What Causes the Sunroof to Make Noise When Driving on Bumpy Roads?

Car sunroof noise on bumpy roads can be attributed to the following reasons: 1. Insufficient body rigidity: If the vehicle lacks structural rigidity, subtle body flexing may occur on uneven roads, causing misalignment noises from windows. The sunroof may produce abnormal sounds in such cases. 2. Frequent sunroof operation: Regular use of the sunroof during daily driving wears down the lubricating grease in the tracks, eventually causing noise at the connection points between the glass and rails. 3. Poor factory assembly: If the sunroof was improperly installed during manufacturing, abnormal sounds may develop after some time of use. 4. Weather damage to seals: Prolonged exposure to rain or sunlight can accelerate aging of sunroof seals. Rubber conditioner can temporarily restore their performance.

It is highly discouraged to use strong alkaline detergents, soap powder, or shower gel for car washing, as they have strong cleaning power but also cause significant damage. Frequent use can quickly erode the glossy finish of the car's surface and accelerate the aging of rubber components, tires, windows, etc. Here is some additional information: Car washing precautions: Always purchase genuine car wash solutions from reputable manufacturers. Genuine computer car wash wax from Taiwan is highly recommended for its affordable price and noticeable effects. The main cleaning ingredients in car wash solutions are natural plant-extracted surfactants, which are also the primary components in domestic shampoos. Additionally, car wash solutions usually contain natural car wax and components that naturally eliminate static electricity from the car body.

What Causes the Abnormal Noise When Going Over Speed Bumps?

Abnormal noise when going over speed bumps is caused by the aging of the shock absorber's buffer rubber. Solution: Replace the aged shock absorber buffer rubber. Below is relevant information: 1. The connection points between the car's shock absorbers and the body are equipped with buffer rubber, which serves to enhance comfort and protect the body. If the shock absorber's buffer rubber becomes aged and hardened, it will cause abnormal noises when passing over speed bumps or uneven roads. The buffer rubber needs to be replaced. 2. Replacing the buffer rubber requires disassembling the shock absorber. When installing the shock absorber, tighten the screws in the specified sequence and always use a professional torque wrench to tighten the screws to the specified torque. After installing the shock absorber, perform a four-wheel alignment on the car to prevent issues such as deviation and uneven tire wear.

What Causes the Engine Abnormal Noise in Magotan?

Magotan engine abnormal noise mainly has the following reasons: 1. Piston slap noise: The so-called piston slap noise refers to the abnormal noise generated when the piston side knocks against the cylinder wall. Generally speaking, when the direction of the axial force on the piston top changes as the piston moves from the compression stroke to the power stroke, piston slap noise will occur. 2. Crankshaft bearing (big end) and connecting rod bearing (small end) noise: These two types of noise can be distinguished first by the sound location and frequency. Generally, the big end produces a lower-pitched sound, while the small end produces a higher-pitched sound. 3. Intake and exhaust system noise: When there is an intake manifold leak, the engine will produce noise during idle operation, and the noise will intensify as the engine speed increases.
