you're fine.
rubber caps on the steering bump stops are gone. it happens. no biggie. either go to toy dealer and get four more or just put a dab of grease on them.
there are four. two for each side.

or leave 'em alone and don't hold the wheel hard to full lock. embarrassing, but won't hurt it.

EDIT,
even if you get new rubber bumper stop caps, lube them. they'll last longer.
