Automobile Engineering | Define wheel alignment and wheel balancing.

Wheel alignment:

• It refers to the adjustment of a vehicle’s suspension the system that connects a vehicle to its wheels. It is not an adjustment of tires or wheels themselves. 
• The key proper alignment is adjusting the angles of the tires which affects how they make contact with the road.

Wheel balancing:

• It is a process that ensures wheel spins truely as they are fitted on a vehicle. In case wheel are not spinning properly then there are problems like uneven tyre wear, a vehicle pulling on one side, excessive bouncing of a vehicle,  wheel shimmy etc which we face. To avoid them this is done.
