the parts in the parts diagram and it states it needs two pilot bearings. I think my best bet is to tare her apart and look just to be sure.

 

the n/a has 3?? this turbo of yours has 2.

While were on the subject, how is the stock s4 t2 lsd with more shims for extra lockup?

 

Better than nothing
