In addition to changing the oil during maintenance, remember to check these 4 parts

1. Universal joint

The universal joint is a key component in the vehicle transmission system, which has a sealing and protective function. It mainly protects the rubber sleeve of the ball cage to prevent dust from entering. If the vehicle has problems such as violent shaking or abnormal engine noise, it may be caused by oil leakage from the ball head oil seal. In serious cases, it may even cause traffic accidents. Therefore, vehicle owners should pay attention to the condition of the universal joint during maintenance and replace damaged parts in time.

2. Brake calipers

Brake calipers are an important part of the brake system and are in direct contact with the ground. After long-term use, brake calipers may become worn and rusty. This may cause problems with vehicle tires, affect braking function, and increase fuel consumption. Therefore, during maintenance, car owners should check the condition of the brake calipers and replace severely worn parts in a timely manner.

3. Brake Cylinder

The brake cylinder is an important component in the vehicle's brake system, but it is often overlooked during maintenance. Since the brake cylinder needs to be in direct contact with the brake fluid, it is prone to failure, such as poor braking effect, wheel locking, etc. During maintenance, owners should pay attention to the condition of the brake cylinder to ensure that it works properly.

4. Spark plugs

The spark plug is a key component in the engine, responsible for igniting the mixed gas to drive the vehicle. If there is a problem with the spark plug, it may cause symptoms such as lack of power and difficulty in starting. Therefore, during maintenance, the owner should check the condition of the spark plug and replace the damaged parts in time.
