XRAY 007' Diagnostic Issue

XRAY 007' Diagnostic Issue
I just finished building the 007 last night and noticed a couple things that are bothering me and I am trying to find out if it is normal.
1) The diffs front and back wobble when they are not tight. If I make them tight then they are locked up which is no good so my question is are they supposed to wobble. Check yours by grabbing the center of diff
and shaking side to side and see what I am talking about.
2)If I turn any one of the wheels by using my finger on the face of the rim and making a complete circle, a ticking noise can be heard from the wheel area. It is doing it on all four wheels and it doesn't seem like anything is binding, is this noise normal?
3) When driving the car on a flat surface and watching the rear of the car driving very, very slow, the entire back of the car wobbles from one side to the other, any ideas?

1) Normal.
2) its the pin in the layshaft that locks the pulleys in place. It will slide back and forth making this noise....No harm in it though.
3)No clue but I dont think you'll see it on the track. Just run the car and be fast

Thanks for all of the input guys except the first guy who doesn't know a good car when I run him over with one. The car wobbles on solid wood floor, I have the tires trued so I will look into it further when I am home from work in two hours. What lay shaft pin are you talking about? The ones under the teeth for the two gears next to the spur gear? I had another thought about, I think some loctite from the set screw in the cvd may have gotten into the joint causing the snapping noise, and yes it sounds twice per revolution.
As far as the diff goes, i thought it was normal but just wanted to be sure!

Yes the two pins in the layshaft that lock the 2 pulley gears in place. The reason its twice per revolution is it's flopping from one side to the other....therefore 2 clicks per revolution. Very annoying but not harmful

foam tires eh? Do you happen to have the shocks in the outer most hole on the rear arm? Most 28mm plus rims will rub the lower end of the shock. i think it happens at the front too with wide foams.
NEXT EVOLUTION OF SEDANS PLEASE:
-no clicking cvds at full lock
-if u make a foam car let it run foam tires out of the box at all shock locations
-drop kick the price downward!

To get rid of the clicking noise caused by the layshaft pins, I just put a small amount of thick grease on the 12mm pins before putting them in the layshaft .

I figured it all out, the clicking noise turned out to be the rear hubs hitting the rear arms from moving foward and backward, seems like normal play. If you grab the rear hub you can move it a little from front to back and watch it click the rear arms, probably need that play so it won't bind. The wobbling was the rear tire on the right side was broke but didn't see it and the diff play is normal.
