Help with strange scraping sound
 

While off-roading this weekend the '95 Wrangler developed a slow
scraping sound that sounds like sheetmetal edges rubbing past each
other (low pitch). It happens only while going downhill and braking
with the engine. It happens in and out of 4WD and on paved and unpaved
roads. Nothing seems to be hanging on the driveshaft. It sounds like
it comes from the center of the Jeep but it is hard to pinpoint. I'm
suspecting something related to the clutch or transmission (can these
things make such a sound?). All shifting seems to be fine. Also the
noise does not happen when braking with the engine on the flat. Any
ideas are apreciated.

Thanks

Exhaust hitting something, due to bent exhaust or worn motor mounts. Please
me know what it is, because I have a '95 Wrangler too. ;^)

Re: Help with strange scraping sound
 

I would be checking out the drivers side engine mount. When it breaks
the exhaust can hit the front axle when decelerating.

If that is the problem consider chaining the replacement.

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:

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.

I couldn't find aftermarket.

Re: Help with strange scraping sound
 

Just an update. Replaced the driver's side motor mount last weekend
and while down there noticed that a bearing cap had fallen off the
front driveshaft u-joint at the transfer case so ended up replacing the
joint too. I'm hoping this will take care of the noise. I'll be going
off road this weekend for testing!

Thanks again.

You should replace all mounts (usually 2 on the motor and one on the
transmission) because just replacing one puts the motor at an odd
angle.

Missing bearing cap will most definitely make a noise. Glad you caught
it before the joint grenaded.

Re: Help with strange scraping sound
 

Happy New Year to everyone!


Well, the noise still hasn´t gone away (seems it wasn't the engine
mount nor the u-joint). It sounds like a slow metalic scraping
seeming to come from around the bellhousing area. It happens only when
using engine compresion to control speed when going downhill. I've
hear it now in 1st, 2nd, and 3rd gears at various times and speeds. I
can make the sound stop by giving is a bit of gas or by pushing in the
clutch pedal. The strange thing is that it does not seem to affect
anything else, Jeep shifts ok, clutch operates smoothly, etc. Any more
ideas? Any tests I can do?

Thanks
