Stock TTB camber is -0.3° to +0.8°, caster +2.0° to +6.0°, total toe -0.19° to +0.31° (target slight toe-in). All three are adjusted through one part on each side: the upper ball joint alignment bushing.
The TTB front uses a single part to set both camber and caster on each side — the offset bushing that sits between the upper ball joint stud and the spindle. Rotate the bushing in its bore and you change where the ball joint sits relative to the spindle, which moves the spindle through camber and caster. That's the whole adjustment story. There is no inner or outer eccentric, no slotted bolt, no shim pack. The factory bushing (Moog K8975 and equivalents) comes pre-set at 0° offset, which works only if your suspension is at factory ride height.
Lift the truck more than about 1.5 inches and the beams rotate downward through their pivot arc, which pulls the top of each wheel inboard — negative camber. The stock 0° bushing has no way to correct it. The fix is an adjustable bushing — Ingalls 53200, Specialty Products 23910, or the Bronco Graveyard pair. These offer adjustment ranges from +0.75° to about +2.75° per wheel. Rotate the marked notch on the bushing to dial in camber, then accept whatever caster comes along for the ride. On taller lifts, you can also "cut and turn" the beam to add caster back — that's its own job covered separately.
Toe is set at the drag link / tie rod after camber and caster are locked. Loosen the adjuster sleeve clamps, rotate the sleeve to lengthen or shorten the tie rod, and re-clamp. Target is about 1/16 inch of toe-in measured at the front and rear of the tire at axle height. Use a long tape across both tires, or a pair of jack stands with a string pulled across, to take an honest measurement. The truck steers itself through small toe adjustments — a quarter turn of the sleeve moves toe noticeably.
Check toe on level ground with the truck rolled forward a car length to settle the steering. If the truck pulls and you've confirmed equal camber side to side, look at tire pressures and bearing preload before chasing more alignment changes. TTB trucks reward a careful baseline.
