Hi,

I have a 2000 S10 Blazer 4.3 Automatic 180K miles. Looking for a little insight on what could be causing a whining noise. The whining is only heard when coasting (no pressure on gas pedal) 30-70mph. The first bit of gas applied whining goes away. Also noticed when coasting and slight turn on a right curve whining also stops. Not left turn just a right turn/curve. Shifters great and no slipping or sluggishness. Not sure if I'm looking at wheel bearings, something with transmission, a pinion gear or some other issue in drive line. Also feels like there is a bit more force then normal put back on transmission when driving and I let of gas. Any help or "check this" ideas would be great.

Thanks
