Can someone explain IN DETAIL and step by step how to adjust caster on an 01. 5 4x4? I've had it to the alignment shop twice and would like to avoid the $50/pop if possible. First trip was to set to 3. 2/3. 5 second trip was 4. 2/4. 5. Truck pulls left and would like to get a little more caster with less cross caster. Truck still has two indexing marks to go towards the front. Thanks BigSur
