If you're swapping out the ring and pinion gears of your 1979-2004 8.8" differential Mustang then you should be taking this opportunity to install new seals and premium quality 2.25" diameter Timken bearings, especially if your Mustang has logged over 60,000 miles. This will save you money in the long run by avoiding possible future tear down of your differential.
