DESCRIPTION
Vehicles are equipped with front wheel drive and independent
MacPherson strut front suspension. Suspension consists of vertically
mounted strut assemblies, control arms and stabilizer bar.
Struts are mounted between inner fender and steering knuckle.

Ball joint connects steering knuckle to lower control arm which
attaches to frame crossmember. On Celica, stabilizer bar attaches to
lower control arms and 2 points on crossmember.
ADJUSTMENTS & INSPECTION
WHEEL ALIGNMENT SPECIFICATIONS & PROCEDURES
NOTE: See WHEEL ALIGNMENT SPECIFICATIONS & PROCEDURES article in
the WHEEL ALIGNMENT section.
WHEEL BEARING
Wheel bearings are not adjustable. Whenever bearings are
removed, replace with NEW bearings, races and oil seals.
BALL JOINT CHECKING
1) Raise vehicle, and place a wooden block with a height of
7.09-7.87" (180.0-200.0 mm) under either front tire. Lower floor jack
until about half vehicle load is on front struts. Place safety stands
under vehicle.
2) Place front wheels in straight-ahead position, and block
them. Use a rod to move control arm up and down. Check for vertical
ball joint play. If ball joint is damaged or any vertical play is
found, replace ball joint. See LOWER CONTROL ARM & BALL JOINT under
REMOVAL & INSTALLATION.
