To install race seal without damaging axle housing, use ABN Bearing Race and Seal Bush Driver Set with Carrying Case – Master / Universal Kit for Automotive Wheel Bearings. To use, simply select the correct bushing, align straight and centered, and then pound in/out. They are reversible, so if you aren't familiar with installing, turn a larger size backward and put in a flanged seal. The solid, knurled handle offers extra grip and control during use. This set includes 1 driver and 9 collar/discs: 1.565", 1.750", 1.965", 2.325", 2.470", 2.555", 2.830", 2.995", 3.180". The collars fit standard race sizes used in most wheel bearing applications, and the aluminum construction won’t mar the bearing. This set comes in a carrying case for easy transport, simple storage, and quick organization.
