The steering system consists of a steering wheel,
steering column, steering linkage and standard or
power steering gear*
Standard steering with 24:1 gear ratio is basic
equipment on all models; however with certain op­
tional or accessory equipment the gear ratio will
vary from this.
Power steering, available as an option on all mod­
els, has ratios of 17.5:1 on Tempest, Firebird, and
Pontiac Catalina models; on all other Pontiac models
a new variable ratio of 16:1 on center and 12,2:1 at
full turn is used.
On power steering gears the repair procedures are
basically the same except for some adjustments. An
oil pump is provided to supply the power steering
system with pressurized oil.
