How to Determine if a Wheel Hub is Out of Round?
2 Answers
To determine if a wheel hub is out of round, you need to visit a 4S shop and have it inspected with professional equipment. An out-of-round wheel hub can have the following effects on a car: 1. A severely out-of-round wheel hub can wear out bearings and half-shafts. Over time, the seal between the tire and the wheel hub may develop issues, leading to tire leaks and reduced tire pressure. 2. An out-of-round wheel hub can also affect the chassis suspension. In mild cases, it may cause slight deformation, while in severe cases, it could lead to the breakage of suspension adjustment arms. How to Handle an Out-of-Round Wheel Hub: Most car wheel hubs today are made of aluminum alloy. Once a wheel hub becomes out of round, it is extremely difficult to repair. Even if repaired, the wheel hub will not return to its optimal factory condition. For safety reasons, it is recommended to replace it directly.
After driving for a long time, I've summarized a few ways to identify wheel rim deformation. If the steering wheel noticeably vibrates when driving at speeds between 60 to 80 km/h, that's a typical sign of an out-of-round condition. After parking, first visually inspect the wheel rim surface for any dents or protruding damage, especially near the tire edge. If you have tools, lift the car with a jack, slowly rotate the wheel, and observe whether it rolls smoothly without wobbling—an uneven rotation will show obvious shaking. Don’t ignore these signs, as deformation can lead to uneven tire wear, increased fuel consumption, and even loss of control at high speeds. I usually avoid curbs when parking to prevent impacts that could cause deformation. It’s also good to keep a simple straightedge handy to measure the gap between the wheel rim edges for consistency. If you're unsure, promptly visit a repair shop for a professional balance machine test for peace of mind. This not only improves driving comfort but also ensures road safety.
