GENERAL INFORMATION

Periodic service of the suspension system consists of
regular lubrication as outlined in the GENERAL
LUBRICATION section.
Lubrication fittings are provided at the front suspen-
sion ball joints. Shock absorbers do not require
lubrication and, in case of leaks or malfunction, they
should be replaced.
Periodically it may be necessary to make certain
adjustments and checks of the suspension system to
maintain desirable handling and steering characteris-
tics and minimize tire wear. These checks are: front
wheel bearings, wheel and tire balance, lateral run-out,
upper and lower control arm spherical ball joints,
chassis springs, shock absorbers, and wheel alignment.
They are made with the parts on the car.
ADJUSTMENT PROCEDURES
FRONT WHEEL BEARINGS
NOTE: Tapered roller bearings have a slightly loose feel
when properly adjusted. This differs from ball bearings
which may be pre-loaded without adverse effect. Tapered
roller bearings can be damaged by the steady thrust on
roller en& which comes from pre-loading (Fig. 3-1 or
3-2).
