Truck shakes!

Probably needs alignment toe prob all jacked

 

Didja check your tire pressure?
I had a truck that did similar, and I when I checked and filled the tires the shake went away until the pressure came back down far enough.

 

Could be a tweaked out of balance drive line.....

 

when you push the clutch in at these speeds duz it still shake , or only under power???

 

get your steer tires balanced first if it hasn't been done recently. amazing what kind of shaking, think you got a bearing coming apart when one of em is out of whack.

 

inspect the tires too, I was in a volvo that shaked a lot and found on one of the steers it had a big bald spot, when replaced the shake went away.

 

Ninety percent of the time we see that it is the steer tires are cupped. Run your hand over the steer tires and see if they are smooth all the way around the tire. Alignment generally would not be off unless you hit something and then it would generally pull, wander or give you tire wear...but not generally vibrate.

 

did you inspect those steers first?
