Does a Deformed Car Wheel Hub Need to Be Replaced?

It can be repaired, but replacement is recommended. First, pad the dented area with materials like sponge or cloth, then forcefully hammer the dented part flat with an iron hammer. The flattened dent will inevitably be uneven. This is not a problem as you can use body filler (putty), typically used for leveling during auto body painting, to restore the roundness of the wheel hub. After smoothing out the uneven areas, use sandpaper to roughen the inside of the wheel hub in preparation for the next step of painting. Place it in sunlight to allow the putty to dry thoroughly. The subsequent steps are similar to car painting—spray the entire wheel hub. Since the original wheel hub has the natural color of aluminum alloy, which cannot be matched by any paint, the entire hub must be sprayed. Use automotive spray paint that closely matches the original color of the wheel hub to paint the entire inside. Wait for the paint to dry. Aluminum Alloy Wheel Hub: As a metallic material, aluminum alloy behaves like a wire that can be bent back into a straight line, but after two or three attempts, it will break. This is even more critical for a large wheel hub. If the wheel hub is forcibly restored to its original shape, it may look new externally, but its internal structure will be severely weakened. Moreover, if the repaired area is impacted again during driving, the wheel hub could fracture directly, leading to a serious traffic accident.
I found that deformed wheels must be replaced because it severely impacts driving safety. When driving, a deformed wheel causes tire imbalance, leading to severe steering wheel vibration, vehicle deviation, or tire blowouts. I personally experienced this once—a slightly deformed wheel nearly caused a loss of control on the highway, but fortunately, I handled it in time. I recommend regularly checking wheel conditions; even minor deformities can lead to bigger issues. Don’t attempt repairs—once the wheel material’s strength is compromised, it’s hard to restore. Safety always comes first, so if deformation is confirmed, replace the wheel immediately at a professional shop to avoid potential accidents. The cost is worth it—far cheaper than repairs or accidents. Additionally, avoiding potholes helps reduce the risk of deformation.
I don't think deformed wheels necessarily need immediate replacement - the key factors are the severity of deformation and your budget. For very minor deformations, some repair shops can use specialized machines to correct them, costing just around a hundred yuan. I once had this done and drove without issues for over half a year. However, severely deformed wheels should be replaced immediately - otherwise you'll experience earthquake-level vibrations while driving, which could shorten tire lifespan or even cause blowouts. You can start with a wheel balance test - if significant deviation is found, don't hesitate to replace them. Budget considerations are understandable, but don't compromise safety to save money. Aftermarket wheel replacements costing a few hundred yuan are still cheaper than accident expenses. Overall, balancing safety and cost is crucial - it's best to consult a technician before deciding.
I've driven over a dozen cars, and wheel rim deformation is a common issue. Minor deformations might be repairable, but in most cases, it's better to replace the rim. Otherwise, you'll experience noticeable vibrations and instability while driving, especially at high speeds, which can be dangerous. I've dealt with this several times, and replacing them proved more reliable. Repairs have limitations—once a rim is deformed, its strength decreases, making it prone to recurring issues. For safety, I recommend checking and replacing it directly. Addressing it early saves time and effort.
