You can still find lot of DIY tools for toe adjustment.
I have 1 that looks like giant slide caliper with scale in degrees.
You measure the distance on the rear of tires, set it to 0 and then move to front.
The scale shows you aprox degree of toe.
I used it on my Mercedes where dealer butchered the alignment.
It is not easy as each stop can show 3-4 degree difference.
I learned to roll to flat spot and use parking brake for stopping to have consistent measurements.
Crooked steering wheels is matter of turning adjusting links on both sides in the same direction. Takes some try by error but doable.
