Trailer Hubs Leak Oil After Installing New Seal

Updated 10/08/2019 | Published 10/07/2019

Question:

I hace a 22gn 10000 lbs axles. I have a problem with torquing I think. I replaced the seals and next day they were leaking again. What to do or how to torque the spindle nuts? Any specific torquing? Also the oil caps get loose regularly. Thank you for your help.

If you have oil leaking from the rear of the hub then that would indicate you either have the wrong size seal, you are over torquing the spindle nut, or you just have too much oil. I recommend you use the serial number on the axle that way you can reach out to the manufacturer to confirm you have the correct size. The spindle nut on most axles will be torqued down (Usually 50 Ft. Lbs.), backed off, and then tightened hand tight. There should be a fill line on the oil cap to go off of.

If you have oil leaking out of the front of the hub then odds are you just need a new oil cap/o-ring, the Replacement Oil Cap Kit part # RG04-270 should work.
