What the thread found

• First remove the Volt and check whether the gimbal is centered without it; most centering issues stem from counterweight imbalance.
• Adding or repositioning counterweights at the trunnion pulley addresses approximately 90 percent of centering problems, with minimal adjustment needed at the outer pan housing; shim washers between counterweight and Volt side can help balance mass.
• Volt kits include additional trunnions that differ only by a few thousandths of an inch in length; swapping trunnions can recenter the gimbal without external service, and manufacturer documentation and community guides are available for this procedure.
• Shimming works but may compromise the fit of the Volt arm (Hockey Stick); one manufacturer flagged user shimming as a warranty issue.
• Complete neutral balance is often avoided in practice; operators report a 6-second fall time is more workable because lens glass shifts during focus, and fully neutral balance caused increased Volt orientation errors in one case.
• Improper pan bearing installation is another possible cause of centering drift.

Depends on

• Whether the gimbal was centered before Volt installation
• Camera weight and lens configuration
• Disputed: self-centering versus returning to manufacturer; disputed whether counterweight/trunnion issues or misaligned pan bearing is the primary cause
