He mentions the plan to place it back onto the top stud and start the bolts, suggesting an attempt to re-engage or partially reassemble the component.

Goal: After identifying the extension piece, the mechanic notes that it is not detaching easily today. He cleans the piece slightly, intending to mount it back onto the axle's first stud and start the bolts.
