Poor quality part made some soft metal. Although it is genuine OE coupling but after just 1500 miles ticking noise came back to the engine. We stripped the balancing unit again and we found significant wear on this new coupling. A few months ago we replaced this worn OE coupling with the Zedperformance brand found on Ebay which is still quiet and no noise at all. That seems to made of much harder material than this OE balance shaft coupling.
