im assuming the whining is the tod doing its thing and mine does it much less if i have all 4 tires EXACTLY the same psi, but i also get a bit of a grab and a slight clunk when coming to a stop, then a drop when i let off the brakes - im assuming its something binding inside the diff or brake systems doing something weird, but depending on how i drive it gets worse and better all the time - ive found threads in the archives of people buying their vx's brand new and having the same experiences so im not so sure it couldnt be an engineering flaw, but either way im not really worried about it
