Ok so as im accelerating at a medium throttle, around 50 to 55mph i start getting a violent shaking so bad that my passenger seat moves left and right about 2 inchs or so and the entire jeep shakes too. now ive allready rebalanced the tires, gave it a new allignment (on a laser alligment machine not the old tape measure trick) and toqured the wheels down to spec but it still happens. I think it could be a bent rim or two or four lol but im not to sure. I was hopeing if anyone had this issue or knew of something like this happening? Thanks for the help in advance.

is it lifted? if so you need a SYE because you driveline is at a severe angle

sorry i failed to let you guys know that it isnt lifted (yet) its still stock height which is why im puzzled. I've been "mudding" with it before and hit some nasty holes so i may have bent something but last time i went was atleast four plus months ago.

check drive line ujoints.

check all your control arm bushings and your trac bar, along with ujoints and balljoints

i just replaced my left front u-joint last week and im working on getting the other one replaced aswell. i just had the truck on a lift in school and didnt see anything bent or any torn boots/bushings. and when the alligment was done the only thing out was left outer toe. so it probably is that u-joint in the front that i havent gotten to yet lol my other one came out with broken caps and that was the better of the two oops.

make sure u clean out your rims after mudding cause of the mud can off balance the tires

The u-joint that was removed.

Could be a belt let go in one of your tires. Look for a telltale malformation in the sidewall. I've had this happen and it behaves very much like DW. Look especially at a tire that has been plugged.

that happended to me before but ive been driving up and down rt 1 for 9 months now and havent gone mudding in awhile, i did an allignment last week at school and all numbers were green. all the rims have been clean for months now

i have noticed a few bubbles here and there on the tires i plan on replacing them as soon as i can afford them but i dont think that would cause the entire jeep to shake as much as it is now.
