Lift Kit Issues

I recently had the Readylift SST Liftkit installed and there seems to be a small vibration sometimes like something might be rubbing. I can feel it slightly in the brake when slowing down and in the steering wheel. I can't see anything that's rubbing and haven't changed tire or rim size. At about 35mph you can feel it most and sometimes a humming noise nothing very loud, just a little annoying. The lift said it should maintain it's factory ride but definately different. Seems to be a little more drag also. Any suggestions please I would appreciate it. Thanks

 

its drivetrain vibrations somebody will chime in

 

Is that normal for the lift. Any harm with the vibration or is there any way to fix it?

 

sounds like a wheel bearing..

 

My coworker is having the same issue but hers is a 2012 dcsb 2wd base model. Is it driveline vibrations? Does she need a carrier bearing drop bracket?

 

Vibrations aren't normal, more drag feeling is.. you're altering aerodynamics.

Are you 4x4 or 4x2?

 

do you think the blocks were installed backwards (tapered side to the rear) and causing the vibrations?
