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

You also get that thump thump thump in Arkansas....

Right front brake dragging a little?

 

I think it will have something to do with the brakes, maybe right is adjusted tighter than left? If not that, Id check the brakes pads/shoes on the right. Might even check for cracked drum, caliper or rotor. Could also be wheel bearing going out.

 

I agree with another poster that it could be something as simple as road design. Also, from what I've learned about alignments, it's "standard" for it to be a degree off. Should you fall asleep or stop actively steering then the vehicle will roll into the ditch versus into the back of another vehicle. Every truck I've been in has this drift. However, if it's too much (meaning it happens too quickly or that you feel that you're overly compensating for it) then there are other factors to consider such as wind or mechanical issues.

 

Have you find the problem yet?

 

I know this is 8 years late but I have a chunk missing on the inside tread of the front stear tire and am having a pulling to the left issue and a little womp womp womp sound. You think this is the issue for the pulling. Definitely for the womp sound
