Who has manual trasfer case (HELP)

[04wolverine]

DOES YOUR MANUAL TRASFER CASE MAKE NOISE??????I have a 2004 chev 1500 4x4 with 4 :10 gears and a manual trasfer case. I have had it in to the dealer twice now with the complaint of transfer case noise. It sounds like a bearing wearing, sometimes almost like the sound a throwout bearing makes on a standard transmission when it is about to go out. It gets worse when hitting bumps or after a long drive on the highway. It is not overly loud but annoying as you can hear it all the time wether coasting in neutral 4 low 4 high or 2 wheel drive. The dealer keeps telling me this is normal noise for the manual case but I dont believe them. My warranty expires in 3000 miles . I serviced the t case and checked for leaks with none apparent.

 

Any suggestions???

 

Thanks guys.
