Long story short I hit a series of pot holes in a construction zone 2 lanes same direction of travel with closed shoulders and traffic to my left. I couldn’t miss them no matter what I did.
truck now pulls to the left. No play in any front end joint that moves. New wheel bearings prior to this incident set to 0.000” end play with dial gauge per nearly all major tapered wheel bearing mfg procedure. Wheels spin freely, calipers not dragging.
truck has been aligned and I dead center in spec. Still pulling to the right with steering wheel 10* left to keep straight.
I have also swapped the tires side for side on the front end with no change in the amount of pull. Checked tread depth and it is 12/32 all around both front tires in all grooves.
The steering wheel was perfectly centered while driving prior to this with no pull.

what am I missing?
many input is greatly appreciated!

 

Which wheels hit the holes? It pulled left and they changed the toe and now it pulls right?

 

Right side wheels, truck has pulled right since then with steering wheel needing 10* left turn to keep straight. No the pull did not change. Alignment had no effect.

I was hoping swapping tires across the front would make it change to a left hand pull but the pull remained to the right.

 

Maybe in the bushings on the 4 link arms? Check the right rear wheel bearings.

 

2 wheel drive has control arms, no 4 link.
hopefully it’s not the right rear bearing I just replaced the rear bearings back in January. Will check them out again though.
What gets me as of yet is that everything is within spec. Even the .22 thrust angle (which has not changed since it was last aligned in 10/2016)
something is off somewhere I just don’t know what or where
ETA.
just got done measuring lower ball joint stud to the same point on frame both sides cross corner squaring both sides are the same at 91-11/16”
straight line measurement to cab mounts on same side from ball joint lower stud is the same both sides to center of bolt front mount and then to rear mount. Axle tube to the same point measured for the front is the same distance as well.

ETA.
found 1 small spot that looks like impact damage on right rear. Measurements do not indicate that a belt has broken, measurements all around the tire indicate all wear is within 0.010”.
tires rotated across side will test drive this afternoon and report the findings.
right rear wheel bearing is good to go. Adjusted brakes out while I had the wheels and drums off both still operate and return freely as they should with no hang or bind on either side.

 

Wheels are pointed left when steering wheel is straight. Split the difference and mathematically center the wheels and the steering wheel is steering right.

this makes sense why it pulls right since the wheels are trying to get back to straight.
what doesn’t make sense to me is that I have to pull so far left. The only theory I have is that the control valve for power steering is allowing pressure since the wheel is turned right helping to push it further right and I’m having to overcome that pressure plus the natural pull of the wheels trying to go straight.

 

Yeah, if it's not centered it will try to return to center. Maybe damaged the link from the steering box to the axle or the steering box itself. That's why the alignment is still correct.

 

if you center the wheel and release it...does the wheel turn itself right or does the wheel stay in its position and the car drifts right

 

“There is a difference. Does the vehicle pull or drive straight with an off-center steering?

they adjusted nothing caster or camber wise...they corrected toe...but they left the steering off-center. toe does not cause a pull or correct a pull.”



Not to be smart about this but I have said more than once it [{(pulls right>, I have to steer left<. )}]



I have swapped tires side for side with no change in the amount of pull to the right.

If I let go of the steering wheel it moves right slightly as the vehicles veers further and further to the right.

 

Any possibility there are problems with broken/busted shocks? Deformed shock tower(s)? Damaged leaf springs or their bushings? Just thinking.


p.s. what is ETA in your posts?
