1 | Inspect each strut or shock absorber. Look for any indication of fluid leaking from the strut or shock absorber. Is the outside surface of the strut or shock absorber free of any indication of fluid leaking from the strut or shock absorber? | Go to Step 2 | Go to Strut Assembly Replacement in Front Suspension or Strut Assembly Replacement in Rear Suspension.
2 | Measure the tire inflation pressure. Refer to Tire Inflation Pressure Specifications in Maintenance and Lubrication. Is the tire inflation pressure correct? | Go to Step 4 | Go to Step 3
3 | Adjust the tire inflation pressure. Is the tire inflation pressure correct? | Go to Step 4 | --
4 | Road test the vehicle to verify the customer's concern. Did you observe the customer's concern? | Go to Step 5 | Go to Step 8
5 | Test each strut or shock absorber by pushing down and lifting up each corner of the vehicle. Use the same amount of effort for each corner of the vehicle. Does each corner of the vehicle stop bouncing in the same amount of time as the other corners of the vehicle? | Go to Step 6 | Go to Strut Assembly Replacement in Front Suspension or Strut Assembly Replacement in Rear Suspension.
6 | While pushing down and lifting up each corner of the vehicle, observe the resistance on the compression stroke and the resistance on the rebound stroke of the strut or shock absorber. Is the resistance on the rebound stroke greater than the resistance on the compression stroke of the strut or shock absorber? | Go to Step 7 | Go to Strut Assembly Replacement in Front Suspension or Strut Assembly Replacement in Rear Suspension.
7 | Test the strut or shock absorber on a similar model with properly functioning struts or shock absorbers. Ensure the suspension RPO code on the similar model is the same as on the customer's vehicle. Test each strut or shock absorber by pushing down and lifting up each corner of the vehicle. Use the same amount of effort for each corner of the vehicle.

Is the resistance of each strut or shock absorber on the similar model the same as the resistance of each strut or shock absorber on the customer's vehicle?

Go to Step 8

Go to Strut Assembly Replacement in Front Suspension or Strut Assembly Replacement in Rear Suspension.
