After a couple of light collisions my "sprite" 4 wheel drive RC car fishtails and (spins in a circle) when accelerating. It has been totally submerged in a giant mud puddle accidentally by my son. It was cleaned up, dried and it started 1st go. When holding the car off the ground the rear wheels spin and not the front wheels. I gave the car a good clean and couldn't see anything obvious, like a broken drive shaft??

Where could the problem lie?

if it has a center differential, take that out and open it to make sure none of the gears are shredded

I did find there was a problem with the gears that are supose to freewheel one way and lock in in the reverse direction. I replaced the gear assembly and I am sure will solve the problem, Thanks for the clues.
