On my 2003 Vibe with 4-spd AT 2WD, I get what sounds like a grinding sound front the front end under very specific conditions. It occurs only under light engine braking (foot off the accelerator) between 40-45 mph and 65-70 mph. It will occur in any gear, but not in neutral. It stops when the steering wheel is turned. Would this be a CV joint? The boots are intact. Any help would be appreciated.

Sound like there is something not balanced...

Second guess (based on readings)

Someone wrote the effects of replacing their regular belt (not timing).

"Once I got the new belt on, the engine was obviously idling quieter, but I'm sure many with the Automatic know of the 35-40mph rough vibrating you get when the car is upshifted and cruising. It's virtually gone now! The car is still sluggish as always (I have AWD btw also) at those speeds but you can comfortable cruise at them without your teeth rattling apart. It's amazing"
