When I hit a small pot hole it feels like the drivers side rear end bottoms out. Struts and springs are fine. What could it be?
if the sounds is like a "cling cling" of metal knocking... check on the sire of your caliper... lots of montana/relay/uplander/etc. has this problem... the holes in the caliper when the sliding pins goes become loose and on each little bumps you will have a little "cling cling"... I know really annoying :-)
