Oh god, this brings back bad memories. Not my SVX, but a close friend's that I was the last one to drive it on the road. Is it one loud hard clunk every time the tire makes a full rotation? If so, in our case it was when the front differential went. If I remember correctly, every time it clunked, it also gouged the inner surface of the one front wheel in the same spot. You don't have it in FWD mode do you? When the front diff went in her car, "park" didn't do a damn thing, just rolled like it was in neutral.
