Car wheel hubs can indeed be repaired, with specific methods determined by the extent of damage. For minor scratches or scuffs, wet sanding with 2000-grit sandpaper followed by polishing and application of specialized clear coat is sufficient, costing approximately 50 to 200 Malaysian Ringgit and taking 30 to 60 minutes. For gaps or localized deformations on the hub edge, professional repair using hydraulic cold pressing technology is required, along with dynamic balancing (imbalance must be less than 5 grams), costing about 300 to 800 Malaysian Ringgit. Severe damage-such as cracks exceeding 3 cm in length or deformation surpassing 3% of the hub diameter (e.g., over 16 mm for an 18-inch hub)-necessitates replacement. Factory-certified hubs typically cost between 800 and 3000 Malaysian Ringgit. Post-repair, a water immersion test must confirm airtightness, aggressive driving should be avoided for the first 100 kilometres, and tyre pressure should be monitored daily for a week. All repairs must be performed by qualified technicians using professional equipment to ensure driving safety and hub performance.
