Clunking noise fron transfer case?

I posted a couple weeks ago about what I thought was a rear end noise that we had narrowed down to the rear upper ball joint and/or control arm. I've had the vehicle at the shop this week & they don't see any serious wear on those parts & the rest of the suspension looks great right now.

They think it's coming from the transfer case (selec-trac model) since it can be felt from the driver seat. The bumping noise first occured going over larger bumps, & has gotten progressively worse to where it now grinds/clunks when you take off from a stop along with hitting smaller bumps. Any ideas? By the way I inspected all the u-joints & there was no movement, no missing retaining rings, no cracks, nothing but average wear. Thanks in advance for any advice you have.

hey i had the same problem with my 2004 wj... i took it to a shop and they also said it was the transfer case, so i switch it out myself and it still made the same noise...so i noticed my cross member was bent from playing in the mountains..so i replaced it and noises went away...another problem could be you rubber mount the connects the tranny to the cross member could be bad.. hope this helps

I´m newbie on GC world, and I´m afraid I need some help here... The rubber mount that goes between the tranny and the crossmember oj my WJ is miserable, but I cannot find this part on the service manual. Would you guys happen to have the part number of it? Tks a lot!

you talking about the transmission mont. go to rockauto.com and look up what year and what jeep you have then click on the transmission tab then tranny mount. take a look at the pic and see if thats what you are talking about. i also was wondering if it was supposed to be a solid rubber in the middle or if there was a gap any where mine has a gap i think mine is bad.

this is mine this what your talking about
