The reason for the squeaking sound when the Baojun 730 drives on bumpy roads is due to damaged buffer rubber in the chassis or loose ball joints in the chassis bracket. It is recommended to go to a maintenance station for inspection and repair. Taking the 2021 Baojun 730 1.5T manual fashion 7-seater as an example, this car is equipped with a 1.5T turbocharged engine and a 6-speed manual transmission, with a maximum power of 108kw, a maximum torque of 250nm, a maximum horsepower of 147ps, and a top speed of 170km/h. In terms of suspension, the front suspension type of this car is MacPherson independent suspension, the rear suspension type is torsion beam non-independent suspension, the body structure is unibody, and the power steering type is electric power.

I've been driving for many years, and squeaking noises from the Baojun 730 on bumpy roads are quite common—it's likely a suspension system issue. The rubber bushings on the suspension arms or shock absorbers may have aged or worn out, causing parts to rub and squeak when going over potholes. Loose chassis bolts could also be the culprit, especially in older cars where rust has weakened the connections. Overinflated or unevenly worn tires can also trigger such noises, so check if the tire pressure is correct. Don’t overlook small details like worn or loose brake pads, which can squeak when driving over bumps. Find time to get it checked soon to prevent further suspension damage and costly repairs. It’s best to take it to a repair shop and have the car lifted for inspection. If you’re doing it yourself, start by checking the tires and suspension for tightness.

How to Remove a Stuck Volkswagen Ignition Lock?

The steps to remove a stuck Volkswagen ignition lock are: 1. Insert the key into the keyhole and rotate it 90 degrees clockwise; 2. There is a small hole next to the keyhole, insert a prepared steel wire into it; 3. The ignition lock cylinder will pop out, allowing you to remove it.

What is the duration of the three-guarantee period for vehicles?

The three-guarantee period for vehicles is no less than two years or 50,000 kilometers, whichever comes first. During the "three-guarantee validity period," if the conditions for return or exchange as stipulated are met, consumers can process return or exchange procedures with the "three-guarantee" certificate, purchase invoice, etc. If the cumulative repair time due to product quality issues exceeds 35 days, or if the same product quality issue has been repaired more than five times cumulatively, the consumer can request a vehicle exchange with the three-guarantee certificate and purchase invoice. The "three-guarantee" regulations also stipulate that consumers can choose to replace or return the vehicle product under the following circumstances: 1. If two repairs have been conducted cumulatively due to severe safety performance failures, and the severe safety performance failures have not been resolved or new severe safety performance failures have occurred; 2. If the same major component of the steering system, braking system, suspension system, front and rear axles, or body has been replaced twice due to quality issues and still cannot function normally. The seller shall be responsible if the consumer chooses to replace or return the vehicle.

Can You Step on the Accelerator During a Hill Start?

You can step on the accelerator during a hill start to prevent the car from stalling or rolling backward, as it provides additional power for climbing the slope. If you are not proficient in operating the clutch and cannot rely solely on it for starting, pressing the accelerator during a hill start serves as a precaution. Additionally, when starting on a slope, avoid releasing the clutch pedal immediately. Instead, first engage the accelerator and then gradually release the clutch, as the car encounters greater resistance on an incline and requires more power to start. The key point is the timing of releasing the handbrake. During the start, press the accelerator with the ball of your right foot while slowly releasing the brake with your right heel, and gently lift the clutch with your left foot. After starting, fully release the clutch pedal. The coordination between the ball and heel of your right foot is crucial. This hill-start method is relatively difficult to master and is recommended only as an emergency measure.

Why is the exhaust pipe particularly black after high-speed driving?

The reasons for the exhaust pipe being particularly black after high-speed driving are: 1. Poor engine combustion; 2. The engine's fuel system has not been cleaned for a long time; 3. Poor quality gasoline. The exhaust pipe is part of the engine's exhaust system, which mainly includes the exhaust manifold, exhaust pipe, and muffler. Generally, the three-way catalytic converter, which controls engine pollutant emissions, is also installed in the exhaust system. The exhaust pipe usually includes the front exhaust pipe and the rear exhaust pipe. The main functions of the exhaust pipe are exhaust and noise reduction. The composition of the entire exhaust system is: exhaust manifold, three-way catalytic converter, intermediate muffler, tail muffler, and connecting pipes.

Why does the car still roll when in P gear?

The reason the car still rolls when in P gear is that the vehicle is parked on a slope, which can cause rolling. P gear is a common gear position in automatic transmission vehicles, usually located at the foremost position on the gear shift console, in front of the R gear, designed to lock the axle when the car is stationary on a slope. After shifting into P gear, the handbrake should be firmly engaged; otherwise, it may cause excessive force on the P gear locking mechanism, reducing its service life. The correct method is to shift into N gear first, engage the handbrake, and then shift into P gear. This approach can extend the service life of both the transmission and the P gear locking mechanism.

How to Deal with White Marks on Car Paint Caused by Firecrackers?

To address white marks on car paint caused by firecrackers, use a damp cloth with a bit of dish soap to gently wipe the affected area. If wiping doesn't remove the marks, the only solution is to polish and wax the car paint again. Avoid using a dry cloth directly, as residue from the firecrackers can cause further damage to the paint by scratching it back and forth. Note that car paint can only be polished a limited number of times; frequent polishing can cause permanent damage to the paint. Car paint is a type of coating sprayed onto the vehicle, forming a protective film on the surface. This not only prevents corrosion but also extends the car's lifespan.
