Ahh, as I go down the road at a comfortable 70 MPH all of a sudden the whole truck gets the shakes, it didnt used to do it. It isnt comming from the drivetrain, so hmm, suspension maybe?

Can you tell if the shaking is coming from the front, or the rear?

If from the front, you should be able to feel it in the steering wheel, the rear, you should be able to feel it in your butt.

Could be tires, suspension, or even the drive shaft.

Just give it some more heroin and the shakes will go away, lol

Sounds like somethign is out of ballance to me.

dewman

Me too, could be a tire that has equalized...

Ty

equalized?

jonny150

that happened to me...then i realized that i need to rotate my tires. That took care of that. It seems the i beam suspesnion dont like tires.

"The tech speculated that when I hit the pothole and bent the wheel, it was pushed into the tire, increasing the pressure. When pressure equalized, it went to the weakest part of the tire (still the sidewall, even on a run-flat), creating the bulge and ruining the tire."

From an Edmunds.com blog.

depending on how old the tires are you could have broke a belt

Tires are only 6 months old, It comes more from the rear than the front and I dont feel it in the steering wheel.

That would tend to suggest the issue is in the rear of the truck. You could take it to a tire shop and ask them to check the rear tires to see if they have come out of balance. Sometimes the little lead weights, they use to balance the tires, will come off which will "unbalance" the tire. If they are 6 months old, you may have a warranty on them.
