We have a 2008 Tahoe LTZ. When we are slowing down not necessarily braking but in the 20-30 mph range we get a noise that appears to come from the front drivers side. It is not a grinding noise more of a rattle almost plastic sounding. I have replaced wheel bearing and cv shaft on drivers side and still have noise. I have beat on just about everything under it and can't seem to narrow down. Anyone else have or have had this issue?
