Default Rear diff shot

I took my 2000 RS in for a whirring noise when under acceleration and they diagnosed it as a bad rear diff. Said they also have to replace the "drive shaft", but he might have meant half shafts the way he was talking.

I thought this was interesting as I remember people on the board saying the rear diff was pretty indestructible. The service mgr also said it was a rare thing to go out. Rare enough that the parts had to be special ordered. I will try to talk to the actual subaru tech when I bring it back in for the service. AFAIK, this will all be covered under the drivetrain warranty.

More updates when I get the diff replaced...

*edit* This is all with stock power, no rallying or tracking the car, etc.

I know someone who thought they had a bad rear diff too, turned out to be a wheel bearing and an axle.

Well, the service manager initially said it was a wheel bearing, but then called back and said 'rear diff and drive shaft' were bad. Wheel bearing is usually noticable as a different sound when turning, right? This is definitely drivetrain as it is very noticable when the drive train is loaded (as in accelerating or maintaining speed) and the sound almost totally goes away when decellerating.

Before I took it in I could have sworn it was coming from up front and thought it was transmission or wheel bearing.

I should hear from them re: parts arriving next week.

Do u have aftermarket suspension like shocks and springs?

If you do, will warranty cover it still?

yes they can not void warrenty due to normal aftermarket additions like struts and springs.

if they give you any trouble put up a big fight, everything i have read and seen says they can not void a warrenty for anything like this.... of course depending on milage.
