Why are correct fluid levels important in the final drive assembly?

Correct fluid levels in the final drive assembly are crucial for optimal lubrication and cooling of the gears and bearings. Insufficient fluid can lead to increased friction, overheating, and accelerated wear, potentially resulting in catastrophic failure. Conversely, overfilling can cause foaming and pressure issues, compromising performance. Maintaining the proper fluid level ensures efficient operation and extends the lifespan of the assembly.
