How to Measure Caster, Camber and Kingpin Inclination with DIY Turn Tables, Wheel Clamps, Gauges

***Update/Correction***: @7:03 you can read the King Pin Inclination. However, you need to level the gauge before reading the caster, just as was shown @6:30. Special thanks goes to @lizardking8388 for bringing this detail to my attention in the comments.

Wheel alignment should be checked anytime steering or suspension parts are replaced, if the vehicle hits a tooth-shaking bump or if the vehicle is involved in a collision. Professional alignments are over $100 due to $7-15K cost of highly sofisticated alignment equipment, shop time and the value of a professional technician. However, many DIYers have the skills to perform an alignment themselves. AutoSolo develops precision wheel alignment tools specifically for the DIY community. The wheel alignment turn plates, wheel clamp and gauges demonstrated in this video measure "Caster", "Camber" and "Kingpin Inclination" which are important for tire wear and handling.

Does vehicle need level

[@mrdiyguy123]

The vehicle in theory should be level. However, minor height differential from front to back impacts the results in a minimal way. However, I strongly recommend being level from side to side.

[@lizardking8388]

You made a mistake when measuring the castor. Before you measure castor, you're supposed to level the D gauge bubble a second time after turning in 20 degrees. The KPI gauge you measure directly before doing that.

Thank you thank you for providing constructive critism! I am better for knowing about this mistake and have have updated the description to describe the proper procedure. I want to share my knowledge and it needs to be correct! Thank you thank you!
I would like to send you a thank you present. Please add a comment to my video "XTOOL AD20 OBDII Scanner Review and Contest" to be entered in the draw and also check my channels "About" section and send me an email. Thanks.

looks to me that you have a lot to learn yet. first off you dont set your gauge to a level, you set it accordingly to the floor angle. use a digital angle finder on top of a 4ft level to get your floor angle and set accordingly. some vehicles require that the main frame be leveled out before caster and camber can be adjusted. front to back frame angle having an effect on caster and side to side having an effect on camber, this is referred to as z trim, and some require measurements from bump stop to cross-member or frame. keep studying you will eventually get there.

You are right I have lots to learn... and thank you for sharing above. Very interesting.

Thanks for the tip of calibrating to the floor level. It makes so much sense and is easier than trying to level my driveway.
