if tightened until there is no backlash the gears would be noisy and get very hot causing them to fail
Backlash is repect to diffrential unit,a gap between the driving pinion and ring gear its called backlash
Backlash in a rear axle is used to allow for a small amount of play between the gears, which is essential for accommodating thermal expansion and manufacturing tolerances. This slight separation prevents binding during operation, ensuring smooth gear engagement and reducing wear on the components. Additionally, it helps to absorb shock loads and vibrations, enhancing the overall durability and performance of the drivetrain. Proper backlash adjustment is crucial for optimal efficiency and longevity of the axle system.
A backlash in a rear axle is necessary to accommodate the slight misalignments and variations in gear manufacturing tolerances between the pinion and ring gears. This small gap allows for proper gear engagement and prevents excessive wear, noise, and potential damage during operation. Additionally, it helps to absorb shock loads and ensures smooth operation under varying loads and conditions. Without adequate backlash, gears could bind or seize, leading to mechanical failure.

Vehicles with front wheel drive have a straight rear axle meaning there is no gear housing in the rear axle. Vehicles that are rear wheel drive have a gear box in the middle of the rear axle to change the rotation of a drive shaft to turn the rear axle. If you look under a full size pick up truck rear axle you will see a large gear box (typically referred to as a pumpkin) in the middle area of the axle. That is the gear box differential.
