What are the symptoms of a bad rear shock absorber?

The symptoms of a faulty shock absorber are as follows: 1. Shock absorber oil leakage. A normal shock absorber has a dry and clean outer surface. If there is oil leakage, it indicates that the hydraulic oil inside the shock absorber has escaped from the upper part of the piston rod, meaning the shock absorber is basically ineffective. 2. When the car passes over bumpy roads or speed bumps, a certain wheel makes a "clunking" sound, indicating that the shock absorber on that wheel has poor damping or is ineffective. 3. When the car is cornering, there is a noticeable increase in body roll, and in severe cases, even skidding may occur. This is mainly because the damping force of the shock absorber is too small to effectively suppress the compression of the spring. 4. After driving on rough roads for a while, touch the outer shell of each shock absorber to feel its temperature. Normally, the outer shell of the shock absorber should be warm. If a shock absorber's outer shell is cold, it indicates that the shock absorber is damaged. 5. When the car is stationary, press down on one corner of the car body and then release it. The body will rebound under the force of the spring. If it stabilizes quickly after rebounding, the shock absorber is intact. If it oscillates several times before stopping, it indicates poor damping performance of the shock absorber.

When the rear shock absorbers of my car failed, the first thing I noticed was that the ride became particularly bumpy, especially when encountering potholes or speed bumps on the road. The car bounced up and down violently, making rear passengers complain about discomfort. When taking turns at higher speeds, the rear of the car would sway severely, feeling unstable like skating on ice, which made my palms sweat. Driving over uneven surfaces also produced loud "clunking" or metallic scraping noises from the rear. Additionally, the tires showed uneven wear, with the outer edges wearing out faster upon inspection. On highways, the bumpiness became more pronounced, affecting steering control and requiring me to slow down to maintain stability. Driving like this for extended periods was both exhausting and unsafe, so I promptly took the car to a repair shop to replace the parts to avoid accidents.

Is Wheel Alignment Necessary After Tire Repair?

Wheel alignment is not required after tire repair, but wheel balancing is necessary. The functions of wheel balancing for car tires are: 1. Enhancing driving comfort; 2. Extending tire service life; 3. Ensuring straight-line stability of the vehicle; 4. Reducing wear on chassis suspension components. The consequences of improper wheel balancing include: 1. Regular bouncing of tires during driving, causing steering wheel vibration; 2. Vehicle resonance occurring within certain speed ranges; 3. Uneven tire wear, affecting tire lifespan and driving safety; 4. Potential damage to suspension and bearings.

How to Use Brake Fluid?

Brake fluid usage method is: For different types of brake fluid, they cannot be mixed together, as this will reduce the braking effect of the car. Do not mix gasoline, diesel, or engine oil into the brake fluid. Car brake fluid is the liquid used in hydraulic brake systems, which must not cause chemical reactions, be unaffected by high temperatures, and not cause corrosion, softening, or expansion to metals and rubber. The volume of brake fluid changes with temperature, so the brake fluid reservoir is equipped with a vent hole. The air drawn in through this hole contains moisture or impurities, and the moisture will be absorbed or dissolved by the brake fluid. Therefore, brake fluid containing moisture will have a lower boiling point.

What Does Gross Vehicle Mass Refer To?

Gross vehicle mass refers to the total mass of a vehicle when fully loaded with cargo or passengers as per regulations. The method for determining gross vehicle mass is as follows: 1. Passenger cars: Gross vehicle mass equals curb weight plus the weight of the driver and passengers plus luggage weight; 2. Buses: Gross vehicle mass equals curb weight plus the weight of the driver and passengers plus luggage weight plus accessory weight; 3. Trucks: Gross vehicle mass equals curb weight plus the weight of the driver and assistant plus luggage weight. Vehicles also have curb weight, which refers to the total mass of a vehicle with a full tank of gasoline and all fluids filled.

Why Does the Exhaust Pipe of a New Car Rust?

After being subjected to high-temperature baking, the exhaust pipe of a new car is prone to oxidation and rust. Here are specific maintenance methods for the exhaust pipe: 1. Waterproof: When driving in the rain or going to a car wash, be careful to prevent water from entering the muffler, which can cause rust and affect the exhaust pipe's performance. 2. Rust prevention: Remove the muffler, block the drain hole, add rust-proof oil, and ensure it spreads evenly inside the cylinder before reinstalling the muffler. 3. Cleaning: The exhaust pipe is often exposed to the outside, similar to the car's interior. Accumulated dirt inside can affect normal usage, so it's important to clean the exhaust pipe regularly.

What is a Coilover Suspension?

Coilover suspension refers to height-adjustable shock absorbers that allow modification of the ground clearance at all four corners of a vehicle. A coilover shock absorber features threaded components on its body, enabling users to set the vehicle's preload according to personal preferences. The threads on the shock absorber are specifically designed to adjust spring stiffness, thereby configuring the preload. There are primarily two height adjustment methods for coilovers: body-only adjustment and full-length adjustment. Body-only adjustable coilovers feature a single adjustment point at the spring perch, whereas full-length adjustable coilovers offer two adjustment points: the spring perch and the lower mount adjustment ring that surrounds the shock absorber body.
