What Causes the Abnormal Noise When Magotan is Driving at Low Speed?
3 Answers
Here are the specific reasons for the abnormal noise when Magotan is driving at low speed: 1. Gear damage: It may be caused by broken gear teeth or surface damage on the drive wheel. If the gear is damaged, it should be replaced promptly. 2. Loose wheel components: The noise may be caused by loose connecting parts of the wheel. There are many gears in the wheel transmission system, and if they are loose, they will make noise when turning. 3. Cold start: The components are cold and hard, and the lubrication is insufficient, leading to abnormal noise. Additionally, when the drive wheel slips, avoid sudden acceleration to prevent the planetary gears from locking on their shafts. 4. Break-in period: If the car is in the break-in period, the differential planetary gears and axle gears may not match properly, resulting in abnormal noise.
I've been driving my Magotan for several years, and there's been abnormal noise at low speeds, such as squeaking when turning or going over speed bumps, which is probably related to the suspension system—possibly due to aging bushings or loose shock absorber components. The braking system also has issues at low speeds, with brake pads wearing against the discs and producing squeaking sounds, especially more noticeable on rainy days. If small stones get stuck in the tires or there's uneven wear, strange noises can also occur while rolling. It's important to regularly check these areas. I recommend first going to a 4S shop to lift the car and inspect the suspension arms or tie rod ball joints. Replacing the bushings and tightening the screws can make things quieter—don’t wait until the noise gets worse, as repairs will be more expensive. These parts naturally wear out over time, so regular maintenance can help reduce trouble.
I feel a clicking sound under the car when driving the Magotan at low speeds during my commute. As a beginner, I'm quite uneasy. After searching online, I suspect it might be due to lack of lubrication or damage in the wheel bearings, as bearing friction noise is more noticeable at low speeds. It could also be the loose underbody shield hitting around when bumpy, or a cracked exhaust pipe hanger. Last time at the car wash, the mechanic mentioned it might be uneven brake discs or dirty pads causing the noise. I plan to test the sound changes by driving at high speeds this weekend. If that doesn't help, I'll go to a quick repair shop for a thorough check of the bearings and suspension system. It won't cost much but will give me peace of mind, avoiding potential dangers at high speeds later.
