'99 Jeep Cherokee Sport is shaking on freeway

[hoggs222]

I have a '99 Jeep Cherokee Sport with a ton of miles on it. It shakes on the road when I go over 55 or so. Could it be as simple as unbalanced wheels or do you think it could be a stabilizer bar?

If it is a violent shaking of the steering wheel than you have a condition known as death wobble. Especially after hitting a bump at higher speeds.

If you just feel a vibration than its likely a tire issue, either out of balance or possibly a separated tire.

I would have to go with Death Wobble. What are some common causes for this?

Loose front end parts, or an alignment off.

Do you have stock tires?

Lift kit?

What do you have the tire pressure set at?

I will agree with loose front end parts. I will also add that I have seen the lateral link (bar from frame to axle, I may have called it by the wrong name) get sloppy at the frame on the drivers side. I have also seen the holes for the mount on the axle oblong.

If everything is tight than it wouldn't hurt to try a stabilizer shock.

It has stock tires, inflated to the correct psi, and no lift kit.

To check the loose parts would it be beneficial to leave it on the ground, not on a jack?

You will want to jack up each side under the axles. Use a pry bar to lift up under the tire to check the lower ball joints, not very common. Push in and pull out on the top of the tire to check the upper ball joints, again not that common. Push and pull at the three o'clock position on the tire to check tie rod ends.

I think the passenger side knuckle has two tie rod ends attached to it. One will tie the two knuckles together. The other is from the gear box. Make sure the one from the gear box is tight at the knuckle.

shake in the hands = front end shake in the butt = rear end shake all over? = really broken!....really. pulling left or rite? only at speed? if brakeing does it cut out? turning either way at 55 clear it up? have u tossed a weight? look for the print "where it was" if its just started....did u let someone use your ride? and my tip of the day...if it burns gas- breath's air-or is your girlfriend- dont loan them out and don't want them back! lol that should help u narrow it down......
