After my output-shaft snap ring let go for the second time and was replaced, I now have a banging noise coming from the transfer case when in 4wd. It sounds like it's kicking in and out of 4wd violently.
Does it in high or low range. I took the case apart and everything looked OK. Even took it to a friends big-rig transmission shop and he said it's OK.
Would the linkage adjustment cause this sound or do you guys have any suggestions?
