You can almost always fix this yourself! 99% of the time, it's a lack of lubrication.

1. Identify the Source: Slowly open and close the bleachers and listen for where the noise is loudest. Focus on pivot points, rollers, and guide channels.

2. Clean: Use a brush or rag to wipe away old grease, dirt, and dust from these areas.

3. Lubricate: Use a dry lubricant like a silicone spray or graphite powder. Avoid WD-40 or grease as they attract dirt and gunk everything up worse in the long run.

Spray the lubricant on all the moving parts you identified. Work the bleachers back and forth a few times. The noise should be gone. Do this every 6 months as part of regular maintenance.
