Does Removing the Half Shaft Require Draining the Transmission Fluid?

[BrynleeDella]

Removing the half shaft oil seal requires changing the transmission fluid. Below is relevant information about the vehicle half shaft: 1. The half shaft, also known as the drive shaft, is the shaft that transmits torque from the transmission reducer to the drive wheels. It has a universal joint at each end, which connects to the reducer gear and the hub bearing inner ring via splines on the universal joint; 2. Transmission fluid is a lubricant that keeps the gear system clean, ensuring the transmission operates normally and extending the lifespan of the transmission components; 3. Most transmission fluids can be used in automatic transmissions available on the market. However, each automatic transmission design has different technical requirements. Even the same model of transmission configured in different vehicle models will vary in torque, weight, speed, structure, etc. Therefore, the original manufacturer specifies its own dedicated transmission fluid.
