Howdy Folks,

90 2WD

Has anyone seen a situation where a rear axle nut ( with cotter pin in
place ) becomes loose ?  I had to tighten it down about a year ago after
hearing what sounded like dragging  squeaking brake sounds from that
side of the car. It appears to be loose again as I am hearing the same
sounds when driving, so I am wondering if this is due to worn bearings ?
Obviously the nut is not turning but what else could explain this ? The
wheel , with car raised turns fine with no binding or what I would
assume would be a shot bearing , I pulled the drum and the brakes are in
order and not causing the noise nor is there a lot of play in the wheel
when grabbing and rocking it so I am puzzled.

Any ideas on this are appreciated.
