DIY Alignment
This is awesome. Can you explain how to set caster? I have been reading but can't seem to figure it out.
Caster is not measured directly. You measure caster by actually measuring camber with the wheels turned in, then out, then subtracting the readings. Depending on how far (in degrees) you turned the wheels you multiply that difference by a factor, and the result is caster.
Caster gauges do the same thing. My old Ammco gauge is actually a sort of circular slide rule in caster mode. This assumes you are using a simple "tilt" gauge. Different alignment caster/ camber gauges use somewhat different procedures
Here
compute caster from camber - Google Search
"To calculate caster angle.
Turn wheel 20 deg ea way, multiply difference by 1.5
Turn wheel 15 deg, ea way, multiply by 2
Turn wheel 10 deg ea way, multiply by 3
If turn in reading is larger neg, the caster is positive."
