  • How to Tell if a Trailer Bearing has Been Overheated and Needs Replaced
  • If the bearing is brown or black then that is a sign that it has been overheated and will need to be replaced. You will also need to replace the race. Replace all these parts on both sides of the axle at the same time. Only certain races can be used with a given spindle and hub so it is not likely there are ones that will fit without also changing either the hubs, spindles, or both.

  • Axle Replacement Recommendation for a Trailer with Unique Spindle Dimensions
  • The closest seal we have to what would match what you have would be the part # 168255TB. This seal has an outer diameter of 2.561. The inner bearing with the matching ID would be the part # 603049. Nothing we have would fit the 2.328 you have for the bearing inner diameter of the other bearing. Based on the dimensions you listed there really isn't any thing out there that would fit your spindle/hub. The only recommendation I could make would be for a new axle. I attached a page that...
