Creating a car

Hey everyone,
I’m fairly new to the Game Engine, and I want to create just a muck-around car game. Obviously to get the car to turn realistically, I need to keep the wheels as seperate objects. The problem is, I’ve made the car body a parent to the wheels, but when I start the game, the wheels just fly away. I don’t know what to do - is there some way to keep an object ‘attached’ to an object besides parenting? :confused:
Thanks in advance.

EDIT: Sorry if it’s a really obvious answer… :o

Hello
In a normal situation, objects don’t fly away even when parented!?
Go here and download the physics testfiles, there’s already a great
vehicle setup inside:

Thanks.
BTW, it’s not cos it’s parented that they fly away, it’s because they are too close.
