Question:
Hi there, I am in need of assistance to a the correct replacement idler hub assembly for my trailer axle. The axle and hub have no markings on them. The inner race measures .999 and the outer race measures .998. I have a photo if that would help.

Hey, Harjot.
It sounds like based off the measurements you got, your race most likely is part # L44610 which has a 1" inner diameter and goes on a straight spindle. The next step down from that is race part # LM11910 which is 0.75" diameter, which would be way too small.
We have two different bolt patterns, 5 on 4-1/2 part # AKIHUB-545-2-LF-1K and a 4 on 4 part # AKIHUB-440-2-EZ-1K. If you need something that is marine grade those part numbers would be part # AKIHUB-545-2-G-EZ-1K or part # AKIHUB-440-2-G-EZ-1K, respectfully.
What kind trailer do you have?
