I recently got given a treadmill and noticed when walking on it, it seems to jolt / slip slightly. It’s not too bad when walking but noticeable when running. I’ve followed advice and lubricated and also adjusted the back bolts for the tightness of the belt.

It does seem to make a random noise that sounds like the belt is rubbing. I’ve attached a video of said noise. Any advice would be appreciated as I’m desperate for this to work. Thank you
