Strange front end vibrations ?
97 7.3 f350 CCLB. Around 40 mph & 65-70 mph my truck vibrates. Acts like tires are out of balance. I don't know what it is. But If I set something on the dash when it happens it rocks (like sunglasses ) or something.
What I've already tried.
-re balancing tires (brand new toyo mt 385/75-16s with 2000 miles on them )
My 35 toyo MTS never did this. Or I didn't notice that it did.
-new carrier bearing
-shimmed carrier bearing 3/4" (helped quite a bit with vibration from take off and turning Corners from a stop. (Didn't help going down the highway. )
I'm not sure what else to do. My wheel bearings have both been replaced within the last 3000 miles also.
Any ideas ?

I'm running them at 40 psi. I should try 35. Also I had heavy duty u joints installed 2 k miles ago. And since then when cornering I get a sound familiar to the sound of a bad wheel bearing. Is it just the new u joints ? Could be tire road noise. But like you said i try a different pressure
