Yeah, the pipe hangs just fine and the only time it DOESN'T rattle is when I've got in 4WD. So I'm fairly certain it's the mount. Unless there are some moving parts in the driveshaft that would need to be replaced?
It's just a really annoying noise that's driving me insane. Plus I don't want my T-case to end up on the ground some time soon
Transmission mount is simple to replace, just put two jacks, or jackstands under it, one on the trans, and the other on the tcase. Unbolt the Four nuts in the middle, then unbolt the four on the sides, two bolts, and two nuts with studs. Be very carefull with these cause they break easy. I would spray kroll on there ( its the best imo) you might want to heat them with a torch too. I just did this and broke one. Everything was fine until the last dang stud snapped, and now i'm going to have to either drill and tap, or take the carpet out and try and get it from inside the jeep. Not to discourage you but just soak it with kroll multiple times before you attempt this. After the transmission mount is out, the rubber part, that i'm assuming what is broke on yours is right there. On mine the rubber part was fine, but the metal trans xmember was cracked, but its the same steps to replace either. Hope u have better luck than me.
Oh and i didnt use kroll, was out, and used liquid wrench instead thats why it broke imo.
Hahahaha no problem man. I guess the threads I've been crawling must have been talking about the tranny mount. The sad thing is I had the thing down last summer due to a bad freeze plug in the back of the block. Should have just changed it then... bummer. I guess there's a weekend project! I just rebuilt the engine also but the engine mounts looked pretty decent! Granted that was only my eyeball opinion, so I might just go about changing them as well.
I'm a blaster guy though. Blaster, a propane torch, a big*** sledge, and the handle of a floor jack for some leverage on a wrench handle and you've got all you need to work on a Jeep lol. They're simple really...
