Proper Bearing Replacement Based on Both Inner Diameter of Bearing and Outer Diameter of Race
Question:
I have a 2007 Thorobilt 4 horse trailer - the bearings have N markings but one broke so I need a pair. the interior dimension is 1.25, exterior dimension is 2. there are 5 I believe 1.25 ID bearings listed here and non have the ED listed - how do I be sure of fit?

Expert Reply:
With the inner diameter of your bearing being 1.250 inches, there are currently 5 options as you stated. The best way to determine fit is to find your race number or to measure your bearing race inside your hub. The outer diameter of that race will help us confirm the proper bearing fit.
For instance, if the outer diameter of the race is 2.441 inches, then we know the race is # 15245 and the bearing needed is # 15123. I've attached a photo to assist.
