Troubleshooting Leak on Trailer Axle

Published 07/14/2017

Question:

I have noticed some leak spots under the axial. It also gave off a smell like plastic burning the last time I used the trailer. What does this tell me?

Sounds like you have a blown grease seal on your trailer. This is a pretty common problem.

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.

If you have trailer brakes you will want to go over the brake components as well to make sure there isn't any grease on anything that might cause your breaks to not function properly.
