Truck is pulling to the right not sure what the problem is...

Check your U-joints on the steering shaft from the firewall to the gears. Just replaced the shaft itself (joints and shaft assembled) and I no longer have that same issue. It's kinda weird actually!

Cheers,

Are you sure you're not fighting wind? I've been having the same problem, then when the winds shifts, or I drive a different direction the problem goes away. I love it when the wind shifts just as I change direction. I end up fighting a headwind, or crosswind both directions.

 

Swap your steer tires and see if it pulls the other way....

 

rotate your steer tires from left to right and right to left. if the truck now pulls to the opposide side. it's a tire issue.

how bad is the pull??? if it's just a slight pull. that's normal. when roads are built. they are built with a crown. angled downward to the right so that water and snow run off. it's not uncommon for vehicles to pull to the right becuase of that. but it shouldn't be a extreme pull.

i've had cars. with bad tires. that when you took your hands off the steering wheel. the car would turn around a light pole. on it's own.

when mechanics do alignments most don'[t take that into consideration and just give it a standard alighment.

when i did alignments back in the day. i would adjust the left side to pull slightly to compensate for the road crown.

 

Jack the front wheel up and spin it. One of them is out of round or you have a broken tread. Granted with broken tread you will also get a thump-thump-thump-thump as you drive.
