Front Suspension
Cadillac's front suspension not only cushions the ride but contributes to
stability and handling. Strut rods, mounted to the lower control arms and,
through thick rubber bushings, to the front frame crossmember hold the
wheels in firm fore and aft alignment during normal driving yet permit
a momentary rearward deflection of the wheel when it encounters a bump
or depression in the road surface thus cushioning the impact. Other
front suspension members, too, are mounted to the frame with rubber
bushings further insulating against road noise or shock. Rubber limit
bumpers cushion impact should bottoming ever occur.
Shock Absorbers
Cadillac shock absorbers are of an exclusive design with a gas-filled nylon
envelope replacing the air space in conventional shock absorbers. Since
there is no mixing of air with the fluid, efficiency is maintained even on
roughest roads.
Rear Suspension
Cadillac Four-Link rear suspension has two lower control arms to hold the
wheels in fore and aft alignment and two upper control arms angle-
mounted high on the rear axle housing, thus resisting both sideways motion
and roll on curves. Deflection of the rear of the car downward on quick
acceleration is also minimized. Thick rubber insulation at control arm-to-
frame mountings and at top and bottom of springs absorb and isolate
road noise.
