I've had a Sportcraft TX 2.5 treadmill for 3 years. It still runs great, it has just developed this terribly squeaking when I run on it. Its just getting worse. I have made sure it is sitting level. I am 160 lbs, so I dont think thats too much. It seems to have something to do with the belt.I have looked for a place to grease it, but not sure..Anybody experiencing this?
