Question:

I am trying to match a alhub to my spindle. I tried your help line several times but have had no luck.

Expert Reply:

There are a few different ways to make sure that you are getting the correct hub to match your spindle like the wheel bolt pattern, bearings, and weight capacity.

You can either use a Digital Caliper # PTW80157 to measure the different sections of your spindle (see attached picture), or you can simply remove your current hub and locate the bearing, race, and seal numbers (on same attached picture).

Once you know what the measurements or numbers are you can either filter through our selection of hubs which I have attached or you can let me know and I can make some recommendations for you.

As an example, the spindle # TRU84FR which is more commonly known as a # 84 spindle has the following bearings, races, and seal:

Outer Bearing - # L44649
Outer Race - # L44610
Inner Bearing - # L68149
Inner Race - # L68111
Seal - # RG06-050 (I.D. of 1.719" and O.D. of 2.565")

This same kit is included with the Trailer Idler Hub Assembly # AKIHUB-545-35-K.
