vibration after lift.

So I just installed bielstein 5100's and toytec 3" lift coils and light racing UCA's. I had them set on the highest setting. While taking the truck to the alignment shop there is now a very noticeable vibration starting at 50 mph. The alignment shop landed replacing lower ball joints, new cv axles, and new tie rod ends, plus the alignment which they said is spot on. They test drove it, and still has the vibration. They then lowered the springs to the lowest setting. I measured the lift and now it sits at 2" of lift. But, the vibration is still there. Any suggestions? thanks for any help.

 

See my post in your other thread

 

So just to be clear, you now have the 5100s on the lowest setting? That's good. You can go the next setting, but any higher than that is a big no no. Are your vibrations coming from the front?

 

coming from the front, never had a vibration before the lift. its on a 99 Tacoma.
I read your post on my other thread. What is meant by preloading the spring? And what can I do to correct it? sorry for the dumb questions, but this is all new to me.
