did you have it aligned?
do you have a SYE?

the lack of either one of these at that height will tend to cause a very large amount of vibrations.

the hitting the bump and tires chirping is due to you not having an alignment. also did you get an adj tracbar?

and i hope by you saying you dropped the trans you meant transfer case.

ok

yes i droped the transfercase and it shook and chirped before the lift i was hopping with new lower control arms and bushings it would help things. yes i put a new trac bar in .. im not sure about the alignment because all that changed was the caster so it would make the steering touchy not throw the front end around .i gess im going to changed all the ball joints and tie rods and hope that fixes it..

With the stock steering system, when you raise the body in relation to the axle without aligning the front end it will toe the front wheels in. That is why an alignment is required when a lift is installed.

Get the alignment done, then start replacing parts if it still has death wobble.

You need to get ALL your front end parts in good shape, and a professional alignment BEFORE trying to track down death wobble (you may even find it is no longer an issue).

Excessive caster can cause problems as it also effects DS angle. According to the FSM, proper DS angle has precedence over caster angle. Acceptable caster is 5* to 9*.
