Rear vibration issue

I had the TRD lift installed on my 2022 TRD OR MT shortly after I took delivery. I began to notice a vibration in the rear after it was installed. I can see my bed shaking when this occurs. I’ve also noticed the shifter shaking while this is going on. Begins to show up around 50mph. Dealer claimed it was out of balance tires and stiffness from new shocks should be expected. Had the tires balanced per their suggestion and it did not solve the problem. Truck was returned to the dealer and I’m waiting to hear back. Still running factory duratracs. Has anyone experienced an issue similar to this? Thanks for any input

 

Hopefully they can figure out what the screwed up!

 

If it were an out of balance wheel/tire you would have had the vibe before the lift.

What is used to lift the rear? Spacer? How high?

Vibes in the rear aft lift usually caused by driveline angle. I don't think the TRD lift adds that much hight though.

Also "stiffness from new shocks"? What a line of BS that is!

 

1” block in the rear. OEM TRD shocks replaced the factory bilsteins.

 

Yeah pretty hard to screw up there eh.

 

You’d think. I overestimated the dealers ability to install a lift
