Zero the gage.
Roll the car forward until the chains just touch the surface rearward of the axle.
Carefully read the gage.
Repeat this, but be sure to roll the car back and forth like when you started. You have to normalize the suspension and steering system before you measure again.
Good luck

When the rear reading is taken, it should be 1/16" more than the front reading.
