DIY Four Wheel Alignments

Was curious to know if any here do their own wheel alignments?

What techniques do you use?

Is caster/kpi, thrust angle, bump steer etc......... calculations ---------- included in your solutions?

I use the Hunter alignment rack where I work, but used to use string and a plumb bob in my driveway before that happened.

- Use a level surface
- Measure camber with a protractor against the wheel hub in comparison to a plumb line
- Measure caster with the steering wheel straight and a magnetic angle finder along the strut, or by measuring from ball joint to a known point along the longitudinal axis of the car (stamped hole in frame rail, etc)
- Measure toe with a broomstick or taut string placed along the level, center face of the tire. Measure from a given point on the body (doorseam, molding line, etc) to the string in multiple points and use some "SOHCAHTOA" to determing the angle

Finito!
