SERIOUS SHAKING WHEN DRIVING!

I'm pretty sure the shaking im getting is not from my front or carrier in the driveshaft.

Coming down a hill in gear last thursday my truck just started shavking violent but tracked straight for the most part. Dodged through traffic pulled off onto a side street and checked my front end over. Tie roads tight, etc. Drove home down the highway and no vibrations or shaking. Dropped the girlfriend off and then my truck just started to hiss sorta or make a sound like I flicked my exhaust brake on. Turned the truck off and looked around inside. Didn't notice anything to much, started truck back up. Hard brakes no steering. Turns out my belt tensioner broke loose. Got new one and new bolts as the damn bolt snapped off inside. Thought I was all good and drove the truck yesterday. No problems. This morning, no problems. This afternoon, started shaking like crazy. Pulled off to the side ( I was probably doing about 60km/h 4th) Popped the hood, tensioner is fine and so is belt. Obviously the shaking broke my belt tensioner then last week. Turned around to go home.. 3 times in roughly 35minutes it acted up and started shaking. I slow down lots or stop and it clears up. Usually around 50-65km/h this happens. Could it actually be death wobble? I don't see how that would snap my belt tensioner though.

Dual Mass Fly Wheel?
Front end issue?
Drive shaft?
Axles?
Balancing tires/ drive shaft?
Steady Bearing, Carrier?
Motor issue?

First, you gotta isolate whether it's the powertrain or the drivetrain. When it happens, shift to neutral and see if it persists.

Is it a 4x4 truck? Do you have the hubs locked (if they're manual hubs)?

Yup, it's a 4x4. Hubs are unlocked. Did it to me again yesterday.. just driving down the road and whole truck just started shaking like crazy for a few seconds. Maybe 2-3secs.

Shook again hard on me this afternoon. Driving down side street. 4th gear. Let it shake while I fought with the stick to get it into neutral. Kept shaking slowed the truck down. So now I think it's the motor more than front end or tranny or drive shaft.

Outside of the obvious bouncing around, does the engine seem to RUN ok when the truck starts shaking around? If putting it in neutral today didn't change things, I'd be most interested to know if there was any change if you let off the loud pedal or press harder? If it doesn't change with RPM, it isn't the engine.

It starts up fine... idles fine. I can drive it around town for ahwile then spontaneously.. it will just go into a siezure. I dont know how else to explain the shake. It just starts shaking like crazy for a few seconds and hard! Im giving it to a shop on monday ive decided. This is waaay outta capability to deal with.

If it kept shaking after shifting to neutral, then it probably is NOT the powertrain. If you can find the opportunity, drive it around until it happens, then put the clutch in and shut off the engine. Then engine movement is completely out of the picture. If the shaking persists, it's gotta be the drivetrain, or steering/suspension. Loose steering component, brake hanging up, driveshaft balance issue, could be about anything. You just gotta think through, then, what would manifest itself after driving a while....

Could be death wobble. Check your steering stabilizer. Happened to me on a 1997 f350 4x4 dually flatbed I've got.
