Best Way To Identify Idler Hubs On 18' Utility Trailer
Updated 08/04/2026 | Published 07/31/2026
Question:
Hi I have a 18ft utility trailer, i am changing out the 10 inch rotor and and calipers, I have 3 idler hubs that are the same , my new 10 inch rotors fit fine. 1 does not . The center that the rotor slips on is too big, it looks like they cut the center of the old rotor out with a saw. I would like them all to match How do I determine what idler hubs the other 3 are so I can buy a replacement?

Hey Allen, welcome back. The best way to identify your idler hubs is with the casting number. Idler hubs should have a casting number on the back. It is typically a series of 4 digits like 8-248 for example.
Shoot me that number when you get a chance and I'm happy to help identify your hubs and get your another one.
What kind of trailer is it? When was it made?
