Reinstall the front wheels and lug nuts and lower the car to the ground. Once the vehicle is at a normal riding height, torque the lug nuts and control arm mounting bolts according to their proper torque.
Gravity is a function of mass. It is the enormous gravitational influences that causes nuclear fusion within stars. Explanation: If you accept, as you must, that gravity is the causal factor of nuclear fusion in all stars then you can infer by extension that the larger the star, the greater the mass; the greater the mass, the greater the gravity; the greater the gravity, the faster the rate of nuclear fusion.
Greater gravity compresses the gas, making it denser and hotter, so the outward pressure increases. In any given layer of a star, there is a balance between the thermal pressure (outward) and the weight of the material above pressing downward (inward). This balance is called hydrostatic equilibrium. A star is like a balloon. In a balloon the gas inside the balloon pushes outward and the elastic material supplies just enough inward compression to balance the gas pressure. In a star the star's internal gravity supplies the inward compression.
