Not true, the caster is adjustable to a degree, on
sub frame bolts by 3 mm in each direction, via slots
and captive nuts on the body points. This translates
into about 12 mm on the wheel side. Sometimes on
shunted cars with untrue sub frame points, the slots
are enlarged slightly, to be able to get the caster
adjustment right. After caster adjustment its
necessary to adjust for rear wheel parallelism.
