What the thread found

• A clicking or clunking sound during tilting motions in an Ultra2 gimbal can indicate loose components in the fore-aft drive mechanism, particularly around the adjustment knob area.
• Excessive play in the top stage (less than 1mm but noticeable) may cause balance shifts during large tilt movements, particularly after the rig passes horizontal during rotation.
• The fore-aft adjustment knob contains a hex nut beneath a rubber cap that can loosen and should be checked and tightened with care.
• Some bearing movement in the gimbal during extreme tilting is considered normal by manufacturers, but clunking sounds occurring at 60-70 degrees of tilt may indicate additional mechanical issues requiring inspection.
• Tightening accessible screws throughout the gimbal assembly may not resolve fore-aft balance issues if the root cause is internal play in the adjustment mechanism.

Depends on

• The original problem report was from 2009 on an older model (Ultra2c).
• The manufacturer ultimately stated the clunking noise was normal behavior, but this conclusion was disputed by the user who noted their Archer steadicam did not exhibit the same behavior.
• The exact cause was never definitively identified or confirmed in the thread; the user reported improvement after sending the rig for inspection but underlying issues persisted.
• Access to the fore-aft adjustment screw is difficult and requires disassembly with risk of damage.
