In this video I show how I change a VVT-I cam gear in a 2009 Toyota Corolla. Reason for this repair is a rattle noise at startup from the timing chain. This is a problem that most Toyota Corolla and other similar models with the 2zrfe engine may encounter. I initially installed two cheap Cam Gears that I purchased off of ebay. They were JUNK and did not solve the issue. I took the original gear apart and pinched the springs tighter and re-assembled. This did correct the issue.
