Car rides rough, feel every bump hear a squeaking noise when you push back of car up and down, smells like something burning, need clockspring

SOURCE: running rough

Several things to check but first is pull each plug and check for fouling. There are about 5 sensors totaling 150.00 or more that can cause this but it turns out I had a bad injector where the plug was fouling. Throttle Position Sensor(TPS), Mass Air Pressure sensor(MAP), and Coolant Temp sensor(CTS) will make the computer think it needs more or less fuel. Also I have discover that this engine has a bad reputation for blowing the intake manifold gasket due to improper torque from factory. Dont know if this is related but this forum has helped me alot.

Lifters, or maybe fuel injectors, clogged fuel filter, here are just a few it COULD be, as for the burning smell, belt, bad piston rings.

SOURCE: Rear shock replacements on '03 G. Cherokee results in "firm" ride. If shocks needs to be replaced, please advise.

Its likely that you got so used to the soft ride you had with old worn shocks that the new ones feel strange. You could buy a more inexpensive shock to restore that "old" feeling, but I don't think you really want that. One thing you should do though is to make sure by having a couple of people bounce the rear, that the shocks are not binding or are too long and bottoming out part way through the suspension travel. There is a part # stamped into the bottom of the shock just above the weld ...double check that part number to make sure you have the correct ones. Also check the standing height of the back end (compare the height of yours with others you find in parking lots...I have a 93, which measures 171/2" from center of rear wheel hub to edge of wheel flair.)
If standing height is too low, shocks are not working at the center of travel but at the lower part. (likely you would have noticed this more with the old shocks though). Additionally, there are adjustable shocks available that you can "tune" to your comfort level...they usually have three settings ...you choose the one that suits you best.
Hope something I said will give you a cure or an understandable reason for what you are feeling.
Don't forget though that a Jeep is essentially a small truck, as such, it's going to ride like one!

SOURCE: 2000 isuzu rodeo, it was riding very rough So i

correct size tires? correct pressure? aftermarket shocks ususally ride rougher than OEM. all bushings OK?

I would think, most likely the shocks are bad. The springs could be weak, but I would think it would sit a bit low. I'd check the stabilizer links. The vibration could be a bad universal joint in the driveshaft. I'd replace the shocks first.
