Hi Bow Tie family, I have a 2004 Suburban Z71 with 157,000 miles, I have a grinding noise coming from the front left, at first I thought it was the brakes, changed them and the wheel hub, just before I did the hub I got a ABS light. After changing the hub I still have the same noise. Now a little more description on the noise, it is a grind, but not a constant noise, it kind of wavers, then if I sway the truck back and forth it stops, but then comes back in a few blocks or a few miles. Go ahead and scratch your head I am. By the way I check the back plate and it is not touching. Any and all help is GREATLY APPRECIATED, whether it works or not I file it away because some other poor soul might need it.
