k i was driving to a town near mine yesterday on a paved road that has a lot of minor bumps and cracks that stretch across the road. anyway i just came around a corner doing roughly 80km/h and hit one of these 3-6" across 2-4" deep cracks across the road and my jk stayed straight but the wheel shook back and forth and felt like my wheels were turning in and out repeatedly. the steering wheel itself moved side to side i don know roughly a inch or two.

i slowed down to about 40km/h and it stoped. now i notice on any bump my wheel does the same thing and u feel vibration in the wheel and the floor. the smaller the bump the less it does it.

for mods to the jeep all have done is installed the tf bb with rear tracbar relocation bracket and spidertrac 1.5" wheel spacers

what could it be thats causing it? steering stabilizer?

 

Check your torque on TB bolts and also your toe may have been affected on that bump, possibly something bent or loose. I would thouroly go over the trk bars and relocate bracket and your track bar mounts.

 

Also, check and see if a wheel weight was knocked off.

 

that sounds more like bump steer to me, deathwobble the first time it happens you know what it is because it scares the shit out of you, it's most often extreamly violent shaking almost to the point you have to pull over and ditch your underwear in the weeds after using your sock to clean yourself up

 

it don't feel like a tire is out of balance. everything seems tight aswell.

my bracket for the rear is in there tight aswell. the only thing that i had to mod was the tf bracket had its hole drilled in the wrong place which i stuck in a drill press and drilled it out.

like the vibration i feel in the floor and wheel after certain bumps feels like the initial wobble only minor like not as intense. feels likes the bump takes my wheel one direction and it try's to correct itself then goes side to side but very minor. im almost convinced after watchin video on utube that it was speed wobble/death wobble.

u ever see a bikes front wheel swing side to side at high speeds well thats what it felt like was happening, sorry best i can explain it and i seen a green jeep on there with it aswell and seemed to be what i was dealing with. i dont plan on taking it to the dealer right yet cause im gonna get the "u put a lift on ur vehicle so ur warranty is void" on w/e i need fixed.

like being such a minor lift and my wheels are stock im baffled. now im thinking maybe steering stabilizer but i have less then 19000km on my jk so it seems a bit premature for failure but not ruling it out.

and im writing all this with my iphone so if idont make sense or something point it out and ill elaborate on it

 

it was intense man believe me if it would have happened on the corner itself i would have been buying new haynes for sure. but thats the only instense one i felt. like everything was shaking harcore felt bad enough where if u were to keep driving stuff would have shook apart.

 

but i slowed down fast and it was over. now when hitting a bump i pay more attention as to see if i can feel anything and what not and it feels, on little bumps that is, that it "wants" to do it again just not quit enough of a bump to set it right off you know what i mean.... it happened/started last night by the way so i may not have hit a bump big enough to set it off again..

im a noob that hasnt experienced this before and its hard to explain it.

 

My wife's TJ was doing that, cross rotated the tires, it was gone, balance issue. Does it do it on every bump at any speed?

 

i have to be doing more then 30km/h and only bumps that are abrupt like if its a sinkhole in the road thats gradule but you still bounce or whatever it wont do it. but if its a bump like entering exiting bridge or overpass style bump it does it.

now i wasnt thinking it the wheels cause with previous experience it was a vabrition felt in the wheel and either all or certain speeds this is similar in vibration but the wheel wanting to shimmy side to side has never been experenced by me in outta balance tires and the first wobble was so extreme that that def was not tires outta balance

 

k well i am leaving work now i will try try and come up with better feedback of what i feel in the jeep so i can explain what is going on better.


thanks for the quik responses and help already though
