Problem: Rear annoying sound that disappears after driving ~5 minutes at high speed.
Solution: Multiple diagnoses suggested: brake drum adjuster (NODES2K), loose brake component causing ratcheting when turning wheel (yueciHH), or clutch electric actuator (deleted user). Scott_Delaney suggested removing brake drum to diagnose. No confirmed fix reported.
