T-case Mount Replacement

Hello everyone,

I've got a bad T-case mount (rattling on take-off) so do I need to just replace it or tighten it?

I'd love to just drop the whole thing and find out myself but I figured I'd poke around on here for a relatively decent answer.

I've dropped the tranny twice so I can do it but if it's a pain in the *** I want to know ahead of time to schedule out some time to do it. My only transportation at the moment.

OR, if it's too much "fun" I will just take it to a shop for a little when I buy my motorcycle here soon.

Any suggestions?

Trans mount or an exhaust pipe hitting somewhere ? There is no tighten for the trans mount, if it is failed, you replace it.

According to the National Shooting Sports Foundation, AR-15 sporting rifles account for nearly 20% of all U.S. firearms sales.

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

The t-case is securely bolted to the transmission...which is where the mount is. There is no t-case mount.

Thanks for the sig line

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.

This^^. And do yourself a favor and look at your engine mounts, too.

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...

Thanks for the input guys.

Check your motor mounts also. Usually the motor mounts go and they take out the transmission mount.
