Hi Larry,

Concentricity in the stub axle seems like your problem.  It may be bent
from a bad curb hit.  It might be a marred sealing surface allowing water
and dirt inside the bearings as well.

Also make sure all the old grease is removed and cleaned out, and new
high-pressure grease is used.  Mixing greases can have a bad effect.  I
use STA-PLEX red extreme pressure grease.  The load ratings are great and
it is water resistant.  High temperature too of course.

The way I torque the rear nut is to stand on a breaker bar.  I know my
weight (180 lbs) so I stand at a 2 ft radius with one of my feet on the
bar, this gets exactly the required torque.  I steady myself by holding
onto the rain gutter.

Hope that helps,
Ryan
