My LH axle is leaking around the seal. Not alot, but enough to annoy. This seal lasted ~2000 miles before it started to leak. There likely is a groove worn into the axle right where it meets the seal. I've heard there are sleeves available in the aftermarket meant to slip over the axle to cover any sharp edges or grooves, and thereby protect the seal from abnormal wear. Has anyone ever used such a sleeve? If so, was it easy to install? Please relate your experience(s).
