2001 jeepgrand cherokee wobbles and shakes @low speed

You have two unrelated problems. the power loss can be from a variety of things. What you first need to do with that is have a scan done (many parts stores do that free)...then if you have codes stored, you at least have some direction to go in with that.
The shaking is called death wobble and also has many causes. The most common are bad ball joints or tires that are worn sufficiently so as to not have enough foreward momentum to not react to side loading from bumps. The same tire can still generally pass inspection but is no longer useful on your vehicle (usually with around two thirty seconds of remaining tread measured at the wear bars). Any wear in any of the front end steering components or bushings can also cause wobble...sometimes it is a cumulative effect of slight wear in several places totaling an unacceptable amount of overall play. If you just had brake work or new tires installed, sometimes improper torquing of the wheels can also cause that. If you don't see anything obvious have an experienced jeep tech look at it. It can be dangerous and is nothing to ignore or wait on.

have the struts checked

try changing the tires . you may have a broken bead in a tire, which flattens when you hit higher speed.

Cheap fix is to get wheels balanced first then work from there to tie-rods, steering gear etc.

sounds to me like a bad inner cv axle joint my 2000 grand prix had one go bad and it would shake it almost out of my lane on acceleration but smooth as can be coasting same problem your having mine happend to be the passenger (longer of the two) side i think what you are feeling is the joint binding under accel hope this helps a fellow gp owner

Hi Tony,

There is a problem with either the the wheel integrity, the steering linkage or all the above.

This is a dangerous and potentially life threatening situation.

As someone who has lived through a ball joint breaking off of it's connecting rod, I can tell you first hand that a steering wheel that doesn't steer is no fun at highway speeds.

Please have your vehicle looked at by a pro.
If you drive it, drive it slow, but drive it to a mechanic.

Haha the death wobble replace the steering dampner or shock on the lower tortion bar of the suspension with an heavy duty upgraded one. Not a difficult repair check the tortion bar bushing for play. But the death wobble is caused by the steering shock. Seen it a lot fixes it every time. Hope the info helps rate it please.

The bumps do initiate the shaking. When my 2006 Ram 2500 4x4 started shaking, I had just had it aligned that morning. A month or so before that alignment, my passenger side outer tie-rod broke while driving down a rock road. I replaced it with a heavy duty MOOG tie-rod end. Anyway, the same day I had it aligned I was driving back home from a job and towing my bobcat behind me. I hit a bump and the truck did the "death wobble" with the front end shaking violently up and down in an alternating fashion (one tire in the air while one tire on the ground and then vice-versa). I changed the tires first (which were worn-out 305/75/17 mud tires). Since the day I bought the truck new in Jan. 2006, I've had larger tires on the truck than the tiny 235/75/17s that came with it and I've done a lot of heavy towing with it and never had a problem until this alignment was done at Sears. I;m still trying to figure out if it was the alignment specs that they used or if the problem coincidentally started that same day. I also changed the steering stabilizer. Neither the new tires nor the stabilizer/damper helped the problem. So I changed the other outer tie-rod end and the upper and lower ball joints (all MOOG with grease fittings). I turns out they were worn out. So, the truck no longer shakes violently up and down when I hit a bump. That problem seems to be in check. However, now when I hit a bump the truck's front end wobbles side-to-side. I can do a few things to recover from it. I can hit the brakes pretty hard and sudden (which can cause an accident on the interstate), or I can **** the steering wheel side-to-side a few times (from 10 o'clock to 2 o'clock) and that stops it immediately...until the next bump in the road. Also, if I let my foot off the accelerator just before hitting a bump and let the truck coast over it instead of power through it, sometimes the truck will ride over the bump without incident. I found out yesterday on a 5 1/2 hour road trip that if I did 80 to 90 miles per hour and powered through every road blemish, the truck rode fine...no shaking at all. I suppose the high speed forces the tires to stay straight when they hit a bump. Lastly, to confuse my problem solving attempts further, sometimes the truck rides like a cadillac (for an hour or so) at regular speeds and no matter what bumps I hit. Then without worning, the front end will loosen up and get that sloppy feeling again and the wobbling comes back at every bump...until the next time it feels like tightening up and driving right again. I have no idea what to do now. I'm going back to Sears today to have them check their alignment. Other than that, all I can think of is to change the rest of the steering components and check the steering box for malfunction. I hope someone can help all of us Dodge owners out off of the road tested info that I've just provided. Dodge doesn't seem to care to address the problems with their trucks front ends, and we need a solution before people get hurt or die. I was almost run over by an 18-wheeler trying to figure out how to handle the shake. I can't afford to buy another truck. So I need to fix this one so I can keep working. If anybody has a concrete solution to these problems, please let us know. I've read 20 different opinions from mechanics on these blogs, but nobody has said yet that they fixed someone's truck with these problems and have since heard from that customer and everything is still working fine. Opinions are helpful sometimes, but they're also confusing when they're conflicting.

most of the time, it's the trac bar bushing. if it's worn, you can death wobble over 40 mph. replace it with a polyurethane bushing.

this is known as death wobble because it feels like you are going to die but slowing down will end it.

The cause for death wobble are:

1. Worn or loose tie rod ends on your steering linkage.
2. Worn or loose trackbar bushings or tie rod ends on the trackbar itself.
3. front end needs alignment.
4. and many others but the common reasons are listed above.

try to realign the front end. If it doesnt help, then you do indeed have worn steering / suspension components.
