What are the steps for replacing a half-shaft oil seal?

[LaArabella]

First, remove the tire, then take out the fixing screws at one end of the half-shaft, unscrew the triangular fixing screws of the lower control arm, and finally dismantle the transmission end screws of the half-shaft to proceed with the replacement. Below is relevant information about the half-shaft oil seal: 1. The half-shaft oil seal is located at the lower part of the chassis. Its function is to seal and separate the positions between the drive axle and the wheel-side reducer. The half-shaft is used to transmit the output torque from the differential's half-shaft gear to the drive wheel or wheel-side reducer. 2. If the half-shaft oil seal leaks, it will reduce the amount of lubricating oil in the drive axle, affecting normal lubrication and accelerating the wear of components, leading to premature damage. Leakage of the half-shaft oil seal allows lubricating oil to enter the wheel-side reducer, causing the oil level in the wheel-side reducer to rise, which can damage the oil seal. The oil may then flow into the brake drum, resulting in poor braking performance and posing a safety hazard while driving.
