Eliminating creaking noise from a Pro arm
What the thread found
- Creaking can originate from the connection between the plate holding the socket block and the center upright spar, which can be resolved by disassembling, cleaning, and reassembling that joint
- The canister draw bar (piston) held by a single stainless steel screw under load should be lubricated with white lithium grease
- Cleaning the two pins and their mating surfaces on the chassis can eliminate creaking
- Loose bolts connecting the arm together, including both Allen wrench bolts and pin spreader bolts, can cause creaking and should be checked and tightened
Depends on
- The exact location of the creak is difficult to pinpoint, making systematic troubleshooting necessary
- Multiple potential sources exist and the solution may require trying several approaches
- Maintenance advice is specific to Pro arm and Pro vest models
