Spindle and Trailer Idler Hub For 2,000LB Trailer With 15", 5 On 4-1/2" Bolt Pattern Wheels

Question

Question:

I need to replace my spindles and hubs on a light weight trailer. My rims are 15 5 lug on 4.5, however the pilot hole is only 2.56. Which hub will fit this rim? I cant find pilot hole dimensions on your website for the hubs. The trailer weighs less than 2,000 lbs. Thank you for your help

There are two spindle sizes that are commonly used for a 2,000lb trailer axle. First is the 1" BT8 Spindle # TRU94FR that you would use with the Easy Grease Trailer Idler Hub Assembly # AKIHUB-545-2-LFEZ-1K. This hub has an outer pilot diameter of 2.47 which will allow you to use your 15" wheels that have a 5 on 4-1/2" bolt pattern and 2.56" pilot hole diameter.

The next is the 1-1/6" BTR Spindle # TRU44FR that will need the Easy Grease Trailer Idler Hub # AKIHUB-545-2-LFEZ-2K. This also has a 2.47" outer pilot diameter for your wheels.

Both hubs are lug centric so the difference in pilot hole diameters will not affect the fit for the wheels.

There isn't enough surface area on hub #AKIHUB-545-2-1K to safely mount and use a 13 inch wheel. The hub would have to be larger to properly support a 13 inch wheel. For a hub that uses the same bearings, can take a 13 inch wheel, and also has a…
