A final drive pinion is a gear component in a vehicle's drivetrain that works in conjunction with the ring gear to transmit power from the driveshaft to the wheels. It is typically located within the differential assembly and plays a crucial role in reducing the rotational speed and increasing torque. The pinion gear engages with the larger ring gear, allowing for smooth power transfer and helping to achieve the desired wheel speed. Proper functioning of the final drive pinion is essential for optimal vehicle performance and handling.
With shims in most cases.
The rack and pinion effects the steering of the vehicle directly. It is definitely not recommended to drive a car with a bad rack and pinion because of this.
There is a special lock nut, inside the final drive that has to be removed. This requires a special tool that is very hard to find.
To calculate the final drive gear ratio, divide the number of teeth on the driven gear (typically the ring gear in the differential) by the number of teeth on the driving gear (usually the pinion gear). For example, if the ring gear has 40 teeth and the pinion gear has 10 teeth, the final drive gear ratio would be 40:10, which simplifies to 4:1. This ratio indicates how many times the driveshaft must rotate to turn the wheels once, influencing acceleration and top speed.
During final assembly.
No, you risk having a accident. The rack & pinion is what is used to steer the car.
Best left to a mechanic as the drive shaft has to come down and the big nut on the pinion gear that holds the drive shaft mount has to come off and then you can install the new pinion seal.
A pinion is a grooved gear that attaches to the drive shaft of a vehicle. This is a major component in the steering and suspension system of a vehicle.
The teeth are usually provided on the pinion of the spur wheel, to drive the spur wheel.

They are used to check pinion and ring gear alignment. If you apply paste to the ring gear and spin it and have a pattern to close to the outer edge(toe) you would need more/thick pinion shims. A heel pattern would be the oposite.
to replace pinion shaft seal you need to drop the drive shaft from the rear end then with large socket remove pinion nut from front of yoke remove yoke remove old pinion seal install new pinion seal reinstall yoke and pinion nut to specified torque re install drive shaft note now is the time to check and see if U-joints need replacing
