I am in the process of adding disk brakes to my Venture/Tri-Wing Trike and have a question. When I pulled the axles I discovered inner grease seals which are not on stock Mustang rear ends, and the wheel bearings were dry. I called Tri-Wing and they said I should leave the seals in and just grease the bearing with RED stickey grease. They said they have had rear ends last for 100,000 miles doing this. This just doesn't seem right to me. Has anyone else run into this problem?
