I hae a bad shake after the body lift was installed. It feels like its in the drive train like unbalanced tires or driveshaft, also a U-joint. Help me out what could this be. It does it at highway speeds 50+ i made i video

 

Stand by I am thinking about what could be the issue ...

 

which is??

 

he wouldn't know he's layin frame

 

It happens only when you left off the gas going 50mph +? It is not the transmission. I am thinking it is in your front end right now.

 

on and off doesn't really matter. It's more noticeable. It's not the trans i know for sure its not. I have full power just a shake

 

It did not vibrate at all before the BL? That is weird. My old Ranger had a tweaked (slightly bent) rear axle that would only cause some vibrations going 55+. For some reason I am thinking it is in your front end. When the last time you had a good alignment, balance, and shocks?

 

if it was in the front end, i would think you would get alot more vibrations though the steering wheel

 

Did you check the u-joints good?

 

going to have the alignment and tires balance checked tomorrow and go from there. The Muffler output turn down was rubbing on the drive shaft made some light scratches not super deep but left some marks.


Nope, not laying down in the snow lol


its gotta be in the back. the entire cab shakes the seats really shake

 

Did you post some pic of your tires wearing funny? Like the tire threads were stepped.

 

Could it be the driveshaft? Maybe they hit it when they were installing the lift?

 

Those where my old tires, These a different ones

IDK how they would hit it

 

TRE's/BJ's? Could also be caster, because you put bigger tires on, it took it out of stock caster.

 

That was me.

 

I honestly don't know what that could be but when you find out please let us know. Just go over the whole drivetrain and suspension and see if anything is out of whack.

 

It bet that it has nothing to do with the body lift.

Did the shop take the tuck for a test drive after the lift was installed?

It seems like the issue lies in either your tires/wheels or your drivetrain somewhere.

Check all of your rims GOOD to see if there are any possible impact marks.

 

Seems like everyone has hit all the areas. Also check your body bolts to make sure you made them really tight.

I know it sounds dumb but I know by cab shook alittle at highway speeds and would make a loud bang if I hit a big bump after I did mine because the bolts loosened up so much. I even used the lock tight and mine loosened themselves up alot after I first installed my body lift, one even almost half the thread on the bolt!

 

Driveshaft/ U-joint test:
While driving, Throw your truck into neutral and coast, If the vibration changes, its a u-joint.

 

It started after body lift right? Id bring it back to the shop and tell them whats going on.

 

vibe is still there same strenght. i cant think of anything that would cause the shake from just a BL ill check the bolts but it didnt shake before

 

do you have packed snow in your wheels? if you do, get it all out. my shook like a bitch after this day

 

hahaha i did today took it all out with a propane ice melt-er from 4 feet away

 

The aerodynamic stability of the vehicle has been compromised. Lol

 

Still shaking?
