Damaged rear axle bushings can affect body shaking. When the rear axle bushing is damaged, it loses its ability to absorb shocks, leading to vibrations and unusual noises from the chassis. Severe vibrations can compromise the stability and comfort of the vehicle while driving. The rear axle bushing acts as a flexible buffer between the axle and the sleeve. A damaged bushing may also cause collisions between the axle and sleeve, potentially leading to misalignment of the rear wheels and wheel arches, as well as abnormal tire wear. Steps to replace the rear axle bushing: 1. Lift the vehicle; 2. Remove the two rear axle screws and oil pipes; 3. Use a specialized tool to pull out the old bushing; 4. Apply lubricant to the new bushing and install it.

A failed rear axle bushing will definitely cause body sway. As the bushing serves as the suspension's damping pad that connects the rear axle to the vehicle body and specifically absorbs road impacts, once it's damaged or aged and loses its cushioning effect, the rear axle cannot remain securely fixed. When encountering turns, bumps, or acceleration while driving, the body—especially the rear—will noticeably sway side to side, creating a strong sense of instability. I experienced this with an old car of mine—the swaying was so severe on the highway it was nerve-wracking, and later I noticed squeaking noises. Upon inspection, the bushing was cracked. After replacing it with a new one, the swaying disappeared, and the ride became much smoother. This issue can also lead to chain reactions, such as excessive tire wear or additional stress on suspension components, making long-term neglect even more dangerous. It's advisable to regularly maintain and inspect the bushing's condition and replace it promptly to avoid trouble—safety should always come first.

What are the reasons for the diesel high-pressure fuel injection pump not delivering oil?

There are several reasons why the high-pressure fuel pump may not deliver oil: the auxiliary shutdown switch is in the connected state; the rail pressure is too low; the battery voltage is too low; the synchronization signal is incorrect. The working principle is as follows: 1. Suction stroke: During the suction process, the downward movement of the pump piston provides the power for suction, while the intake valve opens, allowing fuel to be drawn into the pump chamber. In the last third of the pump piston stroke, the fuel pressure regulator is energized, keeping the intake valve open during the initial upward movement of the pump piston to allow fuel return. 2. Return stroke: To control the actual fuel supply, the intake valve opens during the initial upward movement of the pump piston, allowing excess fuel to be pushed back to the low-pressure side by the pump piston. The pressure damper absorbs the pressure fluctuations generated during this process. 3. Pumping stroke: At the beginning of the pumping stroke, the fuel pressure regulator is de-energized, causing the intake valve to close under the combined action of the rising pressure in the pump chamber and the closing spring inside the valve. The upward movement of the pump piston creates pressure in the pump chamber, and when this pressure exceeds the pressure in the fuel rail, the outlet valve opens, allowing fuel to be pumped into the fuel rail.

What is the Scrapping Age Limit for Motorcycles?

National regulations stipulate that the service life of two-wheeled motorcycles is 10 years, which can be extended by 3 years. However, during the 3-year extension period, semi-annual inspections are required, and the extension is only permitted upon passing the inspection. After reaching 13 years, mandatory scrapping must be implemented. Below are key points regarding the proper use of motorcycles: Vehicle Starting: When starting the vehicle, it is essential to complete the self-inspection and aim for an immediate start. If the first ignition attempt fails, pause briefly before trying again. If the motorcycle fails to start after three consecutive attempts, cease further ignition attempts and investigate the cause. Vehicle Warm-up: During warm-up, avoid randomly revving the throttle; simply let it idle for two to three minutes. In summer, this duration can be slightly shortened. The benefit of warm-up is that it allows various parts of the engine to quickly reach optimal lubrication conditions, preparing the vehicle for normal starting and riding. Vehicle Take-off: Locate the engagement point of the clutch and hold it steady, then gradually apply throttle while gently releasing the clutch to complete the take-off operation.
