Left front tire is balding on the inside closer to the engine... steering wheel shakes from 65mph+... im thinkn ball joints..but theres millions of things i think this is on a 04 f350 4 door 4x4..help please...and oh ya.. slight loss of coolant on long trips.. 3 hrs+

 

HI
how many miles on the truck

It could be the tie rod end worn (loose)

go under the front of the truck with the engine running in Park

get one of buddies to turn the steering wheel left and right

if it that bad you will see movement in the linkage before the tire actually moves....

Or you could have a bad tire??

I had the same vibration on my service van and it was a bad right tire...

at 60 miles an hour the vibtration went away

 

do you have a lift or leveling kit...i got bad bump steer and a crazy amount of inside wear on my tires about 6 months after i got my lift and i had to go in and add some more steering stabilizers and stuff
