    My right rear hub seal is leaking and my right rear wheel wobbles/hops at roughly 50mph. is the wobbling wheel causing the seal to leak? and is the wheel just out of balance or is something wrong with the hub that is causing both the wheel to wobble and the seal to leak?

    thanks

    Your axle shaft is probably bent, which wore out the seal. You can get a new axleshaft for about $100 new or cheaper used, and seals are cheap too.

    If your axle is bent it most likely is a SF.

    Although I have a 12Bolt rear, I had this problem about 4 months ago. It turned out to be the outer axle bearing. I rented a slide hammer at the local parts store and swapped the bearing out. In the end I had to replace the shaft due to the fact that the ruined bearing had started grinding away at the axle shaft and it was out of round. So, rented and replaced the bearing, and seal 2x and the axle shaft once. I hope this helps.

    maybe your wheel is out of balance and your axle seal just happens to be leaking?? I dont think the hub bends easily on those axles, no experience or proof though.

    I have a friend who had the same senario happen to him. The inner wheel bearing on the hub went bad to the point that it wallered out the inside of the hub not allowing the race to stay where it is supposed to and also ruining the spindle on the rear end. Very expensive to fix so he just swapped the whole rear out for another.
