What Causes the Right Rear Wheel of a Car Not to Turn?
2 Answers
For front-wheel-drive vehicles, the reasons for a rear wheel not turning include: 1. The brake caliper not retracting or a blocked hydraulic line. 2. The brake pads not separating or foreign objects embedded behind the brake pads. 3. A seized wheel hub bearing. For rear-wheel-drive vehicles, the reasons for a rear wheel not turning involve not only checking the braking system but also inspecting the rear axle's main reducer and differential planetary gears. Below is relevant information about car tires: 1. Replace tires when tread depth is below 1.6mm: According to national standards, the wear limit for tread depth on passenger car radial tires is 1.6mm. On the sidewall of the tire, there is a wear indicator signal mark every 30 degrees. You can compare it with a key you carry. If the groove depth is below 1.6mm, the tire should be replaced. 2. Neither underinflation nor overinflation is advisable: Incorrect tire pressure can lead to cost losses and hazards. Underinflation reduces the tire's durability, increases rolling resistance, and lowers fuel economy. Overinflation decreases traction performance, causes irregular wear, especially on the drive axle.
I've encountered the issue of the right rear wheel not turning several times. With years of driving experience, I know it can be caused by various reasons. The most common is a stuck brake system, such as faulty brake pads or a caliper, which locks the wheel completely. It could also be due to worn rear wheel bearings, making rotation extremely difficult. For rear-wheel-drive vehicles, problems with the differential or drive shaft can also affect wheel rotation. Additionally, a flat tire or rusted wheel hub might jam the wheel. First, check around the wheel for any foreign objects blocking it, then try pushing the car to see if it moves. If the problem persists, don't force it to drive—it's very dangerous. Regular car washing to prevent rust can help reduce such failures.
