How to Pick Out Replacement Trailer Bearings and Seals for Trailer Hub
Question:
I have a utility trailer Big Tex model 30SV 5x8 single axel 5-bolt hub. How do I know what bearings and seals it needs? Does etrailer carry the correct ones? The trailer is about 10 years old.

I really wish there was a way to determine what bearings a trailer needed without actually pulling the wheel off and checking, but there isn't. The only two solution I have for you would be to remove the hubs and get the numbers that are stamped on the bearing or for you to remove the hubs and use a digital or dial caliper to measure where the bearings and seal ride (see pic).
To pick out a replacement grease seal you will need to measure the diameter of the spindle where the grease seal rides with a digital or dial caliper and then need to measure the hub bore where the current seal rides. With those two dimensions we can pick out the correct seal that you would need.
I attached a link to a page that has all of the grease seals we carry. You will need to select your inner and outer diameter from the filters on the page and the correct seals will be listed.
With that info I can help you figure out what you need.
