Thanks for the response. I looked for the work order that was done for the transfer case, and i didn't get one. i have one for the other work that was done on the car at the same time, but not the transfer case. I remember signing the work order though and seeing it, but like i said it was covered under warranty by isuzu. The cost of the transfer case was $2,000. and they gauranteed the new transfer case. The only "symptom" that preceeded the transfer case change was that the center consoul would get very hot, hot enough to keep coffee warm..lol.
Look forward to other responses..glad i'm not alone with the clunky sound when shifting....looking for input on brake noises too.
Thanks!!
