I guess I am lucky because only my passenger side one tore up.
Same problem, too.
The braided wire tears up the wheeel that it rolls on to.
You can't fix it either!
I tried!
I cut the bad part of the wire off and re-built the whole spool assemble.
It tore up again after about two cycles of the window.
Ford sells the whole regulator assembl;y for $116.00
