Shake caused by wheels?

Why do you think the caster should be negative? It should be positive 8°

I actually wasn't sure if it was positive or negative 8. My bad.

I had the shake with my old tires and now with week old brand new tires. It gets worse as I drive, not better.  We put the truck up on a lift and put it in 4 wheel drive running through all the gears and rpms.  Right now the main culprit seems to be a bent wheel on the front right side.  It wobbles pretty good while on the lift.  I ordered some new wheels and I'm going to throw them on when they get here. Fingers crossed this fixes it!  It was really driving me nuts on the way to work today. Smooth right up to about 55 and then shakes pretty bad smoothing out again around 70, still shakes s little at that speed, but not as bad as the 55-65 range.  I tried throwing it it neutral while it is shaking and it didn't change a thing.

Is the steering wheel shaking or do you just feel the truck shaking in general? Have you done a dry park check of the front end yet?

[Chadwick717]

Just feel the truck shaking in general.  Have not done a dry park check yet.

Just wanted to update you all. Got two of the new wheels I ordered in and put them on the front. No more shaking! It was turns out that the old wheels were pretty bent.

Glad you got it figured out and fixed
