Folks,
    My sliding door is rattling when closed when I go over large bumps.
When I open the door and shake it from side to side, I can get it to
make approximately the same noise.  It seems as if the roller bearing up
on the top of the door (the one that keeps the door in the top channel)
has a diameter that is too small.  It can rattle back and forth.  Do
these bearings wear out on the outside?  and will changing that bearing
solve the problem?  I've checked in the archives and can't find the
answer.
