Hello - my reformer is 2 months old. I hear a slight “popping” sound on the left side when I push out the carriage. I checked and cleaned the wheels and tracks and all appears good. Could you please advise on the cause and how to resolve it?

A slight "popping" sound on the left side of a Merrithew Reformer when pushing out the carriage could be caused by a loose or worn spring, spring bolt, spring clip, or pulley component. To resolve it:

1. Inspect all springs for wear or damage and replace if needed.
2. Check that spring bolts and spring clips are securely fastened.
3. Inspect traveling pulleys and ensure threaded bolts are secure.
4. Perform monthly and yearly maintenance as recommended, including replacing spring clips yearly and springs every 24 months or as needed.

Proper maintenance and secure fastening should eliminate the popping sound.
