Thank you for the reply. I am interested in removing and replacing the axle bushing, which is what the seal rests on. Maybe it requires a special tool to remove and install.If you are talking about the seals, remove the wheel and using emery clothe and shine the axle for the new seal to slide on. Using a drywall screw drive it in and rip them out, try not to lose any fluid and repeat on the other side. Before re-installing the wheel smear some anti-seize on the axle.
I appreciate the suggestion. That is definitely clever and thinking outside the box but the bushing has a metal seat behind it so you can't drive it in further.I'm not sure about your particular model but some have enough room to drive them in and add new bushing beside it. Is it worn to the point that the seal is leaking?
