Left Crank Arm (Non-Drive Side)
The non-drive side crank arm is statistically the most common point of failure for looseness. Once the aluminum internal splines are deformed by movement against the steel spindle, the part becomes unserviceable and must be replaced to ensure a secure mechanical connection.

Right Crank Arm (Drive Side / Chainring Side)
The drive-side arm is subject to the same mechanical loosening via fastener back-out. Replacement is required if the internal mating surface has suffered plastic deformation, which prevents the arm from remaining seated during high-torque intervals.

Crank Arm Retention Bolt
This fastener provides the axial clamping force required to hold the arm onto the spindle. Over time, threads can stretch or the factory thread-locking compound can fail, leading to a loss of pre-load that causes the arm to feel loose.
