Centre diff bearing question - 93 WRX
 

As per title - it looks like I'm going to have to attempt to change the centre diff bearings in my 1993 WRX myself (TY752VB3AA gearbox, if that makes any difference).

Most guides feature the diff on the right, and give bearings to suit:

However I'm pretty sure I have the diff on the left (as my car is pre-98).

Are the bearings the same for both diffs? I can't find any information either way.

Thanks in advance!

Here are some of the bearing part numbers for a Rev B (1993/05-1994/09) WRX
Part numbers listed are superceded items so.......
Part code G44102 in the list refers to item G44101 on drawing
Part code G42008 in the list refers to item G42006 on drawing
Part code G23015 in the list refers to item G23012 on drawing

Those listed here for an early UK box are similar

Thank you!

Ok, this is really stressing me out so would really appreciate some further help!

On the above diagram, number 10 (aka G23012/G23015/806230150) looks like this (which appears to be the correct item for a Phase 2 transfer case):

However the part number corresponds to this:

What looks like the same bearing but without the tabs.

I'm looking to order a replacement along with a second hand centre diff unit - does anyone know which bearing I should order?

..Or should I just buy the second hand diff, bang it in, and hope the straight-cut-gears-sounding whine goes away before ordering individual bearings?!

Not sure where you are seeing the tabs unless you think the gasket behind it is part of the bearing ??

The bearing with carrier plate is for the later newage boxes

Just to confirm your gearbox is out of a revision "A" WRX of 05/1992 to 08/1993 vintage

Bearing is still 806230150

Oh my god, how did I not see that! What a relief - thank you so so much again for your help!

Don is good.
