Is it Possible To Determine Replacement Bearings for Trailer without Pulling Hubs Off

Question:

Is there a way to determine what bearings, seals and racers i need without pulling the wheels off. What i want to do is have the parts on hand before i start the inspection for possible replacement. Please keep in mind that this trailer was under cover since 20098 and used about four times a year. we just purchased it and we take long trips so i want to be sure things are in good shape. thanks

If you can find out the brand and capacity of the axle we can most likely tell you what bearings you'd need. Otherwise you'd have to pull the hubs off to get the info.

Typical Axle Diameters Based on Axle Capacity
- 1,000-lb - 2,000-lb Axles: 1-1/2 inch - 1-3/4 inch diameter
- 3,500-lb Axles: 2-3/8 inch diameter
- 6,000-lb - 7,200-lb Axles: 3 inch diameter
- 8,000-lb Axles: 3-1/2 inch diameter
- 9,000-lb Axles: 4 inch diameter
- 10,000-lb Or more axles: 5 inch diameter
