Center bearing inside the main shaft of the differential was torn all to hell. I'm trying to find the right replacement. It's slightly smaller than the axle bearings, and I don't want to make the mistake and buy the wrong part.

is it the one Right under the oil seal at the Diff flange?

Matthew Hamby

No, it's the one that sits inside of the housing. Between the spacer, and outer races. It's #9 in this diagram.

It's smaller than all of the other bearings.

Foxed.ca for parts manuals.
I have a manual in my lap that shows on page 2700-C.(page 231)
Turbo Diff (LSD)Part reference Number for Front is 27-141A But lists 2 part #'s even though they say that bearing is front and rear.
Part# (frnt) 0604-27-220
Part #(rr) is m025-27-210
here is the Kicker.
Some diffs show the bearing used in both spots,but then again in another diff with the 2 different part #'s.
Check in between pages 216 and 231.It will show all styles of diffs.You gotta be specific and what diff you have.

It's a stock non lsd diff off of a 88 rx7 convertible. That diagram is from the foxed.ca technical manual. I'll search for the parts manual. But like I said it's the center bearing, not the front or rear. Thank you so much for the research so far though.

More than positive that it is part number 27-141, thanks for your help. Although Jim Ellis Mazda parts only lists 27-141A, and then seems to list my part as 27-210. Can anyone confirm that this is correct?
http://www.foxed.ca/rx7manual/manual...%20CHASSIS.pdf That is the link of the parts manual, page H11. And here is the link to the Jim Ellis parts website.

according to the Pic in the manual they list it as a front bearing though...and in your pic you show separate parts but in the parts manual it looks like #9 and #10 are one complete bearing( race included)..same with #11 and #12.
(Front at Flange is 27-143a.I just got one,4 days ago.)listed as bearing ball, drive pinion.
............
Now REFERENCE # and Part Numbers can Vary.Do Not ask me why!,I run into this all the time with the Dealer up here.
Your Part REFERENCE Number is 27-141.BUT your part # IS:0755-27-210
Info for your Dealer: Section 2700 Page 216(pic,exploded view of diff) Page 217 Part Numbers.
Section: Differentials (Normal diff> L/turbo).
...I hope that helps..I really REALLY wish I had a scanner now..I could have just scanned and posted!
