Fluids are all good. Yes , I agree, there is a clunk when going from P through R to D, however as soon as I started to roll forward the un-usual clunk occurred. No noises when turning= CV's probably ok.
Noise stopped, hasn't occurred since..........stumped.

Bmrdude did pass the time by typing:
Try this.
Engine running, foot on the brake. Put it in drive, give it some gas foot off the gas, put it in reverse and give it some gas. Then do the same going into drive.
(don't floor it, just strain the engine a bit against the brakes)
That will put a bit of strain on the driveline and make any weak or failing U joint sound off.
There are other possiblilities including a broken tooth in one of the diffs but usually that makes a real bad grinding noise you can feel.
Was the clunk equal with wheel speed or was it faster?
equal with wheel speed
Bmrdude did pass the time by typing:
- rock in tread
- lump of ice in rim
- board/nail/etc stuck to tire
- very cold tire flat-spot (uncommon)
- diff
The driveline will make noise at about twice the rate than the wheel moves due to gear reduction in the diffs. The only reason I mention diffs is the outer ring gear also rotates at tire speed. IF you have a limited slip rear and it's very cold they can stick till warmed up.
