All - I have an '08 GS460. Since purchase, when making right turns into inclined driveways, the car would literally "pulse" when pulling into the driveway. Occasionally, the VCS light would come on. I am never going more than 5mph when this occurs Recently, I have decided to turn off the VCS "nanny" as I like the improved throttle responses. However, now when pulling into these same driveways I hear a loud "metal to metal" clunk from the rear and still get a reduced hesitation. I can feel the clunk throughout the car. Does anyone have an idea????

i can't say much about the metal clunk neither, did you try to turn back on the vsc and see if it goes away
the hesitation is probably because when you turn into driveway, your right rear wheel got "lifted". and since we have open differential, that wheel is considered "slipping" and vsc kicking in.
without vsc, then the lifted wheel should keep on spinning, maybe that that time the car is rolling back and forth a bit and the suspension adjusting?

Yeah I was referring to the clunking not the wheel spin.

The clunk definitely goes away, but the "pulsation" or "hesitation" while making the turn doesn't... so I have a choice, the clunk or the pulsation. Clunk has me most worried. I'm trying to tape the sound, but it's not working....
