So, In just bought a used set of challenger rollers, and when I started using them, the front drum is really loud.

The noise is coming from the vibration of the drum and rattling the frame of the rollers. I put shims in between the frame and the attachment to prevent movement (read: rattling), and that helped a little, but there is also a ton of noise being generated by the actual drum itself. Sometimes it will run smooth, but other times it will generate a lot of noise and vibration.

I have it set on carpet to reduce vibration noise (especially considering i live in an apartment with people below me). They must hear these things, as it is pretty darn loud.

I have thought about getting some plywood as a base to put down on top of the rug, to further insulate the vibration noise, but ideally i would like to find a solution to the actual problem as opposed to working around the problem.

Could the drum be out of round? I thought these things were supposed to last forever. The person I bought them from only used them one season, and they are only two years old.

Thoughts, ideas...? Anyone with similar problems?

Sounds like the bearings are bad. Take the drums off and spin the axle by hand and feel the motion. It should be smooth with no free-play in any direction...
