To install a new M4 thread shaft, follow this process carefully. First, locate the old shaft and remove it by gently pulling it out of its housing. Once removed, inspect the area for any debris or leftover threads. Next, clean the area thoroughly with a soft brush to ensure a smooth installation. Now, take the new M4 thread shaft and align it with the housing, ensuring it is seated properly. Hold the shaft firmly in place and insert a small amount of lubricant into the threads. Finally, screw the shaft in clockwise until it is securely tightened.
