My way of checking my rc's alignments
1. Check all shock oils for proper level, air leaks etc.
2. Check spring load / tension, spring height's when not compress
3. Check shock spacer if fix or spring load tensioner spacer using caliper if adjustables.
4. Pick up and put down the rc vehicle on a table top gently. Avoid compressing all shocks, do not press down rc vehicle on flat surface. Let the rc vehicle seats on it's own weight.
5.. Check camber angle with the gauge if available or eye ball on top of the table for tire flatness or contact in the table surface. Adjust if need per your own settings.
6. Check Toe-In / Toe out.
