Well awhile back I had problems with my truck vibrating. Well turned out it was a bent wheel. Well now my truck shakes but not all the time. It will shake, mostly feels like in the bed. It does it, but if I pull off the road. Put it in park, and cut it off, and then back on it stops. Think it maybe something electrical but am not sure. Any help is greatly appreciated.

 

im having the exact same problem man. i did some searching and i think i might have found an answer

Thanks. May have to try that.

 

Turned out my emergency brake cable wasnt releasing. Cheap 20 dollar fix from my mechanic.

 

Look for the flex hoses from the frame to the wheels collapsing in the inside; they do that. Happened to me.
Changed all the hoses and everything was fine again.
