Rear Differential Bushing Leak

BossJ

So this all started because I saw that burnt oil/grease on the exhaust.

The car is running perfect other than that. So then they put it up on the lift and saw the bushing and the drive shaft issues.

So I don't know of when / how / or where I would of damaged the driveshaft - the mechanic was vague about the issue - it sounded more of a let's do this to avoid other issues down the road than an immediate issue.

He said there's more oil or 'grease' on it than he'd like to see - He is afraid of it twisting / moving too much - if that makes sense?

It doesn't seem to be a 'pressing' issue but I am warrantied out on it... so I might as well do it - if it's covered.


(I bought this car used with 20k miles on it - the guy got it in 2015 and I bought it Nov 2019 - so it wasn't driven much. But this could of been an issue from the beginning. I got it from out of town - and didn't get my mechanic to look at it before the purchase.)

Thanks for the response!
