Step 5: Timing Left Rear Birdcage
Placing the square behind left rear birdcage, measure back 2 inches from top heim. Keeping square in the same place, spin bottom radius rod until it reaches 2 inches making left rear timing verticle (90 degrees). After completed, use marker to mark rods to keep proper alignment allowing you to make equal turns top and bottom when squaring the rear axle.
