1997-2000 SUSPENSION
Front - Miata
DESCRIPTION
Front suspension is an independent, double wishbone design using upper and lower control arms. A spring over
shock is mounted between lower control arm and upper fender panel. Upper and lower control arms pivot at
crossmember and are connected by ball joints to steering knuckle. A stabilizer bar attaches to each lower control
arm and frame. See Fig. 1
. Upper coil over shock mount plate has been redesigned for 1999-2000. New design
incorporates a urethane bumper and improves ride and cornering.

ADJUSTMENTS
WHEEL ALIGNMENT SPECIFICATIONS & PROCEDURES
WHEEL BEARING ADJUSTMENT
Raise and support vehicle. Remove wheel assembly. Remove brake caliper and ABS wheel speed sensor.
Remove rotor. Attach dial indicator to axle hub, and measure bearing play. Check bearing axial play by rocking
hub assembly by hand. Maximum axial play should be .002" (.05 mm). If play exceeds specification, check and
adjust lock nut torque or replace hub and bearing assembly. See TORQUE SPECIFICATIONS
. NOTE: Mazda did not produce 1998 Miata models.
NOTE: See SPECIFICATIONS & PROCEDURES article in WHEEL ALIGNMENT.
