Wheel bearing replace
 

I have a sneeky suspicion one of my wheel bearings are starting to go and think it the rear passengers side. Im looking on importcarparts for a rear bearing but theres two types, one for an sti with a R180 rear diff with CDC and one without.

How would I check which diff I have?

Also is it much of a job to do?

what makes you thin kit's going? if it's squaking, it's more likely to be a ceased calliper piston than a wheel bearing.
as for your quesrion, I can't answer i'm afraid, although I suspect CDC stands for centre diff controll ? in which case do you have DCCD or not would be the answer.
Let spomeone else confirm though, or call import car parts. they are very helpfull.

Okay thanks well I'm going to see stuart today about the starting problems today.

Its not a squeaking but its starting to whin.
