Transfer case questoin.

I have a 99 TJ with 2.5/auto combination. This is my first jeep and I am assuming that I can shift from 2hi to 4hi while moving. My old Durango was this way as long as I am under 55 mph. I know 4 lo is a different story but back and forth from 2hi to 4 hi is ok while at speed?

Yep the Wrangler's transfer case system is known as a "Shift on the fly" system and you can go back & forth between 2Hi and 4Hi at any legal speed. Just don't use either of the 4x4 modes, 4Hi or 4Lo, on paved roads if they are not covered in snow, ice, or mud. Pavement, even if it is wet from rain, has too much traction for the type of 4x4 system used in a Wrangler.

I figured so just wanted to make sure.

I have a rattle in my transfer case shifter and the guy at the exhaust place
(he's a pretty decent mechanic) said it was rattling were the rod that goes from the TC to the shifter links up. He said he thought there was a bushing in there and that it was probably worn out. Is this a simple fix and can I get that bushing at a dealership or what? When the jeep hits the right RPM it rattles and if I apply a little presure to the shifter itself it quits so I am sure he is right.
Thanks again.

hmm flyin lowe, I think I have the same problem too, but I dont think its my T-case. Sounds more like something in my transmission because as I slow down I hear that rattle but at high speeds or when im stopped it goes away. I dont know if its a bushing, but if it is it may explain my grinding?

Your mechanic is most likely right, a rattling transfer case shifter linkage is often caused by a bad shift rod bushing. It's pretty easily fixed but the skidplate does need to be dropped for adequate access to that area.
