Wobble on accelaration or deccelaration and severe on cruise
This is not a wheel wobble. It is the entire shifting of the vehicle. The particluar model does not have a dampner. Both front axles, shocks and struts, tires, CV boots, and rack and pinion have been replaced. The alignment has been checked.
It is a side to side type feel, much like a boat rock. It is predominent with hitting the gas and if it does start shaking then hitting the gas will stop the shifting.
Re: Wobble on accelaration or deccelaration and severe on...
I have had the same problem with my 96 Pathfinder for several years. When it got really bad I decided to look into it. The bushings on the rear stabalizer arms were worn out. The mechanic checked all bushings of the six stabalizer arms (two front and four rear) with a crow bar. The bushings of the two rear lower arms were bad as the arms were clearly loose. He tried to remove the bushings but could not as they were fused to the arms. So he had to cut the arms out with a torch and install new ones that came with the bushings. This completely solved the problem.

You need to check the front axle bearing. Once it gets bad it is the main reason for the shake or what is called the death wobble. Please get this checked before you have an accident. It is also contributed to bad tire wear and linkage damage. Hope this helps you out.
The noise at full lock is the pump screaming for mercy. All power steering pumps will complain a bit if the steering is held at full lock. Now, if the belt to the pump is loose, it will scream even louder, because holding the steering at full lock will cause the belt to slip. There is also a technical service bulletin for your vehicle concerning loud power steering noise which involves replacing the fluid lines and.or fluid cooler. This is not cause for concern, but an aggravation to the ears.
The "wobble" thing in the steering wheel is a whole different story. If it is wobbling all the time, it would almost have to be a tire/wheel or axle problem. I know you said this is not the problem, but I think you need to look again. Try rotating the tires to the back and see if the wobble changes. A very severerly warped brake rotor can cause this also, but will be much worse during braking. A bad axle shaft can also cause a wobble in the steering. This is consistent with your description of the problem changing during turns...A bad axle shaft can do this. Also check for looseness in the front wheel bearings.
I had the same problem; I had to replace the steering stabilizer and the track bar. There is a technician's service bulletin out about this problem; happens alot with Jeeps. Use aftermarket parts. It's called the "Death Wobble" and you can lose control of the vehicle very easily.
your bearings. thats what it sounds like to me. if it almost sounds like you have a big rock just jumbling around in your tire thats most likely your bearings. its pricey but its worth it to get it fixed. if thats not it check into your transfer case and your shocks
How are the tires wearing, could you need an alignment? Is the anti sway bar broken? When I hear that you have a clunking noise while accelerating I want to blame your CV joints, are you sure they are fine?
