Zero backlash

WARNING: This page is about a different car, the 2007 Ford Pickup and 2007 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
  1. If a zero backlash condition occurs, add a 0.50 mm (0.020 inch) shim to the RH side and subtract 0.50 mm (0.020 inch) from the LH side to allow backlash indication. Check backlash. Repeat Step 8.
