A snapping sound often indicates a stretched transmission cable. In Docklands, we replace these with steel-core timing belts that resist stretching. We also inspect the carriage wheels. Replacing worn rollers eliminates vibration, allowing the door to glide effortlessly.
The heart of your system in Docklands is the High-Torque Drive Unit. When these fail, you might hear grinding noises. We diagnose specific faults like stripped nylon gears and replace the unit with OEM parts to restore factory performance.
