There are no methods available to adjust caster or camber. The only adjustable component are the tie rod ends for toe in.
The rear trailing axle also has no available adjustment.

So, the only way camber could be adjusted is to hog out the mounting holes where the strut attaches to the spindle and the only way caster could be adjusted is to hog out the upper strut mount holes.

All that to say you only need to verify and adjust toe in after a strut change.

See manual listed above......page 10-62.....wheel alignment and tire balance.

Moog makes parts, GM makes cars....who do you think should know best how/when service is called for?
A parts company or a auto manufacturer.

A car manufacturer has little to gain by telling a owner not to perform services unless the vehicle displays a need.

Here's my factory aligned car after 2,000 miles. Notice the alignment says FAILED. This was tested by the dealer when they warranteed the battery in December.

This is the car sitting still on the machine. Now imagine driving down the highway. With your alignment flexing outward at 70 mph. How much further it would be out.

Thank you for that informative post. @Eddy Cruze. I didn't think about the sensor

You drove over one of those toe in/tire depth measuring machines. Developed about two blocks from my shop, they are talking dealerships into installing them (buying them) on the write up isle so incoming service customers must drive over it.

They say the machine turns alignments into a easy sell with a 80% take rate.
Trouble is, every car has a different toe spec and the machine has no way to determine type or brand so it is set up with a average acceptable toe range.
Not very scientific but highly effective at selling unneeded service and adding to the bottom line.
