How to Repair a Deformed Car Wheel Hub?
2 Answers
Here are the methods to repair a deformed car wheel hub: 1. If the car wheel hub is only slightly deformed, you can apply touch-up paint, remove dirt, and then attach a filler tape to the deformed area for correction. 2. If the wheel hub is severely deformed, it should be replaced with a new one as soon as possible. Deformation caused by impact, even after repair, may lead to wheel wobbling, significantly affecting driving safety and vehicle performance. Below are the main causes of wheel hub deformation: 1. Collision between the tire or wheel hub and hard objects: When a vehicle passes over hard objects such as curbs, protruding manhole covers, speed bumps, or road potholes at high speed, it can easily cause wheel hub deformation. 2. During driving, if the tire cannot fully absorb the impact force, part of the force will reach the wheel hub, leading to deformation. 3. When the tire is flat or the tire pressure is extremely low, continuing to drive long distances will cause the vehicle's weight to act directly on the wheel hub. Without any cushioning between the wheel hub and the ground, deformation will occur.
When I discover a wheel rim is deformed, as a technician who repairs cars daily, I recommend first assessing the extent of the deformation. Slight bends caused by minor impacts can often be corrected back to their original shape using a rim straightening machine through cold pressing, applying pressure gradually to avoid cracks. After repair, a dynamic balance test is essential to ensure smooth tire rotation; otherwise, you may experience steering wheel vibrations while driving. In cases of severe deformation, such as large dents or cracks, avoid forcing a repair—replacing the rim entirely is safer. I always remind customers that wheel rim issues can affect the entire suspension system. Neglecting them can increase fuel consumption and even risk loss of control at high speeds, so never take it lightly. Slowing down when driving over potholes daily can prevent most deformation issues.
