Re: Help with strange scraping sound
Not really a problem like with the pre seventies cars would fail:
http://users.adelphia.net/~csudman/4...nt%20Broke.jpg and the
reason drag strips require engine straps. The Jeep is held within a
ring, so it may only fall enough to start to hit on exhaust/driveshaft:

Re: Help with strange scraping sound
You all must be psychic! The driver's side mount looks bad. The
rubber that goes over the top of the center bolt is mostly gone. I
recently put in a torque reaction bolt in the transmission mount that
had been broken before I bought the jeep. Looks like this mount had
been taking on that role and wore out.
Thanks to all who replied.

Replace all three mounts at the same time, motor left/right and transmission. If you don't the motor will not sit correctly and
your drive angles will be off.

The place I got my parts from is on that page.
I couldn't find aftermarket.
