What the thread found

• Vibration appearing primarily at longer focal lengths may originate from the sled or camera setup rather than the arm itself
• The central post on a Zephyr is prone to flexing, which can be minimized by avoiding extension
• Loose screws around the post beneath the stage can work free over time and cause vibration problems
• V-lock battery mounts and camera plates should be inspected and secured to eliminate play
• Adding mass to the lower sled and reducing post extension can help reduce vibration
• A rigid monitor yoke and soft velcro padding on mounts can improve stability of the camera stage
• Aftermarket rigid monitor yokes may introduce their own resonance characteristics depending on setup
• Vibration issues can be intermittent and difficult to reproduce, making isolation challenging

Depends on

• The original poster did not complete the service request with Tiffen, so the quality and scope of their repair diagnostics remain unknown
• The intermittent nature of the vibrations suggests they may be dependent on specific operational techniques or weight distributions that were not fully documented
• Testing was limited to one practice weight cage setup of approximately 12-13 pounds
• The relationship between the growing gap in the quick release mechanism and the vibration was not conclusively determined
