Customer came in complaining of a howling rear end at low speeds that got worse as acceleration increased. The pinion seal had let go which caused two bearings to fail in the process. After a thorough teardown and inspection, all reused components were cleaned in our parts washer to ensure all metal shavings were gone and the rear end was reassembled with new bearings and fluid. Customer aslo took this opportunity to upgrade to 4.10s and updating his tuner to accept the new gear ratio.
