On-Vehicle Checks

WEAK
1. Check and adjust tire pressures. See label on deck lid.
2. Note load conditions under which the vehicle is normally operated.
3. If practical, ride with the owner to be sure you understand the complaint before proceeding to next step.
4. Test each strut by quickly pushing down (jouncing) and then lifting up on the corner of the bumper nearest the strut being checked. Use the same amount of effort on each test and note the resistance on compression and rebound. Compare with a similar vehicle having acceptable ride quality. Both struts should provide the same feeling of resistance.
^ Adjust alignment as necessary.

NOISY
1. Check all mounting for proper torque (bolt and/or nut). A loose mounting will cause noise.
2. If all-mountings are intact, jounce the vehicle to isolate the suspected unit. Test each strut cartridge by quickly pushing down (jouncing) and then lifting up on the corner of the bumper nearest the strut cartridge being checked.
3. If practical, ride with the owner to be sure you understand the complaint, before preceding to the next step.
4. Other objectionable noises may be detected by stroking. Any sound other than hissing is abnormal; replace the strut.
^ Adjust alignment as necessary.

LEAKS
1. Fully extend strut (wheels unsupported) to expose the seal cover area for inspection.
2. Look for signs of leaks in the seal cover area.
3. A slight trace of fluid is NOT cause for replacement; the seal permits some seepage to lubricate the piston rod. There is a built in fluid reserve to allow for seepage.
4. A leaking strut dampener/shock can easily be found because there will be fluid around the seal cover and an excessive amount of fluid on the strut. A leaking strut MUST be replaced.
