it runs great. even after the engine is warm. but after about 10 miles of driving, the rear end starts to shutter when accelerating around a turn (like turning from a stop sign). then after about 5 more miles it will start grinding. if anyone has any ideas, i can realy use the help. it has the local mechanics stumped...

If you have gone through the rear-end and are confident there are no issues there maybe look at the U-joints on drive shaft. U-joints will usually make a higher pitch squeal and or grinding noise and can come and go. Or possibly transmission is sending some vibration through drive shaft to rear-end.......

Check the axle code, you may have a limited slip rear end, if that is the case then put in some limited slip additive. You may have to drain out some differential grease to add the proper amount.
