   If wheel angle deviates from the specifications, readjust the toe-in and wheel angle within the specifications. At this time, the lengths of the tie rod end may be within less than 1.5 mm (0.059 in.).

1. Find the wheel alignment standard value applicable for the tire size.

2. Mark the selected standard value on the adjustment chart in Fig 14.

   Example 2WD: 

   1. Camber -0°15' (-0.25°) 
   2. Caster 3°05' (3.08°) 

3. Mark on the adjustment chart in Fig 14 the alignment values measured at the vehicle height.

   Example: 

   1. Camber 0°00' (0°) 
   2. Caster 2°15' (2.25°) 

4. As shown in the illustration in Fig 14, read the distance from the standard value to the measured value, and adjust the front and/or rear adjusting cams accordingly.
   1. Example: 
   2. Front cam -(shorter) 1.5 
   3. Rear cam +(longer) 3.9
