When performing a PMI on the frame and suspension, a spring pin will not take grease with the vehicle weight removed from the suspension. The technician should next perform what step?

• A. Replace the pin
• B. Remove the pin to inspect and lubricate
• C. Apply more grease and reassemble
• D. Inspect the pin channel and clean

Answer: (B)

When grease won’t enter a spring pin with the suspension unloaded, the next step is to remove the pin to inspect and lubricate. Taking the pin out gives direct access to the bore and its channel, so you can look for debris, corrosion, or wear that’s blocking lubrication. Clean and lubricate the pin and its bore, then reinstall and recheck that grease flows properly. If the bore or pin is damaged after inspection, replacement is needed; otherwise, reassembly with proper lubrication should restore function.
