Ya' think since he can hear it in reverse, that it's still the bearing? Seems to me ya' don't hear bearings till about 20 - 25 mph.

I thought I had the turtle gears there, grest, but the build codes show one even slower than that (courtesy of lees):

The noise has been buggin me for about a year now. It's not loud by no means,just annoying when I'm by my self driving. by the way, where did you come up with the code list. I have been trying to decode my Vette since I bought it. Thanks[sm=exactly.gif]what I have been lookin for.

 

I have always tried to get good gas mileage with most of the cars I have had over the years. But let's face it, what's a Vette that can turn on a dime and not enough power to take a Viper or whatever.[sm=badbadbad.gif]I have gas savers, this is not going to be one. I wantthe Vette to do that sometime down the road. One I can drive daily like I do now. You know ,a sleeper, you do not know it's there untill it is to late.[sm=crossbonesgif.gif] The 3.42 or 3.72 sound good to me. I need to find out what rear end I do have then I will decide.

 

LEESposted it up when I was tryin' to figure out what some part was...
