Next, check the fore-aft alignment between the control arm bolt holes in the Panhard-bar axle mount and the holes in the axle's lower-control-arm mount. Due to Ford's wide production tolerances, it may be necessary to elongate the Panhard-bar axle mount fore/aft with a file to allow the pivot bolt to pass through. This requires removing the mount and filing, as shown here. Don't enlarge the hole in the rear lower-control-arm axle bracket. Instead, remove just enough material from the axle mount so the 12mm bolt passes through the holes with a snug fit. Be careful not to excessively enlarge the holes in the axle mount. Afterward, reinstall it and retorque the bolt to 120 lb-ft.
