Annoying clicking noise - Diesel Forum

I posted earlier about an annoying "clicking" sound on my truck that occured while cruising at about 50 mph and up. At the time it seemed to be coming from forward of the cab and was engine RPM related. I wanted to try and figure out where this noise was coming from before I took it back to the dealer so I could point them in the correct direction. I beleive I found the problem. The "clicking" sound is coming from the manual 4x4 transfer case. I can stop the clicking by pulling slightly back on the 4x4 manual shift lever while going down the road. After I release the lever the "clicking" sound returns. I don't have any experience with transfer cases but I know a clicking or buzzing sound from manual transmissions was usually caused by a bearing or a "bump" on the slider where the fork contacted it. Anyone know if the fork, slider is the set up used on these manual transfer cases? Also as I go down the road and put my hand on the 4x4 manual shift lever I can feel a high freq. buzz. Will one of you guys with manual 4x4 let me know if yours is the same? Thanks.

mine does nothing, very quite and I really don't get any buzz with the hand on the lever either.
