[QUOTE="Bob McDonald, post: 982369, member: 54868"] I have absolutely no 4wd experience, so take these comments as from a novice. First, you didn't say how shafts failed, so I may be completely off base. It sounds like the problem is not the shaft, but either it the front diff. itself, or the transfer case Since you say that it was a lot noisier when you last had it together than it was when new makes me think the problem is in the front diff. and not the transfer case. but what do I know. There must be something putting pressure on the shaft when it is installed. Did you have some maintenance done to either the front diff, of the transfer case? Any chance that wrong parts have been used? mis-match of gear sizes or ratio? Just guessing here mind you. Good luck with it and let us all know what you find out. [/QUOTE]
