So yeah...Ive been noticing lately that Im getting a loud humming noise from about 60-70mph. It goes when I turn the wheel different ways but comes right back when Im going straight. Im pretty sure Ive got a wheel bearing going bad, and I THINK its my drivers side...but not 100% sure. Whats the easiest way to find out which one is bad? and is there a company out there that sells aftermarket wheelbearings that are any stronger than the factory ones? Im currently running all Moog parts that were changed out last summer (Balljoints, Idler Arm, and Pitman Arm). Any help is appreciated. Thanks :handshake

Jack up the front end. Grab the tire at 12 and 6 and push and pull. If you have free play thats your bearing. I know when my left went bad, I had little play but when I spun the tire it was incredibly noisy. Not sure about any tougher than factory but you will have to replace the entire hub assembly as Chevys dont have serviceable wheel bearings.

That test could also indicate balljoints.
it would if you were to jack it up underneath the LCA, the weight of the vehicle has to be on the LCA to check them....best bet is to spin the wheel by hand and listen for noise, but its not always the case

from what you said about the noise going away when you turn the wheel, which direction? Usually, turning to the left and having the noise get louder would indicate the right side bearing being bad and vice versa

Actually the noise goes away when turning both directions...doesn't really get loud or louder till I hit around 65mph...
