I have been fighting a leaking grease seal on one wheel of my 5th wheel camper for awhile now, I have changed the grease seal a number of times and I still wind up with that one wheel leaking grease on the linings and eventually that one wheel starts to squeal when braking and ultimately starts to lock up during low speed braking. I clean the linings each time with brake cleaner each time I have swapped seals The axle spindle where the seal touches looks fine no burrs or scratches. The only thing that's the least bit off on that wheel is the tire does show more wear on the inside, which probably means the spindle or axle might be bent? Could that be the issue? Ron W.
