3. Rotate the pulleys around the smooth bar and tighten the set screws, avoid fixing the set screw over the initial position.

If the noise is coming from the front pulleys, slightly lose the M8 Allen screw, and apply some lubricating oil to both the screw and the pulley. Then tighten the screw again.
