Maybe it is a "weakness" in the 2002 model year
Mine just started it lately and now it is really getting bad.....like every rest stop (for us that is about every 3 hours). I take out the hammer and pound it back down into place.
Needless to say it is not good advertising for Airstream that an owner has to do body work on the road.
I was serious about the LockTite. That product has worked on 3 of the 4 BAL stabilizing jacks. Number 4 (left/driver's side front hasn't gotten the message yet.
This is my/our first Airstream; it is quite a shock that it is the fix-or-repair-daily type of product--thought it would be the F-O-R-D
Sorry for your similar problem but do like to know I am not the one and only.
