What Causes Oil Leakage from the Rear Wheels of Large Vehicles?

Oil leakage from the rear wheels of large vehicles is related to the axle head oil seal and the rear axle breather valve. The issue may arise from a damaged wheel hub oil seal or a clogged rear axle breather valve. Potential Hazards: This can lead to ineffective braking, vehicle deviation, and increased gear oil consumption. If the rear axle leaks oil over an extended period without regular checks on the gear oil level and timely refilling, it can cause premature wear of components such as the differential and reduction gears. In severe cases, sudden failure may occur while driving. Additionally, if gear oil from the rear axle flows into the brake drum via the wheel hub, it may wash away some of the bearing grease, leading to insufficient lubrication of the wheel hub bearings. This can result in the erosion and damage of rolling elements or protective rings. Troubleshooting: Upon discovering gear oil leakage from the rear wheels, promptly identify and address the root cause. If the breather valve on the rear axle housing is clogged, replacing it in time can resolve the oil leakage issue. First, verify whether the leaked oil is indeed gear oil before taking appropriate measures. If it is gear oil, check the oil level. If the rear axle gear oil is not excessive, focus on inspecting the rear axle breather valve. Should the breather valve be clogged or damaged, repair or replace it to eliminate the fault.

How much fuel can actually be added to a 58-liter fuel tank?

A 58-liter fuel tank can actually hold up to 70 liters of fuel, because the labeled capacity of the tank is not the actual maximum capacity, but the maximum reasonable capacity. A standard fuel tank can typically hold an additional 10% to 15% of gasoline or diesel beyond its labeled capacity. Below is some relevant information about automotive fuel tanks: Definition of a fuel tank: A fuel tank is a container used in vehicles such as cars or airplanes to store fuel, and it is a specialized container in hydraulic systems for storing hydraulic oil. Function of a fuel tank: In addition to storing gasoline, a fuel tank can also dissipate heat and separate air bubbles from the oil. Fuel tanks can be divided into two types: open tanks and closed tanks.

What Are the Symptoms of Water in the Fuel Tank?

Symptoms of water in the fuel tank depend on the amount of water ingress, with specific symptoms as follows: Shaking: When water is delivered to the cylinders, it affects gasoline combustion, leading to increased cylinder carbon deposits, engine backfiring, and shaking. In severe cases, it can cause the car to stall or fail to start. Insufficient Power: Incomplete gasoline combustion directly impacts the car's power, resulting in high idle speed, insufficient power, and weak acceleration. Damage to the Fuel System: Water in the fuel tank can cause rust in the tank and fuel lines, leading to blockages that affect fuel supply. In severe cases, it can also damage other mechanical components.

Can Scratches from Tree Branches on a Car Be Fixed?

For minor surface scratches, you can apply scratch wax or polishing wax to a towel and repeatedly rub the scratched area to address slight scratches. Toothpaste contains abrasives and can be used for small damaged areas and minor scratches. Use a touch-up pen for repair. Touch-up pens are a commonly used tool for car owners to fix scratches themselves. Fine sandpaper can be used for grinding followed by polishing to resolve the issue. If the scratch is deep and has exposed the primer, the better solution is localized paint repair.

Should You Ignite the Engine or Shift Gears First When Driving?

Whether it's a manual or automatic transmission car, the engine must be ignited first when starting the vehicle. Starting an automatic transmission car: Turn the ignition key to the second position, the power gear, allowing the car's computer system to begin self-checking for at least 6 seconds or more. Step on the foot brake, shift the gear from P to N, release the foot brake, turn the ignition key to the ignition position to start the engine. Step on the foot brake again, release the handbrake, shift the gear from N to D, and slowly release the foot brake to start moving. Starting a manual transmission car: Insert the key into the ignition lock, turn on the ignition switch, and observe whether all instruments are working normally before starting the engine. If any instrument is not functioning properly, immediately turn off the engine and check and resolve the issue before restarting. Press down the clutch pedal, shift the gear lever into the 1st gear position, turn on the left turn signal, honk the horn, and observe the front, sides, above, and rearview mirror for any obstacles that may hinder starting. Release the handbrake, hold the steering wheel steady, gently lift the clutch pedal with your left foot until the clutch is in a semi-clutch state. The height of the semi-clutch position varies depending on the clutch's sensing point, generally between 30-45 degrees. The vehicle will start to vibrate slightly, indicating that there is enough power to start moving.
