alright so a few weeks back my jeeps front drive popped off the front its all time 4 x 4 but now about 50 mph it was start weaving the lane if its bumpy road it will start a shaking bad shaking. feels like the whole front end is just shaking to death.its jacked up 4.5 inches.I didnt do the lift kit myself it was bought like that. any replies will be appreciated thanks!

sounds like you've got death wobble to me i personally haven't dealt with it in my jeep yet but it has been an ongoing battle with my ford truck id start by going through the front and seeing either if something is loose or what bushings have crapped out

Check all bushings and check your u joints in your drive shaft also check to make sure you didn't bens your driveshaft.

Don't forget your hub bearings. they are often overlooked.

Track bar bushings should be checked.
