Wheel Alignment Specifications & Procedures Mazda 626 GC

TIRE INFLATION (COLD)

Before attempting to check or adjust wheel alignment, ensure that tires are properly inflated. Refer to manufacturer's specifications given in owner's manual.

B2000 & B2200 Pickups

Change shims between upper control arm shaft and support bracket and turn upper control arm shaft until specifications are obtained.

GLC

Caster is not adjustable. If caster is not to specifications, inspect suspension for excessive wear or damage. Replace components as necessary.

RX7 & 626

1. Caster and camber angles are adjusted together by changing position of strut support. Remove 4 nuts attaching strut support to fender apron.
2. Raise front of vehicle and support with jack stands. Press strut downward and change position of support according to «STRUT SUPPORT»(/mazda/626/gc-1982-1987/remont/wheel-alignment/#wheel-alignment-specifications-procedures) and (Scheme 1).
3. Tighten strut support mounting nuts to 17-22 ft. lbs. 23-30 N.m). Lower vehicle and recheck caster and camber.

STRUT SUPPORT

Caster & Camber Adjustment Using Strut Support (RX7 & 626). Scheme 1

Adjust by adding or subtracting shims between upper arm shaft and support bracket until specifications for camber are within limits.

1. Raise and support front end with jack stands. Place vehicle in straight-ahead position.
2. Remove 2 mounting nuts holding strut support to fender apron. Push mounting block down, turn 180° and tighten mounting nuts. Note a triangular shaped mark on mounting block. Rotating mark away from engine changes camber to the negative side. Rotating mark in opposite direction, the opposite happens. Check camber angle.

Note. See procedure given under RX7 & 626 Caster adjustment.

626 (Front)

Loosen lock nuts and turn tie rods equal amounts. Both tie rods are right-threaded. To increase, turn right tie rod toward front of vehicle. To decrease, turn left tie rod toward rear of vehicle by the same amount. One full turn equals .24" (6 mm). If boot is twisted or dented, loosen band and straighten boot.

All Other Models (Front)

1. Raise front of vehicle. Turn wheels by hand and mark a line in center of each tire tread. Place vehicle in straight-ahead position and lower vehicle to ground.
2. Measure distance between marked lines at both front and rear of wheel. Make sure measurements are made equal distances from ground.
3. Loosen lock nuts and turn tie rods until adjustment is correct. Tighten lock nuts with bolts horizontal and below rod. This procedure will prevent interference with center link.

Scheme 2

1. Release emergency brake. Mark front and back of tire at same height as center of wheel. Mark center lower section of crossmember. Points marked on tires and crossmember form a triangle and are reference points for adjusting rear toe-in.
2. Turn spacer (star wheel) to make the points from rear of tire to center of crossmember equal. (Scheme 2) Turn both right and left spacers the same amount to adjust toe-in. (Scheme 2): Star Wheel Adjustment (626)
3. On GLC only, check parallelism of body and rear wheel. Use existing mark on rear of tire and hole on each side member. Measure from hole on one side to tire on the other. Repeat using other hole and tire. If measurements are not equal, loosen 2 crossmember mounting nuts on each side. Move crossmember so measurement is within.2" (5 mm).
