New to the sight and need some help. I have an 05 envoy with 123 thousand miles on it. I have developed a hum in the left front that sounds just like I have agressive mud tires on it. Im pretty sure it is a wheel bearing. I jacked up the front and spun each one by hand and the left side definatley has a faint ticking sound somewhere. I have always been under the impression and in the past that any time you have a bad wheel bearing do the steering wheel shake. I was always told if the noise gets worse when turning left it is a right bearing and turning right it gets worse its the left wheel bearing. In my case here when turning left it gets worse and turning right it goes away. Ive done the steering wheel lock to lock while driving in a circle and have no clicking or clunking from the CV joints so i don't think they are bad. The boots arent leaking and no leaks from the front differential. The fluid is full. I have found these hubs for 300 down to 65 dollars. I know you get what you pay for and one with at least Timken bearings would be the way to go but I am off work for the next 8 weeks with a broken foot and can't afford a good one. Has anyone ever had a left bearing go bad and steered left and got worse. I just don't want to spend a bunch of money right now trying to fix it and replace the wrong part. I rotated the tires just to make sure it wasn't a tire and the noise stayed in the left front. It doesn't change wether its in 2 wheel or 4 wheel drive either. Thanks in advance.
