Which is a step in proper chassis lubrication?

• A. Wipe the fitting clean with rag and press lubrication gun end to the fitting.
• B. Apply lubricant to the entire engine block
• C. Skip cleaning the fitting if in a hurry
• D. Lubricate only after engine heat up

Answer: (A)

The key idea is to ensure the grease fitting is clean and actually receives grease. Wiping the fitting with a rag removes dirt and old grease that could contaminate the joint, and then pressing the end of the grease gun against the fitting creates a secure seal so the grease is forced into the fitting and into the bearing or joint. This direct, clean injection is what makes the lubrication effective and helps prevent grit or debris from being trapped inside. Other options miss the point: greasing the engine block isn’t addressing the chassis fittings, skipping cleaning invites contamination, and waiting to grease until the engine is hot isn’t a required rule and can miss proper lubrication timing.
