I put a 6" superlift on my truck and I'm getting a driveshaft related noise (I think) :confused013: My question is, am I the only one with this noise and this much lift?

hey O having that same problem with just 4.5 can't figure it out my self. took it to the dealer and now they say i no longer have a warrenty on my drivetrain *asterds

I guess a custom driveshaft may be in my future.

No your fine im running 8.5 in lift and stock driveline just turn your axle so there is les angle on the front driveline, i think its positive camber and mine is turned as far as it will go and my noise went away

Did you install the drop bracket for the trans? Do you have a 2 piece rear drive line? If so, did you shim the carrier bearing down. You wont need a new front shaft but maybe a index ring from Spirson.

Well he has a mega cab so its a two piece rear drive line so he should of got a shim for it. And make sure you put the rear blocks in right since there angeld for the rear drive line. Just turn your axle up and you should be fine.

i think i have the same problem, but not sure if its coming from the front or the back or both. im leaning towards both, sometimes it sounds like its right under me then others towards the back, ive been meaning to take it to where i got the lift to see what they say but havent had the time. ive had a couple people tell me they think its the U joints but idk

I have a one piece rear driveshaft. And I'm trying to get 4wheelparts to tell me if there was a transmisssion drop bracket installed. I compared it to the one on my 4500, and they look pretty much the same?!? I'll wait for a call from them to confirm.

and won't turning my axle up throw off the alignment? Doesn't that change the caster of the front axle?

Oden,
I have a 6" lift and was getting a noise/vibration at hwy speed. The rubber boot that covers the splines was tight and not allowing the drive shaft to extend freeley.
I had the local drive shaft extend the shaft 1 1/2 inches, that did the trick.
