Mechanic specializing in rear end gear swaps, posi or just rebuild differential with all new bearings, races and seals. Can straighten your bent housing. Why put another 100k junkyard rearend in it when you can have it completely gone through and have a basically new rearend. Usually it just needs bearings. Once the bearings start to wear the ring & pinion contact pattern does not properly line up causing a whine or howling noise. For around $370 labor plus parts and oil you will have something that will last a long time. Also rebuild T5 transmissions. All work is on a carry in basis. Call for quote.
