When is about Noise, do not believe anything they say in these videos. I've been changing several parts to finish hearing the same noise again, and again. I think is better to take it to the Dealer, not a shop but the real Dealer. I know will be expensive, but they will find the problem and you will not fight like crazy looking for something very hard to find if you don't have a lifter but regular jack stand.
