As the title says. I think i have a stretched tranfer chain. My ute makes a horrible sound when its in 4wd but only when you make it work like if its bogged or going up a slippery hill or if i let it idle along and hold the brake on it does it. What can any of you tell me about it as i dont no a lot. I read on here about putting a d21 tranfer case in as they have stronger chains or somthing. Is a straight bolt in job. I have a 05 d22. Or will it need other things modified to fit a different transfer case Just trying to find out as much info as i can before i take it back to the mechanics. Ill try and upload a short video where you can hear the noise.
