    drivetrain \"clink\"

    Ok, my truck is an IFS... but from the tranny back its pretty much the same as a straight axel. I have a 350 with a TH700-R4 and a NP241-C transfer case. When I put the truck in gear I get a "clink" in the drivetrain. It does it especially loud when going in to reverse. Also, I have already checked the U-Joints... and they're nice and tight. Is this clink in the rear end, or is it in the output shaft? What would the estimated parts cost be to fix these problems?

    Thanks, Dan

    By looking at your bio, I see it is a '90 half ton. Sounds to me to be the rear. One way to check is to set the parking brake, chock the wheels, and put the truck in neutral with the engine off. Crawl under the truck and try to spin the driveshaft. Listen at the diff side for the mystery noise and also see how far the shaft spins. This will tell you how worn your rear is. Next you can put it in park and do the same thing listening at the t-case end of the shaft. Cost will depend on what's wrong.

    You might also check out the slip yoke at the back of the transfer case, it can wear and create some slop in the driveshaft that will make some noise. You might do a search on the main page using the word "clunk". You'll probably come up with some other good info to look at.
