I just had a similar experience with my =
'91 GL. It
turned out to be the CV joints in the rear. There was no grease (or =
whatever
lubricant is used) left in the boots. This noise was also more prominent =
at low
speeds and sounded like someone hitting the wheelwell with a hammer. =
Very
alarming noise indeed, and it seemed to come and go for a few months =
until it
got really bad. Hope this helps!
