Help! 95 Jeep Grand Cherokee Laredo-Violent Shaking.

Hi, I recently got a 95 Jeep Grand Cherokee Laredo. 4.0 V8 all stock. 197k miles. Calipers got stuck, replaced brakes, rotors and calipers. Supposedly has a rebuilt tranny 45k miles ago, this jeep was a mechanics lien( guy never paid for rebuilt tranny, mechanic kept jeep) But no paperwork.

I towed my 19ft inboard bayliner open bow about 45 minutes through windy hills. It definitely put some strain on the jeep. Since then as i accelerate its a bit more sluggish. but when i get to above 40mph, and only when i accelerate( lightly to heavily) it shakes extremely hard, steering wheel and whole front end just rattles like its going to fall apart. If i step on gas pedal to the metal it will accelerate fine no shake, and when i let go of gas gets perfectly smooth. I replaced cap and rotor/ air filter, fuel filter. All gauges read fine no warning lights come on and no overheating at all.

Suggested to me that u-joints could be going bad. However i drove with a couple doors inside truck and hatch was open so i could hear engine sounds out of muffler... the pitch would change alot and it was chugging and just sounded sick.

Ive read about the death wobble... but from what Ive heard that happens after hitting a certain speed and is a steady shaking. Mines only when i accelerate.

It seems like its not getting enough gas, but at the same time it doesnt seem to have any less acceleration.

I am stumped, but since I have three kids and this is my only vehicle, I'm hoping someone knows what this could be? I sincerely appreciate everyone's time!
Nick

First, you need to locate the shaking. Is it the engine or the steering? Is it a 4.0L inline 6 or a 5.2L v-8?

Well when its shaking the entire steering column shakes really hard. The whole vehicle jerks though. My wife could see it when it shook following behind me in her car. Thats what made me think its steering or u-joint or something... but the engine sounds and the chugging and half-sputtering is what made me question that.

And sorry yes its a 5.2 V8... not sure why i put 4.0

The gas issue could be a ton of issues from fuel to electronic. Does it rev up fine at idle and in the low gears or is the issue throughout every gear? Did you run it low on gas?

The death wobble could also be a ton of issues. Is there play in any of the steering linkages? Are the tires balanced correctly (can check doing a tire rotation to see if it gets any better or the shake moves to the rear)? Are the bushings in the control arms good? Are the hubs and ball joints good? To rule out a u-joint, grab the drive shaft and shake it to see if there is any play in it. I have yet to see a u-joint cause death wobble issues.

When i rev in idle it does shake a bit, engine is definitely running rough. And it does that really bad shaking i think in 3rd and fourth gear only when im accelerating(without stomping on pedal)
