  • 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.

  • How Tight Should Spindle Castle Nuts be Tightened
  • The nut on the spindle should be tightened until snug, with no side-to-side play in the hub and then backed off slightly, about maybe a 1/8 of a turn. If the spindle uses a castle nut and cotter pin or tang nut, tighten the nut finger tight until it stops, then back it off so the cotter pin or washer tang fits into the next indentation of the castle nut.
