Hi, I have a 1985 b2 coupe quattro with the early style rear diff.
I am looking for both the left and right seals, I think 23 & 24 on the diagram.

Part numbers are showing on oemepc as:

857525400A & 016409399B

I've been quoted £140 for left and £19 for right.

After searching those part numbers I have seen these:

https://www.buycarparts.co.uk/corteco/2094471

Anyone know if these would be suitable?

The right side seal is just a standard off the shelf rotating shaft seal which is available from any generic seal outlet - you just need the dimensions 45x60x8mm.

Audi Tradition do the left side for 95 Euros. Getting it ordered is a different challenge as the site is broken just now.

Hello Rosco,

I agree with Mike. I would not use a cheap AM part on the left. The right one is the same as the front once.
A tip for installing the left seal, make yourself a plate that almost covers the outer diameter of the seal wit an 8mm center hole. Use an M8 bolt to pull it in the right depth. I hope that helps, happy wrenching.

Ciao

Thanks for the fitting tips Werner, 034 Motorsports confirmed that the one they sell is the one that I need, however they want $35 shipping for a $20 part.

Unfortunately for the last 3 months the Audi Tradition store has been unable to accept payments, so might have to go with the 034 option.

Hi Rosco

The smaller seal is widely available such as below @ £6.34 incl p&p

Have you tried quattro corner for the larger seal?
Call Pete Reeve on 0121 476 0034

or you could try

$35 but you would need to establish postage.

Hope this helps - good luck :tup:

£41 delivered to UK + tax + Post Office charge so about £55 all in not too bad really for an otherwise unobtainable part, ask if anyone else needs one as postage will be same for 2 or more perfhaps ?
