After alignment truck still pulls.

I have recently got my truck aligned and it still pulls to the left and I just wanted to see if anyone else has had this issue and any advice to fix the issue. Thanks!

 

Alignment looks good. Have you rotated your tires lately?

 

Did they only do 1 alignment, or do an initial and then destress the suspension and then perform a second? On Taco's my shop does 2 because of how sensitive these trucks are, and after destressing the suspension after the initial alignment everything changes. Doing the second gets everything where it actually wants to live.

It's also weird that it looks like all they touched are your tie rods and didn't touch your cam bolts at all. Lazy shop. Guessing they only did 1 alignment too given that that they didn't touch the cam bolts on the LCA's.

The before specs were pretty bad, how long did you drive the truck like that for? If more than a few hundred miles the tires could have uneven wear that's causing the pull.

 

Caster isn’t even, will pull left.

 

I got the tires rotated the same day as the alignment.

 

Just one. And yeah the shop was kinda crappy but I will try a different one and see what the outcome is. And I installed new upper controls arms that day and the truck might have been out of alignment for a few days not long.

 

Rotate the two fronts from side to side and see what happens. If nothing put them back and Rotate the rears side to side.

 

I’ve already tried that in the front but not the back. I will try that. Thanks!

 

yep, looking at the numbers the caster is too low on the left.

 

Op. Some have mentioned caster being lower on the one side. That is not your issue. Many of us run .5 caster higher on the right to compensate for road crown. That being said if your on a perfectly flat road you may have slight drift left but usually .5 degree is a non issue. Try the rears to make sure you don’t have a push. Keep us posted.

 

I don't think 0.4 difference in caster is that big of a deal. I'd try to get the rear thrust angle (axle) a little straighter and see if that helps. It is possible to adjust is slightly if your willing to do some leg work

 

Well I swapped the back tires and it still has a pull.

 

As an alignment tech I imagine the truck is drifting to the right? That would be because with your caster is about correct having a -0.4* split. But having a -0.2* split with camber is canceling out the road crown compensation. The vehicle will pull to the side with the least caster( left in your case) and the vehicle will also pull to the side with the most positive camber(right in your case) Camber pulls about twice as hard as caster so the 0.2* camber difference is canceling out the 0.4* caster difference. you'll have to get another alignment. A proper alignment should have equal camber side to side but around 0.5* most caster on the right side of the vehicle to compensate for road crown... also I wouldn't use more than 0.08" of toe because I find after that you start to wear the front tires abnormally

 

It pulls to the left.

 

Brake caliper dragging?

 

Steering wheel misalignment

 

A vehicle will pull to the side of least positive caster. So in your case your caster is lower in the left side hence your vehicle is pulling to left.

 

Which way does it pull in reverse?

 

Have you checked the air pressure in your tires?
