"sinking" vehicle engine

I have made a custom engine for one of my land vehicles. the engine is tank like, but doesn't have the tread on it. the engine is 2 "treads," and each tread is 2 willy wheels, one front, one back, and 3 sherman dummy wheels between them.

To the point, the vehicle is okay empty, but when I enter the vehicle and try to drive it, the wheels collapse and the vehicle bottoms out. When I get out, the vehicle goes back to normal. What in the blood happened?

Check your springs. The spring strength and the damping.

The 4 drive wheels have a strength of 50, and a damping of 5. the mock wheels have strength of 0, and damping of 0. The vehicle has a mass of 2500.

Check the wheels for a collision mesh,
check to see if the wheels are attached to the engine and not the vehicle,
I'm out of ideas.

Well, it was really just the order the wheels were attached. The left tread right tread thing messed it up. Adding each wheel individually to the engine fixed the problem.
