I have a 98 with the 4T65E -hd Transaxle. I have an annoying grinding noise when turning right. It doesn't appear to be an issue otherwise. Under hard acceleration the shifts are crisp. The mounts "look" Ok . Are there problems related to the final drive assembly *+(Differential)?? Any ideas would be greatly appreciated.

Do you think you might want to look first at the inner fenders?

With the OE wheels certain tires will rub the plastic inner fenders on the right or the left when wheel turned to lock (the max turning angle).

With certain aftermarket wheels and tires, not the OE size, the tires may rub a lot due to differnt offset and what-not.

Sometimes if you inner fender liners were removed for some reason (belt change) then reinstalled they may not have been positioned properly.

If this is your issue you will be able to see the rubbing swath on the inner fender liners. Most likely on the lower edge aft of the axle...

At what speed do you hear the grinding? If the car's suspension in under load (as in a moderate/high speed turn), it could be the hub/wheel bearing giving a signal before failure.

it's present at all speeds. even 20 km/hr city cornering. I've checked the fender wells nothing obvious there.
