Front end issues
 

I own a 2004 a4 b6 1.8t, recently brought it from funk flex mechanic; so far i changed the motor mounts and turbo gasket but now there's a hard knock when i get to speeds of 40-60 mph plus my front right hub bearing is starting to go or has already. My question is what could cause the hard knock and does anybody know any places in Westchester where i can get the car fully checked out?
