What Causes Interior Noises on Bumpy Roads?

When encountering rattling noises on bumpy roads, it can be challenging to pinpoint the exact cause due to the numerous components and complex structure of a vehicle (such as loose parts). If the specific source of the noise cannot be identified, it is recommended to have the vehicle inspected at an authorized dealership to ensure safety. Below is an introduction to common causes of interior noises on uneven surfaces: 1. Lower Control Arm Issue: The lower control arm supports the tire and features two rubber bushings and a small ball joint mounted on the steering knuckle. Prolonged driving and steering can wear down the ball joint and bushings, creating excessive gaps that cause rattling on rough roads. Replacing the control arm will resolve the noise. 2. Shock Absorber Top Mount: This component provides cushioning and shock absorption. A properly functioning top mount creates a slight upward lift after the tires fully contact the ground when crossing speed bumps or uneven roads, enhancing ride comfort for the driver.

What to Do If You Can't Find the Reference Points When Reversing into a Parking Space?

The first reference point when reversing into a parking space is the point at which you turn the steering wheel fully. When the left rearview mirror aligns with the starting line, immediately turn the steering wheel fully. The second reference point is when the car body is about to enter the parking space, and the rear of the car is close to the parking space line. Observe from the rearview mirror to ensure the wheels maintain a horizontal distance of about 30 centimeters from both sides of the parking space. Adjust if the distance is too wide or too narrow. Additional information is as follows: Reversing into a parking space: The so-called reference points are specific visual markers used during the reversing process to perform certain actions. Whether reversing to the right or left, the two most important reference points are the point at which you turn the steering wheel fully to the right (or left) when reversing and the reference point used to adjust the direction just before completing the parking. Once the car is in the parking space, observe the left rearview mirror and the edge of the parking space. When the lower edge of the left rearview mirror aligns with the edge of the parking space and you can no longer see the edge of the parking space from the left rearview mirror, press the clutch and brake, stop the car, and the reversing process is complete. When adjusting the steering wheel during reversing, there are no absolute reference points. The general principle is to steer toward the side where the car body is farther from the edge, ensuring the car is centered in the parking space and parallel to the edge lines.

How to Remove Oil Film from Car Glass?

Removing stubborn oil film can be done with readily available materials depending on the situation—toothpaste, dish soap, or oil film remover (clean the glass with water first to avoid scratching it with residual sand). Here are the details: 1. Dish soap: Every kitchen has it, but it can only remove part of the oil film and is not very thorough. After some use, the oil film will still reappear. 2. Toothpaste: Toothpaste is like a universal cleaner. Its abrasive particles and oil-repellent properties make it more effective than dish soap at removing oil film, achieving a more thorough result, though it’s not as convenient to wipe off as dish soap. 3. Oil film remover: Oil film remover works the best. Compared to toothpaste, it is more durable and affordable. If not in a hurry, using an oil film remover is recommended. Regularly applying a coating to your car glass several times is the best preventive measure.

How to Solve Wiper Blade Jumping and Abnormal Noise?

Abnormal noise caused by the wiper blade itself generally suggests replacing the wiper blade once a year. Foreign objects between the wiper blade and the windshield can cause abnormal noise; check the wiper or clean any debris beneath it. Noise from friction in the wiper arm bushing requires inspection of the wiper arm or the wiper linkage bushing. Abnormal noise from the wiper motor is best addressed by a professional repair shop for a more detailed inspection.
