I am thinking of greasing up the moving parts near the pedal because I hear a strange noise when I step on the clutch pedal. Which do you recommend, regular LS Bell hammer spray or grease (No.0 or No.2)?

LS Bell Hammer or LS Bell Hammer Gold spray type can be used for maintenance by applying it through gaps without disassembling the moving parts.
If you want to maintain it well, we recommend grease No. 0, which is softer than No. 2, but contains more oil and grease and retains more oil and grease, so it can reduce noise.
