I need to replace the rear differential seal on my B6 2003 1.8T. How do I do this? And is it worth it to do myself if dealer can replace it for $165 total.

 

WTF??? i had a full inspection on mine done before i bought it last week, they said only thing wrong was tie rod end had a bit of play & that the rear diff seal was SWEATING. $150-parts....$700 for labour!!!

Has anyone else had to replace theirs recently?

 

Uh oh.....

I don't know if I want to do this now. Haven't had audi long enough to try something like this yet. Still learning the basics on it. And you need to get special tools. Might as well have dealer do it.

 

Rear diff. seals can be a little tricky. If you had access to a lift, I would say give it a shot. You do however need a seal driver specific to the rear diff. But even with the seal driver it would be very difficult without having your car on a lift with enough room to work. good luck

 

I have the same problem. I'm not going to worry about it until I see gear oil on the ground...

 

Mine has been sweating for 80K miles plus.

I just check the oil level once in a while to make sure it is OK.
