ok so i have a 1991 jeep cherokee and ive been having a crazy shake on the driverside on the highway. i have just dropped it off at the mechanic to take a look at the u joiint he called back said he drove my car at highway speeds and go no shake and he was checking my tire balance. I have had my tires balanced like 4 times already i know its the ujoint but when he looked at it he said it was tight so idont know what the heck it is. Am i crazy?

 

Is it after you hit a bump that it goes nuts?

 

no just driving sometimes it even happens at like 35 40mph

 

u my friend may have fallen victim to the infamous death wobble. everytime i tried to show some one my death wobble it wouldn't happen whenever i didnt want it to happen. you guessed it. it'd start shakin n seizuring till i pulled over n stopped.

 

i dont have a lift. Can it still happen?

 

unfortunitley yes it can. mine happened when i lifted it and was actually cure by bigger tires and a balance but i've heard of hundreds of different ways it can happen. everything from bald tires to worn bushings

 

Ye sit can..

Lift is not required for "Death Wobble" to happen.

Start by checking tie-rods, Control arm bushings and the track bar. If you don't find a issue start with the unit bearings.

I've never seen a u-joint cause a vibe at a set speed. They either vibe or not...

 

hmm when i bought it it never happend and then it just started getting worse. i went to another mechanic and he said i did have a little play in it but everyone else i went to didnt see it

 

so when the mechanic calls back what should i tell him?

 

I'd say to start by doing a complete front end inspection..

The sad part is most times you end up just replacing parts till the problem goes away..

 

first time my wobble showed up i almost my pants. i was cruisin along at like seventy five, i had my lift in for about a week and out of nowhere the truck shook so bad i couldn't do anything but hold on hit the brake pray i could bring it to a stop before it rolled. crossed three lanes and ended up skidding to a hault in the shoulder. took me a week to figure it out cuz it wouldn't do it if there was anyone else in the car

 

ya i just got rid of the rear shacking by repacing the driveshaft u joints. now when they do the inspection should i tell him like a certaint thing to look at? sorry for all the questions

 

your track bar,arm control arm bushings

 

see mines not that bad i can drive it while it shakes.like im doing 65 and its shaking but its still drivable idk what it is! lol its so annoying

 

yours probably is not at as bad as mine cuz its probly from parts wear. i had a one tone come along repositioning my axle for my lift five days prior. either way good luck on gettin it fixed i kno how much of a hassle it can be
