Camber Issue.

That example is an AI Generated overview answer to a question. Many of those responses are completely incorrect or lack context at best, as this example does. The example they are demonstrating with is no way or shape a big truck, rather it represents an automobile design. The example can have camber adjustments made via shims or eccentrics depending on design.

 

Exactly. Expecting a wedge placed between an axle I-beam, which is rigid, and a spring pack, which is flexible, is just going flex the spring pack and not the axle beam.

 

The whole scenario of TA and alignment brings to question whether or not the measurements were even taken correctly. Was anything inspected for wear/ movement before angles were checked? And we need to know YMM and axle type.

Is everything assembled correct? Possible knuckles on the wrong side?

You need a second opinion.

 

You can adjust caster that way but not camber.

 

Looks like a good time for a 2nd opinion. All of his other posts are for a 9400. Never saw one of those with anything other than a solid I beam.

 

Correct, the wedges tilt the axle. Putting them sideways will just flex the springs so they sit crooked.

 

It's gonna be an issue with the kingpins. The shop that installed the axle probably didn't replace(or even possibly damaged) the bushings and bearing. The king pin connects the axle to the steering system and spindle. I've personally seen worn kingpins cause visible negative camber. Spring shims only partain to caster(the forward-backwards tilt of the axle)

 

The alignment should have been done when the axle was replaced. the numbers you posted are as if you have mismatched tires. Why are you getting an alignment done? uneven tire wear, drift? why was the axle replaced?
