My drivers side power seat slides back and forth about 1 inch. Does anybody else have this problem and know how to fix it.

 

This is a common ailment on the Gen1 Durangos, mine included since the early days. I should have had it fixed under warranty but didn't. You can read about this problem on many Durango forums. There is a posted repair here: http://www.craigcentral.com/durango/seat.asp
