scared the living shit out of me!

Background...

2001 Jeep Cherokee with 85k miles on the odometer

On the interstate heading home from my moms, light traffic, doing about 55 - 60 or so, hit a bump in the road, next thing I know

the whole front end is vibrating and shaking like there was a mini-earthquake under the hood.

The whole event lasted maybe 5 seconds before it smoothed out, but it was 5 seconds of white knuckle terror.

Looks like tomorrow will be spent jacking it up and crawling underneath to see if I can locate the problem, if

not... it's off to a mechanic and placed on a lift.

One possabilty... just two days ago I took one of my front tires to be patched because of a nail in the tread.

Googling around informs me that improper balancing, or over inflation can be one possible cause.

Take it back to the shop that made the repair.

Scary shit. I had a death wobble in my '57 CJ-5 last summer. It's crazy how much force is at the steering wheel with mechanical (non-power) steering.

The last time I had the wobble was on my 05 duramax, had 230k miles on it without ever changing a part. Got underneath it and everything on the front end was wore slap ass out.

Replaced all tie rods, pitman arm, idler arm, ball joints and the damn thIng is still off. no more wobble, but can't get the tires aligned right and it vibrates like hell.

This is why we can't have SFA.

I don't have a jeep and know nothing about them but I've had the front end shimmies before.

Ball Joints? tie rods? That was my issue in a toyota..

You can with leaf springs. Most death wobble ive seen is due to worn control arm bushings on coil sprung jeeps

Ex wife's jeep broke the lower track bar mount off the axle twice, that made for an interesting ride.

Track bar

Have someone get in the car and have them move the wheel left to right and watch all the linkage points.
The trackbar attachment points are usually the culprit.

The dampener shock on the front was a factory bandaid. It will only mask the issue for a while.

It can happen on leaf sprung front ends - my '79 CJ-7 has done it and a poster a few above you had it on a '57 CJ-5.  

I've also had it on a '96 Dodge 2500 4wd - new controls did not solve the problem, neither did new tires, TREs or any other part the dealer thru at it under warranty.  Increasing the caster solved the problem - I did it in my driveway after the dealer threw in the towel.
Link Posted: 4/20/2016 7:43:54 PM EDT
It can literally be anything.

I had it once a week after I bought a 97 TJ with 100k miles on it. Had driven it around town a bit and never had any issues. One day, driving at ~45mph and the hood is shaking like you describe and swore the front was kind of moving side to side but wasn't sure. I thought somehow the hood straps had come undone. Stopped to check..nothing. Pulled the straps and they were on tight. Couldn't figure it out.

2 days later I had the tires/wheels changed out to 35" tires and we found that there was a bulge on the far inside of one of the front tires. No idea if that caused it, but I've had the Jeep for 2 years now and have never had anything like it happen again.

If you just had a tire fixed, make sure they tightened the lug nuts good. this will cause wobble and a lot of other issues, like tires coming off.

Yeah this.

Front tire pressure way too low, very cold, too fast over a bump.

Handlebars just explode out of my hands as the front end makes violent oscillations stop to stop.

When it spit me off (maybe 60?), all I remember was whap! whap! whap! every time my helmet hit as I rolled.  

My first motorcycle crash. Good times.


Not to minimize your experience OP. I've been in a Wrangler at speed that shouldn't have been at speed. Very unstable. It was not fun.

More than likely, it's going to be the trackbar or the hole the lower end bolts to being worn too big.

Nope... left it just the way it came off the assembly line.

Meh it's not as bad as it seems, you can let go of your steering wheel in a dw and the jeep will continue down th road straight as an arrow until you slow down. My jeep gets it all the time but I haven't bothered to fix it yet since I drive it only a few miles a week anymore.

Ouch.  

The bad tankslapper I had was hauling ass tire broke the ground but when I topped the gear out the tire came back down and the violent slapper ensued with the front end wobble.  I remembered to let it go, and was lucky the front end settled out instead of crashing.

Had that happen in my 2006 F-250 CC.  Had the whole family in the truck with and we were doing about 65.
It was violent shaking.  I thought the tie rod broke off along with a lot of other things.  Took it to a shop and they said all the normal parts that are culprits are worn out.

Swapped everything out and added dual dampers.  Not a problem since, but I still cringe when I hit uneven/bumpy road on the highway.

Maybe it's just a bandaid,  but a new steering damper solved the problem on my '96 Cherokee.  Super easy and never recurred, the old one had turned to mush.

Tie Rods, Ball Joints.  A known problem on Chrysler front ends. The geometry is bad to start with and the OEM parts are "sealed" and not greasable. Have yours looked at.

The right tire would go up after hitting a bump and jerk the driver side in wash rinse repeat and just amplified.   T link solved that

I high school I had a 54 Dodge pickup manual steering with a bent wheel (about a half inch of wobble).  Hit a bump just right at 35 mph and it would just about rip the wheel from your hands.  I eventually found a replacement wheel for it that solved that problem.
Link Posted: 4/20/2016 9:12:59 PM EDT
Oh Man, I know what you're talking about.

My 89 Jeep Cherokee had the same issue.

Steering stabilizer - which needed grinding to get in; both front wheels balanced, all new front end suspension and a drive shaft check to be sure.
Done with it finally. I redid the whole front end and that was it. My left side tire would bounce like nobody's business till I did the front end work. The grinding and installing the stabilizer and suspension parts worked.

Cheers!
-JC

This. At 130 + mph. Talk about pucker factor.



New steering dampener and new front tire fixed it.

And not hitting that particular bump the same way, at Bridgehampton.

Traction bar.
Check both bolts frame side and axle side. Probably need changed out maybe even new Trac bar.

Check pitman arm bolts.
Link Posted: 4/20/2016 9:18:56 PM EDT
Track bar bushings and not enough caster are common causes.  And generally worn out suspension components.  And tires without stiff enough sidewalls.
