Alignment Woes

In the print out it shows your rear axle is trying to push your truck to the right. Anytime the rear is negative on 1 side and positive on the other the truck will be pulling or pushing, I'm sure every one has seen the lifted truck driving down the road where it looks like it is touching the white and yellow line at the same time . Techs call it dog tracking, the rear end needs to be pushed forward on the right and back on the left until the rear toe is as close to .10 degrees on each side

 

Haven't touched it since this post and it's been great, so yes. Tracks straight, no bumpsteer, and tires are wearing even after 6k miles. I don't trust alignment techs after I saw them "bump" the numbers to make it "look right." Those lazy jerks.

 

I had the same issue with Firestone here in Fairfield. Completely messed up my alignment and the so called alignment "tech" didn't even re-center my steering wheel. Also got my oil changed there (same time as alignment) and they lost one of the bolts on my TRD skid plate door. Ended up going to Alignment Services in Walnut Creek. The tech there got everything corrected and let me know that Firestone did a pretty crappy job.

 

But in addition, your caster measurements are the reverse of where they should be. Lowering the caster on the right will only make it pull to the right even more. Remember that caster pull toward the lower number. Typically, once you get the thrust angle straightened out, you'll want .3-.5 degrees less caster on the left, not on the right.

 

The only thing that changed on your first alignment was the toe. You are pretty close to 0° toe. I know that is what most here will recommend, but in my experience it makes the steering very twitchy even with <3° camber. Add back a little bit of toe.

 

Agree. Some toe helps load the steering components to make everything feel "tight." That said, OP could have a worn steering or suspension bushing that makes the steering feel great with too much toe and bad with toe in spec.

 

I stopped reading after this.

 

Oh right, that was a typo. I meant less caster on the left. Thanks for catching that. Sorry @taco_boy didn't mean to hijack your thread, but since you're tracking straight now...maybe I can piggyback.

 

Can you guys recommend the best way to get my thrust angle evened out? I'm not sure my alignment Shop will adjust the rear.

 

Just ignore it. It doesn't matter. You are talking fractions of a degree. No one will notice it while you are driving down the road and it has no impact on anything.

 

I did it old skool. Flat ground, measuring tape, string and time. Those machines are no good if the tech isn't.

I just copied what this dude did. Started with caster/interference measurements (measured across and diagonally from reference point on ubolt to lca). Did it till even, measured forward and aft with center line on front tires (Wildpeak MT has it) while turning tie rods little by little and tires barely touching ground. Been driving at highway speeds and no issues whatsoever. Hope this helps.
