ive heard from a neighbor that it could be a bearing in the transfercase, anybody hear of that before?

 

Was the noise like this?


I replaced my transmission mount and it still makes the noise when I accelerate.

 

no only does it when i hit the gas, nothing while idling or sitting.

 

Dude TAKE YOUR INSPECTION COVER OFF! Your Bolts on your flywheel are loose!!!

 

I get a similar noise in my 98'. It makes a noise that sounds like someone in the next room using a hammer drill on a concrete floor. (best I can describe it). But it only does it while climbing a hill or accelerating between the speeds of 53 and 58 mph. Never at any other speed. As soon as I let off the gas or push in the clutch it goes away. Also, it doesn't matter if it's 3rd, 4th, or 5th gear, and doesn't change frequency with engine RPM. It sounds like it is comming from somewhere forward of the firewall. So I figured it must be drive train related.

 

skeletool:
mine did the same thing but between 30-35 and it ended up being a driveshaft u-joint not sure if its the same for you but worth checking because if it break it sucks sittin in a parking lot waitin for your uncle to bring the trailer ha

 

Motor mount.

 

Not Bad at all... I did mine in about an hour when i was taking my time. Support the tranny, unbolt the old mount with the 4 bolts on the bottom and inside of the cross member. Then remove the cross member bolts and studs from both sides (the studs may break, so PB Blast them for a couple days). Then there are 2 18mm bolts the bolt the mount to the bottom of the T-case. Remove those and install the new mount.

Make sure you get 2 new bolts to replace the 2 studs you took out.

 

Good to know. Was yours the front driveshaft?

 

Standerd or Automatic, if standerd the sound is most likey your throw out bearing.

 

bottle jack and a few bolts not real hard.

 

Mine isn't like the Youtube sound at all. It's intermittent when I accelerate through first gear (auto trans), then it goes away.

 

I FIGURED IT OUT!!!!! It's the mechanical fan (not the electrical), scraping against the bottom of its shroud. The top of the shroud is bolted on, but on the bottom it just kinda hangs loose, so sometimes when I accelerate the bottom goes back and the fan scrapes it, BINGO!!!!

 

glad to hear you found it

 

I did a 1" TC Drop this weekend, and it took care of the noise.
