Setting toe-in and camber within these tolerances while the cabin and fuel tanks are empty will give
approximately zero toe-in and zero camber at gross weight. Therefore,
if
normal operation is at
less than gross weight and abnormal tire wear occurs, realign the wheels to attain the ideal setting
for the load conditions. Refer to sheet 2 of this figure for shims availability and their usage. Al-
ways use the least number of shims possible to obtain the desired result.
