Rubbing sound from rear diff
I just had my car in for a lot of random shit. One of the things was the loud rear diff rubbing sound when doing slow tight turns. There is a SIB for this issue, but it sounds like purely a noise thing and not a functional issue. My warranty is almost up and I am wondering if I should send the car back in and have the fluid changed per the SIB or if it's not worth the trouble. What do you guys think?
On a side note, I had a very minor squeak in my steering column fixed. When I got the car back I had a very MAJOR squeak in the rear deck. Wtf could they have done back there? Are they messing with me?
