For 1990-2009 cars only
- Check and adjust the tire pressures to the pressures specifications shown on the tire placard, located on the driver's side door lock pillar.
- Note the load conditions under which the vehicle is normally driven.
- Ride in the vehicle with the owner in order to be sure you understand the complaint before proceeding to the next step.
- Test each strut dampener/shock in turn by quickly pushing down, then lifting up, the corner of the bumper nearest the strut dampener/shock being checked. Use the same amount of effort on each test and note the resistance on compression and rebound. Compare this with a similar vehicle having acceptable ride quality. Both strut dampeners/shocks should provide the same feeling of resistance.
