Vibration issues with Readylift SST kit?

So my coworker just got the Readylift sst kit 3/2 installed about two weekends ago on her 2012 Tacoma dcsb 2wd (base model I think) and after driving it at lunch today, she is experiencing vibrations when coming to a stop, very noticeable to where it feels like the front of the cab is shaking. The installer told her she did not need the diff drop spacers because it is a 2wd and not 4x4 so they only put on the sway bar drop spacers, strut spacers and blocks.

Is anyone else running this kit having this issue? Does she need to install a CB drop bracket? Would the blocks being installed backwards (tapered end to the rear) cause this vibrations?

I told her to get her brakes checked to make sure there is no warping of the rotors and her brake pads are wearing evenly. Also to make sure the calipers are tightened down good.

Any info would be great help!

 

The ReadyLift blocks can't be installed backwards if I'm not mistaken because they're the same length on both ends. (Not tapered) What does her UC arms look like? With 3" in the front, that could be a problem in itself. I'd also check the driveshaft out to see if it has an angle that would effect driving conditions.

 

I was a part of a thread recently where the OP was experiencing the same exact thing. It ended up being something installed incorrectly and IIRC, it was the blocks backwards. Let me see if I can find it.

As I remembered. The rear blocks were installed backwards.

 

Damn that might be it. I'll have to get down there and check to see if they're backwards.
