Horrible vibration not normal!! Need help!

I was pulling up to my house last night and outta no where the truck started vibrating extremely bad so I stop. I take off and hear a squeaking nose and can't locate it. I can drive for a lil and outta nowhere it starts vibrating bad, the passenger seat is shaking front to back horribly and I can barely hold on to the steering wheel. Im usually good with this kind of stuff but I can't find anything out of place or unusual. Please help

 

Damn....could be anything. Something has definetly come loose. I had a spring perch break loose from the axle tube once on a Jeep that did this. The whole vehicle was shaking & vibrating....bad thing is, the break point was hard to notice.

 

First easy check to do is, check your U-joints and inspect you rear driveshaft for lateral play. Your center support bearing is housed by a rubber bushing, so it should have a little play to absorb some shock.

 

Is your truck lifted or does it have stock suspension?

U-joint?

 

I looked at that. How much play should it have exactly? I can move it what I think is quite a bit but this is the only vehicle ive had with a carrier bearing, im not sure if its the rubber moving or thd bearing in the rubber

 

Yes I bought it with this stupid lift already on it a few months ago and im waiting for my mid travel to show up already lol. The bearing is spaced down im guessing to help with the driveline angle cause of the lift

 

from what i've read from previous threads, this could be a "death wobble"?

 

Couldn't tell ya how much play the bushing has right off the bat. The best way I could tell ya how to check if the center bearing has play is to jack under where the U-joint is to support the shaft by the bearing then grasp the other side to see if it has any play. I don't know any other way to do it with out disassembling it. I just checked my bushing play and it has about .25" of up and down play, and maybe .175" side to side.

 

Well thats a good way to explain it. Do you know the culprit of it?

 

I

I think mine might have more. ill check it better when I get back from lunch and let you know how much ive got. Im thinking about putting it on jack stands and running it to see if i can find it but im scared if it shakes like it did it might fall off

 

thats not death wobble. death wobble is when a vehicle goes over a surface and the vehicles steering/suspension cannot get it to recover from uneven road surfaces. more common in jeeps/chrysler

 

Yea I know what it is. I know this isnt it but its a damn good way to explain it

 

I bet center bearing. When it went on my old truck there was like 5" of "play" I can't believe the drive shafts didn't fall out.

 

For safety, on as flat of a surface as possible, put the jack stands under the rear axle as close to the leaf springs as possible. Chock at least one of the front wheels with blocks. When you put the trans in gear, only put it in 1st or reverse just in case(highly unlikely though) but just in case it does come off the stands, it won't go that far. Even better, is to have a second person to ease on the gas, at that point you can have the trans in D. You can hit the gas with your hand and look under the truck at the same time to see what's going on. Other guys have strapped a camera under the truck to see and hear what's happening, and there are U tube vids of this as well to cross reference. The jack stand method is never recomended, so use your own discretion, and please be safe. Post a vid if you can.

 

skip to 1:05 this is death wobble:

Im going to put it on thd frame lift at work and my friend is gonna help so ill let ya know what I find out

 

Just get under your truck, grab the drive shaft and shake it. If it moves more than a very tiny amount.....welcome to the center bearing replacement club.

 

Yep just joined lol and it already got more play then it had earlier. Any idea what they cost
?

The dealer wants 206 dollars! is a one piece drive shaft worth the extra hundred bucks to not have to have this problem again?
