Undercarriage animation

I have a nose gear consisting of the main leg, lower leg, wheelsteer and two wheels. When I get them all in position and start allocating the correct names, they jump all over the show.
I am now getting tired of searching for the parts and trying to put them together again.
What is the correct way of doing this -- is there a specific sequence of events, or what ?
