2. Protecting Against Contamination Wheel oil seals act as barriers against external contaminants. Dust, dirt, and moisture can enter wheel assemblies if seals fail, leading to corrosion and degradation of components. Keeping these harmful agents at bay is essential for maintaining the health of the vehicle.

A coil spring is a mechanical device which is typically used to store energy and then release it, to absorb shock, or to maintain a force between contacting surfaces. They are made of elastic material that forms a spiral shape and returns to its natural length when unloaded. Under tension or compression, the material (wire) of a coil spring is subjected to twisting. Therefore, the spring properties depend on the shear modulus, not on the Young's modulus.
