FRONT WHEEL SUSPENSION
The 1957Chryslerand Imperial Carsare
equipped with a completely newrubbermounted
ball joint typeindependentsuspensionsystem
using torsion bars insteadof coil spring.(Figs.
1, 2,and3). Torsion bars makemore efficient
useofmetal, increases thefatigue life ofthe
metal andpermitaccuratere-adjustmentof

suspension which might occurafter long pe-
riods ofservice.Thisnewsuspensiongivesim-
proved steeringand directional stability and
with theanti-brakedip principle built into the
design, thetendencyofthe nose ofthecarto
dip whenbrakingisreducedtoa minimum.
Torsion barspringsalsopermitrelocatingof

points, sothattheirsteeringgeometriesare
morenearlymatchedresultingin less wheel

Front suspension heightshouldbecheckedand
if necessary, reset wheneverservice work has
been done onthetorsion bars. Thevehicle
shouldbeplacedona level floor with weightof
vehicle onthetorsion bars. (No passenger load,
full gastank).Usinga steelrule, measure from
thelowestpointofthe ball joint to floor, as
showninFigure13. Again usingsteelrule,
measure from theundersideoflowercontrol

higherthanthe ball joint housing.The differ-
ence between these twopointsshouldbeheldto

measurements ontheoppositesideofcarin
same manner. After thedifferential measure-
ments have been establishedfor each side,they
shouldbecompared.Theresultsmustbe held
