Bad Shake after body lift

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

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.

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?

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.

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?

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

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.
