Question:

I have a 10k oil bath alko axle. I am not familiar with the unitized style seal. How do I remove it and replace with new? I have worked on many grease lube axles I just want to make sure that I dont destroy a 20 dollar seal. Thankyou

Helpful Expert Reply:

Unitized oil seals such as # 10-63 for example are different than regular grease seals. Unitized seals have an inner part that stays fixed to the spindle on the axle and its outer case rotates with the trailer hub. You would remove and reinstall a new one the same way you would with a regular seal.

The best tool to use for unitized seals is a seal removal tool which you should be able to get at a local auto parts store. Once you pry out the old seal, place the new one in the hub. Use a block of wood over the seal and gently tap it into the hub until it is flush all the way around.
