Diff Axle shaft seal
« on: 28 July 2022, 13:54:37 »
I have a guaranteed good second hand diff, for the 2ltr omega. As the one on it is no good. The whine is unbearable from it. I want to change the axle shaft oil seals on the new one, while it is off the car.  Can someone tell me if this is the correct seal I need?

https://www.ebay.co.uk/itm/143186723717?hash=item2156980385:g:QSQAAOSwe~lcmMRi#vi-desc-maincntr

Also do the old seals just pull out, and new ones tap in or does the circlip that can be seen have to come out, or does it not needed to be touched?

Thanks for any help.

Also forgot to ask, can I just fill it with EP90 as it was drained for sending. Or is there some other thing that has to be used? It is not a LSD diff.

Thanks for any help.

Before undoing anything you will need to mark the face of the nut and the diff body as the nut is set to a specific preload and when refitted needs to be exactly in the same place as before being removed.

You will find a guide in the  "How To Replace Diff Pinion Seal" in the how to section...follow to the letter as your newly replaced diff will be toast in a few miles otherwise. :-[

Oil and link to seal seem to be correct  :y

Err - are you talking about replacing the two "Axle seals" or the (one) "Input shaft/pinion seal"? Or all 3?

The two "Axle seals" where the axle shafts go into. I want to change the seals, while the diff is off the car. Not touching the pinion shaft seal, I have been guaranteed that it is OK.

Never done those on an Omega, but the nut and preload stuff that amba is talking about are for the pinion I think?

Yes preload for pinion oil seal only...wasnt sure if you intended doing a full refurb of the diff as easier off the car
