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.

Some would align with gas in the tank or a driver in the seat, For you a Burger on the hood. Great Video

Prio1 is toe, prio2 is camber, and u dont need prio3..and u can do the fist one with a cheap string..

Just ordered your stuff from Amazon. Would there be another name on specifications for the kingpin measurement? Also nice video.

How accurate do you think this method is ?

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.

My caster was set to 4.0 degrees two weeks ago. This tool says it's at 2.0 degrees. Doesn't make sense.

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.
