I would guess the problem is with a diff. You've worn out one of the gears or something. Try a few of these things;

1) If you spin the back wheels (hold them both and spin them the same direction, together) do the front wheels move?
2) Can you see the rear dogbones turning as you do Step 1? if not the problem exists in your wheel hubs
3) Can you see the dogbone connecting the rear diff to the centre diff turning as you do Step 1?

Just a few things to check first up.

My guess would be in the following order.

- You've stripped the rear pinion gear (part 02030 - Drive Gear) according the manual.
- you've stripped the gears inside your centre diff.
- lastly, it's a bit of a fluke that it'd happen to both wheels at the same time, but you may have lost the pin that hold the out drives of the wheels, to the wheel hubs. So basically if you turn the wheels, only the wheels spin, and not the dogbones and such.

Would be interesting to find out the outcome though. Keep us posted
