I am changing the rear diff cog and I need to replace the bearing and races but I am finding there are several sizes and Toyota is being difficult with info other then trying to gouge the price.


Rockauto has them for 1/4 the price (Same make as the dealer is offering) but are showing 4 and the full float axel which is obviously not what I need.
For a 92 PU/4R V6 8" rear there showing 7.1", 7.8", 9.5" and 8.88" RG.
But it also shows the same #s for the 4 cylinder.


Am I to assume that all 4 cylinder, V6, 7.5", 8", 8" (4.88) and float axel diffs all use the same diff bearings (Not the pinion bearing of course)?

 

Did the stealership request the VIN# to try and locate it?

My local stealership parts guy always asked for the VIN but he still seemed like he wasn't qualified for his job. (he claims to have been there for 10+ years) He had constant trouble with the "new software on his computer" He has said that crap for years though.

What is the VIN# for the truck? I can see what I can find. Never hurts to have a second set of eyes. Also say again exactly what your truck is so I'm clear on it:
example: 1994 toyota pickup 2wd DX 22re

 

Its not that, I got attitude when I compared there price to Rockauto for the same make, They could try to be a little competitive.


Was thinking of going to another dealer and try to get the info but there out of the way.
I guess I could try and see if Autozone would be willing to do parts match.

 

Your rear diff is a V6 8".....some might refer to it as 7.8".

Thank you Zuk.
Autozone and rock auto have both gotten them wrong.
I pre ordered from Rockauto so I would have all parts on hand and get up to the point of dropping the carrier into the diff only to find the bearings to small (They list and sent 32010X).
Rush ordered Autozone Timken 17887 since the only alternative was the 32010x again and had to wait two days only to find those were even smaller but did not buy them.

The Koyo you mention are whats marked on my old race.
The ones Rockauto sent match the dimensions they list and are to small.
I checked all there listing all the way back to 1987 4R, PU and 4cyl and there all the same, But its the wrong bearing.


So both Rockauto and Autozone are selling the wrong bearings?

 

The Timken cone is JLM104910.
