Question:

I am trying to find a bearing kit for my trailer. It is a 2008 American hauler night hawk auto. Model number NH8524TA3. Would you be able to tell me which kit I need. All my bearings numbers are worn off or not legible from what I could see. Is there somewhere else I can look then the bearing itself? I also see no number on my seal.

Hey Nathaniel,

If the part numbers wore off of your bearings and grease seal then you'll need to measure the spindle and hub bore hole in order to get the inner and outer diameters to identify what you have. To do this you'll need a caliper # PTW80157 and measure points B, C, and D from the diagram below. Once we have these measurements we can find the correct replacements.
