How to Repair Damaged Vehicle Wheel Hubs?
2 Answers
Vehicle wheel hub damage can be repaired using the following methods: 1. Deformation Position Detection: First, locate the deformed area of the wheel hub. Mount the hub on a fixture and use a dial gauge to find and calibrate the deformed position. 2. Heating: Use a blowtorch to locally heat the deformed area. The small red dots on the hub are infrared thermometers; stop heating once the desired temperature is reached. 3. Correction: Once the hub softens at the appropriate temperature, use a small hydraulic jack for repeated slight corrections. 4. Completion. Note: If the reinforcement ribs of the wheel hub are severely deformed (left-right wobble), repair is not recommended.
I accidentally scraped the curb and scratched the wheel rim, so I hurried to the repair shop to fix it. The mechanic said if it's just scratches, they can first smooth it out with sandpaper and then spray on special paint, making it look like new. If the wheel rim is slightly deformed, it needs to be straightened with a machine; otherwise, you might feel steering wheel vibrations while driving, and it will consume more fuel. Repairing aluminum alloy wheel rims is relatively easy and not too expensive, costing just a few hundred yuan. However, if it's cracked or severely deformed, don't take the risk of fixing it yourself—just replace it. I was lucky this time; after the repair, they checked the balance to ensure driving safety. Usually, when driving, it's important to avoid obstacles, as protecting the wheel rims is crucial.
