Using Old Bearing Numbers to Find the Correct Replacement Bearing Kit for an Interstate Trailer


Hi, I am looking for a replacement bearing kit for a 2008 dual 3500# axle with greaseable spindles, enclosed trailer, model # 1714TA2. I did some research and it looks like kit BK2-100 is the right kit. I tried to get some specs from Interstate bought trailer used but didnt have any luck. Could you point me in the right direction? Thanks.

The best way to find the correct replacement bearings is to get the numbers stamped onto the metal of the inner and outer bearings that are currently on the trailer. With those you will be able to find the correct replacement bearings, races, and seals. If you find that the outer bearing number is L44649 and the inner bearing is L68149, then this is probably the correct kit. You will also want to check that the seal has an inner diameter of 1.719 inches.

I have included a link to a video on inspecting trailer bearings that should help you when removing the old bearings.
