Question:

I purchased Hubs, Bearing and Seals from you and installed according to the video on my EX Lube axle. When I greased for the first time, I was pumping until I could see grease coming out the front. It never did come out the front, but instead started coming out the back. I have not yet pulled the trailer, but am concerned that the back seals I purchased are leaking. Any insight would be helpful. Thanks.

Expert Reply:

If you have grease coming out the rear seal, you have a bad seal or the incorrect size seal size. The EZ lube spindles will allow you to see grease out the front with the rear seal intact if your seals are working properly as you stated. I've attached a video of the installation of the EZ lube hub # AKHD-545-35-EZ-K to help.

I have a 3500 lb axle on my boat trailer. Recently replaced a hub and re greased it with marine grease with no problem. I got back from a trip and went to regrease it and grease is coming out of the back. Is the problem with the hub or the EZ lube system? What do you recommend I do?

It sounds like a bad/damaged seal as mentioned above. Did you verify that you have the correct size for the hub?

@ClaytonC: I've replaced all my seals 3 times now with different brand seals. All the proper 1.719x2.565 size for the #84 spindle. They have leaked every time. The EZ-Lube design appears to be bad. Puts too much pressure on the seal I guess. Just have to re-pack the old fashioned way...
