Flushing and replacing differential fluid is one way to ensure that everything wears properly to avoid costly problems down the road. Your owner's manual will specify intervals for flushing and refill. While you're changing your fluid, it is a great idea to replace your drain/fill plugs and flange seals as these items are prone to leaks in your high mileage differential.
This kit is combined with the new ECS Magnetic Drain and Fill plugs to help keep abrasive and ferrous metal particles from circulating through the differential. These new plugs also use a very common and handy 17mm hex head eliminating the need for a special allen socket.
