2004 blazer grinding noise
Turning at low speeds, especially during a three point turn, get a grinding noise. Sounds like its coming directly underneath the steering wheel. Could that be like the CV axle..? I have no idea. Anyone have any ideas? thanks

Sounds like a wheel bearing.
To test wheel bearings you have to get the tire off the ground. Jack it up and place on jack stands.
Grab the wheel at 12/6 o'clock position and try to rock the tire up and down.
Grab the wheel at 3/9 o'clock and try to move the tire side to side, watch the steering linkage while rocking it side to side.
If you have wobble up and down, more than a 1/16" more than likely that wheel bearing is shot.
Side to side wobble could be a lose ball joint or tierod end, and not likely a wheel bearing.
While you ahve the tire off the ground, remove it and check your brakes. Grinding could also mean that your brake pad is so worn out that the rivet holding the pad to the backing plate is actually grinding away your rotor. Look at your rotor, or run a finger nail across it, if you fel ridges your rotor needs to be ground smooth or replaced. Look at the pads too, how thick are they? If your unsure what they are supposed to look like make a trip the the autoparts store and look at a pair. The pad material is about as thick as your finger. If the pad material you see is about as thick as your finger nail, you need to replace the pad and rotor. Fork over the bucks and get a medium grade rotor, dont buy the 1 year rotor, first hard fast stop will warp. Then your next thread will be why do my brakes sudder when I stop.
