Gracie, I read your other thread. The hydraulic system in no way will cause DEATH WOBBLE. It is just for power steering.
Death Wobble usually happens when you lift a Grand but it can happen to a stock Grand.
I asume your Grand is stock. When conrtol arm bushings, track bar bushings, shocks, and the sterring stabilizer get as many miles as your Grand has. They can be worn very badly. Not all of them usually but they can be. The rubber bushings in the control arms are hidden & can't be seen untill they are taken out.
This is where I would start. Have the steering stabilizer replaced. That is about the first thing that will cause beath wobble. It might look OK, but you can't tell just by looking at it. You said that you have allot of bumpy roads that you drive all the time. That would be one of the first things to wear out.
If that does not solve the problem I would have the track-bar bushings checked. Or a least make sure it is TIGHT on both ends. With stock track-bars I don't think the bushings can be replaced. The whole track-bar needs replacing unfortunately. I could be wrong about that though.
Shocks should at least be replaced at about 60,000 miles.
I would save the control arms for last. At least make sure they are torked to spec. ALL 4 of them.
One other thing that can cause death wobble is a front tire. When was the last time the tires were rotated & balanced? An out of balance tire can cause death wobble. Not that often, but it can. I've heard of a BAD tire causing it. That is, a tire with a broken or worped cord in the tire. Or it could just be out of round.
