Which is NOT part of the proper chassis lubrication procedure?

• A. Apply lubricant directly to the surrounding frame
• B. Wipe the fitting clean with rag and press lubrication gun end to the fitting
• C. Operate the handle until you feel resistance
• D. Be familiar with all lubrication sites

Answer: (A)

Proper chassis lubrication focuses on delivering grease through designated fittings to moving parts, while keeping those points clean and ensuring the grease actually enters the joints. The steps involve wiping the fittings clean and pressing the lubrication gun end to the fitting so grease can enter, and pumping until you feel resistance to confirm the cavity is filled. Being familiar with all lubrication sites helps ensure every required point gets grease. Applying lubricant directly to the surrounding frame is not part of the proper procedure because lubrication should go into the fittings, not onto the frame; coating the frame can attract dirt and debris and won’t adequately lubricate the moving joints.
