Does the exhaust have to come off to get the diff seal out?

 

[Neil.D]

Yes I beleive so. Presumably you are getting all 3 done?
Only the back boxes though surely.

 

[andy777]

No I am only doing the drive shaft seal as the leak is coming from that seal.
What do you mean by the back boxes?

 

[Neil.D]

Back boxes are just another way of saying cat back, or rear silencers,

sorry, Neil

 

[azaytsev]

Yes, in order to disconnect the driveshaft you need to drop the exhaust

Thanks guys I thing I am going to go the whole way and get the diff out and replace all the seals.
