Caster is the forward or backward tilt of the spindle. Forward tilt is negative caster and backward tilt is positive caster. Caster is not adjustable on the torsion bar or the strut suspensions. A slight caster adjustment can be made on the 1980-81 Type 2 Vanagon by moving the nuts on the end of the front suspension strut.
See Figure 3
Camber is the tilt of the top of the wheel, inward or outward, from true vertical. Outward tilt is positive, inward tilt is negative.
Torsion Bar Suspension
The upper ball joint on each side is mounted in an eccentric bushing. The bushing has a hex head and it may be rotated in either direction using a wrench.
The track control arm pivots on an eccentric bolt. Camber is adjusted by loosening the nut and rotating the bolt.
Spring on Lower Arm
Camber is adjusted by turning the upper control arm mounting bolt, which causes the two cams on the upper control arm to force the arm in or out.
See Figure 4
Toe-in is the adjustment made to make the front wheels point slightly into the front. Toe-in is adjusted on all types of front suspensions by adjusting the length of the tie-rod sleeves.
