Front Suspension System: Diagnosis Mazda MX-5 NC рестайлинг

FRONT SHOCK ABSORBER INSPECTION

1. Remove the front shock absorber.
2. Inspect for damage and oil leakage.
3. Compress and extend the shock absorber piston rod at least three times at a steady speed. From the fourth compression stroke, verify that the operational force does not change and that there is no unusual noise. If there is any malfunction, replace the shock absorber.

FRONT UPPER ARM INSPECTION

1. Remove the front upper arm from the vehicle. (See «FRONT UPPER ARM REMOVAL/INSTALLATION»(ref-430328-S33579449072011101700000) ).
2. Inspect the front upper arm for bending or damage. If there is any malfunction, replace it.
3. Inspect the ball joint for excessive play, and if there is any malfunction, replace the front upper arm.
4. Rotate the ball joint 5 times.
5. Measure the ball-joint rotational torque using an Allen wrench and a torque wrench.

Front upper arm ball joint rotational torque 0.3-2.2 N.m {4-22 kgf.cm, 3-19 in.lbf}

1. If not within the specification, replace the front upper arm. (See «FRONT UPPER ARM REMOVAL/INSTALLATION»(ref-430328-S33579449072011101700000) ).

FRONT LOWER ARM INSPECTION

1. Remove the front lower arm from the vehicle. (See «FRONT LOWER ARM REMOVAL/INSTALLATION»(ref-430328-S18920388262011101700000) ).
2. Inspect the front lower arm for bending or damage. If there is any malfunction, replace it.
3. Inspect the ball joint for excessive play. If there is any malfunction, replace the front lower arm.
4. Rotate the ball joint 5 times.
5. Measure the ball-joint rotational torque using an Allen wrench and a torque wrench. Front lower arm ball joint rotational torque 0.4-2.9 N.m {5-29 kgf.cm, 4-25 in.lbf} If not within the specification, replace the front lower arm. (See «FRONT LOWER ARM REMOVAL/INSTALLATION»(ref-430328-S18920388262011101700000) ).

FRONT STABILIZER CONTROL LINK INSPECTION

1. Remove the stabilizer control link from the vehicle. (See «FRONT STABILIZER REMOVAL/INSTALLATION»(ref-430328-S24049272012011101700000) ).
2. Inspect the stabilizer control link for bending or damage. If there is any malfunction, replace it.
3. Rotate the ball joint stud 10 times , and then rock it side to side 10 times.
4. Measure the ball-joint rotational torque using an Allen wrench and a torque wrench. Stabilizer control link ball joint rotational torque 0.14-1.04 N.m {1.5-10.6 kgf.cm, 1.3-9.2 in.lbf} If not within the specification, replace the stabilizer control link. (See «FRONT STABILIZER REMOVAL/INSTALLATION»(ref-430328-S24049272012011101700000) ).
