tranfer case or prop shaft?

[Reboosted]

OK got a clicking noise under heavy acceleration. Does not do it while turning. While I was trying to diagnose a highway speed vibration, I put a set of 315/35-17s on the rear (w-stock size on front) the clicking showed up on very light acceleration. I put the stock rears back on and the clicking went back to only on heavy accel. I did search a search and am kind of leaning towards a stretched transfer case chain. Am I on the right track? I know where a square body bravada is and was thinking of grabbing the prop shaft and x-case if its the right one. If its not the right one or I decide to mess with the stocker, how hard is it to replace the chain in these?

Re: tranfer case or prop shaft?

Don't know if this will help but I had a problem with different sized tires. I had all the same size but different brand tires front and back. There was enough of a difference in the size between manufactures that it put it in a bind. I tore cv shafts out as soon as it would hit 2nd gear. After 2 shafts I took it to the dealer who put a shaft in that I tore out in less than a block, finally figured it out and no problems since. Maybe look into cv shaft as well they make alot of noise.

The first time my stock propshaft went out on me it made clicking noises before hand... I honesty would suggest removing your propshaft and drive it around a bit. It's not hard to do or time consuming plus it'll help pin point your issue.

Re: tranfer case or prop shaft?

If I took the shaft out would it take enough of the load off the chain to make it not click. I have kumhos all around on the stock wheels, and it only clicks under heavy acceleration with them. Guess I could put the 315s (michelin) back on when I pull the shaft and see what happens. The bravada I want to get the xcase from still has its shaft too. Thanks for your input.
