If you just replaced the running belt, then "thumping" noise is fine - it does come from the running belt seem running over the roller. Running belt usually wears in in about two weeks. Unless you replaced the running belt a while ago...

Now the treadmill has this "thumping" noise when I run on it. My husband thinks it is from bearings in the rear roller going bad. I haven't been able to find a rear roller for this treadmill and have been searching pretty dilligently. Does anyone know if the whole roller has to be replaced as a whole unit or if the bearings are replaced separately--or if this doesn't sound like a bearing issue.
It is part number Z81TM06-009 Rear Roller Set.
