Jeep Cherokee Grand Cherokee Steering Stability and Suspension
This is the 2nd Cherokee w/4 wd that I have had this problem with. At anytime on a highway the front end will go into a violent shake that sends me to the shoulder to slow down. Once I slow to about 30 mph it goes back to normal. It happened on my 1999 Chrokee 4 wheel and now on my 1997 Limited. If anyone has had this experience please help. Scarey to drive.

If they aren't lifted and/or "death wobble" is not your problem, then I'd look at the steering/suspension. First off, check your tierod ends. If they are worn/loose, replace them. Make sure the drag link ends are not loose as well. Check for worn hubs and ball joints. Basically, jack up the front end and check for any movement in the front tires. To check for a worn hub or bad balls joins, grab the top and bottom of the tire and try to rock it up and down. If there is ANY movement at all, then the hub and/or ball joints need to be replaced. Next grab the left and rigt side of the tire and try to manually turn it. When you do this it is normal for there to be a little movement side to side. Just make sure the other front tire and steering wheel are moving with the tire you are turning. If the tire seems to move rather freely for just a little without the other tire or steering wheel moving with it, then you've got a bad tie-rod end/ends or drag link joint.
You can grab the tie-rod itself and try to rotate it. It will rotate a small amount, less than 1/8 turn. If it seems to rotate freely, then the joints are bad. The same holds true for the drag link.
Finally, check that track bar. Make sure it is absolutely tight. I do know of one situation on a late model lifted Cherokee where it came loose. The guy was driving down the road and did the "death wobble" shake. Once he got it straightened out, he hung his head out the window and got it up to speed again. This time he saw the front axle literally moving from side to side. When he got home, the track bar was ready to fall out. He recentered the axle and tightened the track bar down, with some LockTite this time, and he hasn't had any problems since.
Good luck. I hope I helped.

Let me know what else. Thanks for the help. This is a bad wobble.
Caster is what makes the front end stable at high speeds and what makes the front end track straight when no other forces are acting upon it. If the axle were to be rotated forward, then the caster has been reduced or eliminated. This will cause the front end to lose their natural tendancy to "find" neutral and could cause them to wander rather violently.
Imagine a vertical line drawn through the center of the axle. Next, imagine a line drawn through the center of the steering knuckle. The steering knuckle line will hit the ground in front of the point where the vertical line hits. The difference in these two lines can be measured in degrees of the angle or in inches between the two points and is referred to as caster. The greater the angle, or greater distance, the more stable it will be at high speeds.
The tire, of course, will contact the ground where the vertical axle line hits the ground. It is the steering knuckle line that will "lead" the front tire. This is how you can pull a car around and the front tires will turn as the tow vehicle turns.
The most obvious examples of this principle are two motorcycles. The first bike being a racing bike, while the second is a cruiser - such as a Harley. The racing bike's fork is nearly vertical while the Harley's fork is stuck way out in front. The racing bike is very agile and the Harley is rather heavy by comparison. However, the racing bike is not very stable at high speeds and requires the total attention of the rider while the Harley is very comfortable and stable at high speeds.
I hope this helps. :confuse:
The replacement of the track bar cost me about $375 including labor. If your mechanic wants to do other things that cost more tell him your friend has had the same problem with 2 different Jeeps and both times it was the track bar. Don't let them just start fixing stuff. Long story but I am becoming an expert with this problem. Good luck.

I think that will solve your problem. If it doesn't, a SYE might need to be installed but I really doubt it as a 1.5" lift *shouldn't* alter the driveline geometry much for that. But again, each Jeep acts differently to a lift kit.
Also, I'd get a wheel alignment as the toe will be off a bit.
None of these repairs fixed the problem...my 2001 Cherokee Sport continues to vbrate/ wobble at between 50 to 58 mph.
My Jeep is NOT lifted and I have not altered the original suspension in any way.
Thanks
Thanks!
Thanks!
I lost my Monte Carlo that day but we all lived. Thank God!
The boy had no insurance and no DL.
My insurance refused to pay because it had just lapsed.
Anyway I am now in a wheelchair. My wife took my 95 Dodge Ram that had a bench seat in it and traded it for a 97 Jeep Grand Cherokee TSI, plus she gave the guy $800.00 to boot.
She did this so we all would have a car we can all fit in and put the wheel chair in.
Since I got out og the hospital I have driven it and noticed that it makes a grindind noice when I try to put it in 4 wheel drive or all wheel drive. It will work if I put it in low, but not the others. What is wrong with it?
The cruise control will not work either, and the fuses has been checked. ( I need that because I can't put presure on my leg)
I also noticed by being in the wheel chair that the driver side front tire is turned out further then the other.
I have everyone suing me for hospital bills, ect. While this 21 yr old is out on promation for 2 years.
So I don't have money to repair it. Cand someone please help me, please?
I suggest reposting your message in the Jeep Grand Cherokee: Problems & Solutions discussion since your questions are not specifically about steering problems. As an aside, we'll be restructuring the Problems & Solutions boards down the road a bit but, for now, it's the best place for you to start.
Good luck!!

Has anyone else had their tie rod ends looked at? How much is it to replace them?
Thanks,
Eric
Good Luck,
Eric
Perhaps one of the network news channels needs to be informed, also.
I suspect you put an extra 0 in there!

I'm going to get as much information as possible before I get into a chain of unnecessary expenses, since repairs and especially parts are expensive here in Hawaii. After reading all the reports, it looks like the first thing might be to rotate the tires (because it's free) and then look at the track bar. Any discoveries out there??? I can sure use the help.

I have had this problem with 2 different Jeeps 10 years apart. I am sure the balancing of tires will not help. Do not spend any money except get a new TRAC BAR put in. It will be a minimal cost of about $175-$200. Do not let your mechanic talk you into costly repairs. This will fix the problem. If for some reason it does not then move on to other expensive fixes. Tell them to replace the Trac bar and that should fix it. Please email me and let me know how it works out.
Been Jeep`en and off roading for years, and have had a similar problem myself.
With an old 1996 JGC that I run off road and on road here in Arizona.
We also pull our Quads with it.
Brake Pads can ware uneven and cause a brake caliper hang up. Or it can happen for other ware related reasons. This will give the ABS a big fit. It will cause one hell of a
shimmy in the front end and could happen in the back also.
In short, pull the fuse out of the ABS to disable it. Then drive it for a wile and see if that cures your problem.
No worry, the brakes will still work just like in the old days, but if you slam them on hard the wheels will lock up and slide, just like they used to before ABS.
If this cures the problem, have the brakes repaired or do it yourself if your up to it.
Best of luck with your problem.
