I searched on this and not seeing much.

Took my M1008 to a well known alignment shop and told them it needs alignment and its pulling the right. Also, its one of the few shops that can align tires that are 37" tall. Most won't. They work on many jeeps and other 4x4's along with suspension lifts, etc.

Anyway, get it back, still pulls to the right. Alignment spec sheet looks good. Bring it back to them and they try to swap the tires, inspect all the tie rod ends, king pin bushings, made sure all tires were same psi, etc. They said there is nothing else they can do to fix this.

Anyone else run into this issue of the Dana 60 pulling left or right?

I read some Dodge and Jeep guys are installing stabilizers that have 100 or 200psi to help offset this issue.

Truck has 5" lift, crossover steering, and new 2wd steering box with ORD brace.

No all tires rotate freely when it in the air.

Do you think the caster is doing this?

By that report you have no toe. Your total toe needs to show .10 ish.
Because you had bad toe before and bad toe now in the other direction I cant really pinpoint the pull lol

What that is saying is your tires are perfectly parallel. That is not correct even though its "in spec" and green.
 
Castor looks good. It should be a little higher on the right to compensate for the crown of the road. I don't see anything on that alignment sheet that would cause a pull.
If you jack up the front wheels and start the engine do the wheels start to turn(steer) on their own?
 
maybe a brake caliper is hanging up, and dragging the right side brake pads against the rotor...then again, naaaa.

I have always ran zero toe on all my solid axle trucks with no ill issues.

Are you sure its not road crown? Roads slope from the center out. One way to eliminate this is to find a road you know it pulls on, and drive on the opposite side of the road. Obviously dont do this in traffic or with other cars around. But a neighborhood with no traffic would be perfect. If the truck pulls to the left driving on the other side of the road then its the road. If it still pulls to the right then its the truck.

If its the truck look at everything on the right side. Brakes, wheel bearings, anything else like that. An IR thermometer makes checking for dragging breaks or bearings a snap. Dont rule out the rear axle pulling as well.
 
Friend of mine just went to the Hunter Alignment School. He is working at his father's shop, and turning into quite the mechanic. Another year or so, I may let him work on my equipment.......
Actually, he is doing really well.
I mentioned that for some reason my new car was slowly developing a slight pull to the right. I know all the tires have been road-force balanced, and the pull survived a tire rotation without changing.
The car is still in warranty, so I don't want a lot of stuff done to it yet unless the dealer does it, but I told him the next time his rack was not busy, lets put it on and see what is up.
I suggested a toe problem, or something like that, and he said that according to the school, only a camber problem would cause a pull to one side.
Of course, they are talking about alignment, not bad wheel bearings or brakes dragging.

I had to think about that for a while. It would seem that one tie rod out of alignment, but no, that would wind up as toe in or out, since you would tend to turn the wheel to even them out.

I'm still not convinced, but these folks are supposed to know what they are talking about, so until I hear something for certain different, I'm going with it.
Since my field is electronics, I did throw something at him, and he said that they mentioned that in the school.
My car has electric assist steering. And there is a computer involved. If I am on a long stretch of straight road, and don't move the wheel for a while, or let the lane assist do all the steering, it will shake the steering wheel and put up a message on the dash saying "steering required".
I said, what if the sensor that detects steering wheel position gets out of calibration? You might be holding the wheel straight, and the computer thinks you are commanding a slight turn.
Turns out they brought that up in the class, and had a test procedure for it........
 
Thanks for all the input on this. I will try the suggestions and see if that helps. I made sure its not the road crown by driving it in a flat parking lot and even at slow speed, it would pull a little.
 
If you make turn, and let go of the wheel, does the steering wheel return to center on it's own?
 
Have you tried swapping the tires side to side ?..
Sometimes a tire will cause a pull,and swapping sides will show its at fault by making it pull to the opposite side after its put on the other side..
My friend ran a tire/alignment and auto repair garage for 18 years ,he found a lot of vehicles didn't need alignment ,but instead needed new tires that way..after wasting time setting the vehicle up on the rack and finding it was within specs..

Also if the rear axle is not parallel ,it can cause a pull to one side and feel like its the front end causing it..
 
I've had a seized up front axle U-joint cause some scary steering and pulling issues before too...even in 2wd with the hubs unlocked..
