Does anybody know what the alignment specifications are for a 99 F150 supercab with 4X4, short bed and 5.4? I don’t think the engine and bed size matter but I thew it in anyway.
Originally posted by Racerguy Alignment Specifications — F-150, 4x4
Caster R/ 4.6° ± 1.0° L/ 5.3° ± 1.0° Split/ -0.7° ± 0.7°
Camber R/ -0.1° ± 0.7° L/ -0.1° ± 0.7° Split/ 0° ± 0.7°
Toe (positive value is toe-in, negative value is toe-out)
R/ 0.10° ± 0.15° L/ 0.10° ± 0.15° Total/ 0.20° ± 0.25°
The left and right caster numbers aren’t the same? I haven’t sat down and looked at the geometry of the front end but it looks like my right torsion bar has to be cranked up a bit (right side of truck is about ½” lower than the left). With the right side a little lower will that cause the toe to be slightly out instead of zero to positive?
The caster is different from side to side to compensate for road crown. Without the caster split the road crown would cause a pull.
I dont think that 1/2" height difference will change the toe.
