Here are pictures of a 2004 E450 28 Foot with Ingalls 594s set to MAX +CASTER:
Notes about INGALLs 594s:
Inner sleeve thinest is opposite the slot and is a fine tuner compared to outer sleeve.
Outer sleeve thickest is opposite the slot and is a coarse adjustment.
Passenger Side (M over S)Drivers Side (M over G)Note that the slot for the outer (coarse) is hidden under the apron of the inner sleeve BUT in both cases is to the REAR of the vehicle (The head of the pinch bolt is at the front of the vehicle in both cases. Also, in the pictures, the front wheels are cranked full front out for ease of access to top of upper ball joint).
