Front Suspension: Diagnosis Mazda MPV II рестайлинг

FRONT SHOCK ABSORBER INSPECTION

1. Remove the front shock absorber from the vehicle.
2. Inspect for damage and oil leakage.
3. Inspect the rubber bushing for deterioration and wear.
4. 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. If not as specified, replace the shock absorber. Compress the shock absorber piston and release it. Verify that the piston extends fully at a normal speed.

Scheme 2

1. Clamp a shock absorber flat or with the piston downwards.
2. Drill a 0.08-0.12" (2-3 mm) hole at a point 0.8-1.2" (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. Drain the oil 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.

Scheme 3

1. Remove in the order indicated in the table.
2. Install in the reverse order of removal.

FRONT LOWER ARM INSPECTION

1. Remove the lower arm from the vehicle.
2. Inspect for damage, cracks, and bending.
3. Inspect the ball joint rotation torque. Rotate the ball joint five times. Connect the SST to the ball stud, and measure the rotation torque using a pull scale. Replace the ball joint if not within the specification. Ball joint preload 9-43 inch lbs. (1.0-4.9 N.m). Pull scale reading 3-11 lbs. (10-49 N).

Scheme 4

Scheme 5

1. Remove the crossmember. See «FRONT CROSSMEMBER REMOVAL/INSTALLATION»(ref-169486-S00694164162004120900000) .
2. Remove in the order indicated in the table.
3. Install in the reverse order of removal.
4. Inspect the front wheel alignment and adjust it if necessary.

Scheme 6

1. Apply rubber grease to the inside surface of the stabilizer bushing.
2. Align the bushing with the inside of the positioning plate on the stabilizer bar.
3. Install the stabilizer bracket.

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).

Scheme 8

1. Remove in the order indicated in the table.
2. Install in the reverse order of removal.
