vibrating at take off

[towbeast03]

sup fellas, well I went through all the posts and didn't see it so I gotta ask....my truck vibrates when leaving from a stop. of course the harder I leave the more rattling happens. doesn't do it coming to a stop though. a friend said it might be the pitman angle in the front? or I have to change over to serviceable u-joints. let me know...thanx.....oh, 10inch lift on 37's btw.make a difference??

im on a 6inch lift with 38.5 and im running boggers and some shakin is definitely going on with the big tires. balancing my boggers is **** near impossible. best you can do is balance tires best you can and then retorque all the nuts and bolts on the lift kit if you havnt done that. make sure everything is squared away down there. and then start looking at other places on the truck if you cant minimize the shaking.

Sounds like your problem is your rear driveline angle to me. When you lift your truck that high. You also need to lower the rear drive shaft carrier bearing. If you don't you will get a vibration during take off from a stop. Almost all the lift kit companies sell a carrier bearing drop kit. Almost positive that's what your needing to buy and install.

Shim your carrier bearing down

True... alot of people don't think of this it will make a huge differance

I'll try that shim thing for the drive shaft...they're kinda hard to locate online anyone in particular carrying them??

Ford has them

Drive line angle (go to High angle driveline. com) they can build one with the measurements you provide. Also go with some re-greased or new Bearings in your whells and check your your U joints (torque to 17-20 inch plounds) so the bearings dont seize under elbow torque. hope this helps.

thanks for the advice guys...I looked today and my truck already has the drop shim spacer.... hey barney I'll give your idea a try next. I'll take a pic of the shim thing to show you guys. the angles of the drive shaft looks very straight....ya know when I was still in the market I drove an f-250 NEW, with a factory installed 8inch lift and that truck did the same vibrating that the truck I did end up buying does.hmmm....
