pulls to the right...still pulls to the right....still pulling to the right

[ripple]

I did solve a pulling problem on this truck last summer by rebuilding the FR caliper.
Got new tires and noticed a pull to the right. Maybe it was pulling some with the old tires, but I wasn't as
concerned then.
Replaced tie rod, front right caliper, adjusted bearing RF, swapped new tires around, plus what seems like every other thing that could make it do this.
Finally brought it to my buddy's shop and got it aligned with the fancy machine. Toe is set to within .001.
All is well, except for the pulling. And we are all stumped.
The pull is constant too the right, steers with less effort to the right, if I take my hands off the wheel
it goes toward the right immediately at really slow speed.
I'm gonna cruise around again and see if anything heats up differently, hubs or brakes, but I haven't noticed anything before.
Is it possible that my camber: 0.3 deg on the left and 0 deg in the right could cause this? Camber is still in opposite direction per the readout. They aren't both leaning to the left.
Not sure what to check next. Thanks in advance.

Is the road crowned

Sounds like you have an issue with your power steering box.

Lots of people forget this.

Here in WA the roads have a little ‘extra’ crown on state highways over the interstate & esp driving out to the coast or in our convergence zone it shows up in your tracking.

Have you checked your Right REAR brake?

Due to poor bleeding on my LSPV, my RR brake tends to drag.

 

[White Stripe]

Try driving on the left side of the road(when their is no traffic obviously) and see if it still does it.

 

[ElJayBird]

I have exactly the same issue. I've got a passenger rear caliper waiting to get installed.

Poor bleeding is not the cause of a dragging brake.

I would start checking control arm and panhard bushings to see if they're trash. Mine use to wander all over the road. Wheel bearings were loose as hell and the sumo or whatever Chinese tires on there were horrible and my front control arms and panhard bar bushings were meh so I changed tires and tightened the bearings and replaced the front bushings and it's a whole new vehicle now. I also took up alittle of the slop in my steering box and that helped some too. Mine was wondering all over though not just to the right but on new england crowned roads it did pull to the right. Exspiecally if there was a crack in the pavement on the right tire side which is common here...

When you're testing your pulling to the right are you doing it on the same road every time? Concrete is usually a better surface to test on since it usually isn't crowned and isn't as prone to the sinking and such that pavement see's.

This. Bring the truck to AUS, the pull to the right will be fixed instantly and the truck will pull to the left Aussie roads are crowned, sloping to the left, over here trucks pull left.

If you have play in anything as @Warpigg listed, it's going to follow the shape of the road. If it's doing it gently, you probably have some wear and tear in something in the front suspension or steering, or not enough toe in. If its not a gentle pull, maybe caster is inadequate

What happens if you let go of the steering and brake on a truly flat bit of road? does it still pull right on the flat?

It's not the crown in the road and that one is scary to test in the US. I did get an infrared thermometer to see if any discs were heating up after no braking and they are 90f and the hubs are 70f. No disc extra warmer than anything else.
On flat and sandy ground no hands, brake, and the truck goes to the right. Almost like it wants to steer itself.
My next task is the front left caliper. I suppose it's possible that the front left brake isn't dragging enough?

 

[LINUS]

Another thought is that they “idiot-proof” cars to slightly veer R so if say you fell asleep at the wheel, you don’t plow into oncoming traffic/cross the divider.

How bad are we talking - is this ‘slightly veers right a few inches every 75-100 feet’ or ‘OMG, Only a deathgrip keeps me in my lane!’ -type thing?

 

[dugsgms]

Do you happen to have the read out from when it was put on the alignment machine? Other than radial pull, improper cross caster is the major contributor to pull. Also, does the steering wheel rotate to the right when the vehicle is running but not moving or running with the front axle on jack stands?

 

[jeeprjames]

Have you checked your steering knuckles to make sure they are not loose underneath? 4 nuts per each side.

 

[baldilocks]

How much of the vehicle history do you know? Are you a newer owner or did this begin out if the blue after you owned it for years. Was it sudden or did the problem develop over many miles of use? Do you have crappy ass Korean made tires or do your tires read “made in USA” on the side? Do you have a lift? How much? What is your favorite color?

 

[slow95z]

And now I am running quotes in my head, why must you do this to me

 

[Jgunner]

Got an infared heat gun? Take a drive and shoot each brake caliper after. Shoot the hubs after that. If they are all within reason, then its something worn out or loose. Pretty easy to do.

Plausible, leakage in the control valve, would not be a common failure.

With the tires in the air, better yet the drag link disconnected from the pitman, what does it do?

My next task is the front left caliper. I suppose it's possible that the front left brake isn't dragging enough?

If the brake temps are even, it's highly unlikely.

Being in Aus, all vehicles here tend to pull left on a normal road that is raised slightly in the centre for water run-off.

Having a raised vehicle esp with altered suspension arms means there's a lot more 'natural' flex in the suspension and steering just because of the changed components. One thing I noticed with my 80 is that when it has more load it tracks better, but the steering still wanders a little regardless of everything else. Lifted 4wd's are a *lot* more fussy about toe-in being correct apparently.
