Front Suspension: Diagnosis Mazda MX-5 NB рестайлинг

FRONT SHOCK ABSORBER INSPECTION

Inspect the following and replace as necessary.

1. Inspect for damage and oil leakage.
2. Inspect the rubber bushing for deterioration and wear.
3. Compress and extend the shock piston at least 3 times. Verify that the operational force does not change and that there is no unusual noise. Compress the shock absorber piston and release it. Verify that the piston extends fully at a normal speed.

Scheme 4

1. Clamp a shock absorber flat or with the piston downwards.
2. Drill a 0.08-0.11" (2-3 mm) hole at a point 0.79-1.18" (20-30 mm) from the bottom of the tube, so that the gas can escape. WARNING: Whenever drilling into a shock absorber, wear protective eye wear. The gas in the shock absorber is pressurized, and could spray metal chips into the eyes and face when drilling.
3. Turn the hole downwards.
4. The oil can be collected by moving the piston rod several times up and down and cutting the tube at the end.
5. Dispose of the waste oil according to local waste disposal laws. NOTE: Shock absorber gas is nitrogen gas. NOTE: Shock absorber oil is mineral oil.

FRONT LOWER ARM INSPECTION

1. Shake the ball joint stud 5 times.
2. Connect the SST to the ball stud, and measure the rotation torque using a pull scale. Replace if it is not within the specification. Rotation torque 0.4-1.9 N.m (3.5-19.5 kgf.cm, 3.1-16.9 inch lbf). Pull scale reading 3.5-19.1 N.m (0.35-1.95 kgf, 0.78-4.29 lbf).

FRONT UPPER ARM INSPECTION

1. Shake the ball joint stud 5 times.
2. Connect the SST to the ball stud, and measure the rotation torque using a pull scale. Replace if it is not within the specification. (Scheme 5)
3. Rotation torque 0.3-2.2 N.m (2.8-23.4 kgf. cm, 2.5-20.3 in. lbf).
4. Pull scale reading 3.0-22.5 N (0.3-2.3 kgf, 0.7-5.0 lbf).

STABILIZER CONTROL LINK INSPECTION (FRONT/REAR)

1. Remove the stabilizer control link from the vehicle.
2. Inspect for bending and damage.
3. Measure the ball joint starting torque. Rock the ball joint stud side to side 10 times. Rotate the ball joint stud 10 times. Measure the starting torque using a suitable Allen socket and a torque wrench. Replace if it is not within the specification. Starting torque 0.2-2.7 N.m {1.4-27 kgf cm, 1.3-23.4 inch lbf).
