How to Deal with Overheated Rear Wheel Hubs?
3 Answers
Rotate the inspected wheel several times by hand to check if the rotation is smooth and if there are any abnormal noises. If the rotation is not smooth and there is a friction sound, the wheel hub should be disassembled for inspection. Inspection of the braking system. Usually, when inspecting the wheel hub bearings, the wheel braking device should also be checked, as it may be caused by leakage from the brake wheel cylinder or brake oil pipe. If the wheel hub overheating is due to frequent braking, simply reduce the use of brakes during driving.
I've been driving for thirty years, and overheated rear wheel hubs are a common issue, usually caused by brake pads sticking or bearing wear. If you notice severe overheating, immediately pull over to a safe spot and stop driving, as it could lead to fires or wheel detachment. Let it cool naturally—don’t pour water on it to avoid warping. After cooling, do a quick check: see if the brake caliper moves smoothly and if tire pressure is normal. If you can handle it, try adjusting the brakes; otherwise, don’t risk it—call a tow truck to a professional repair shop. Ignoring this can damage the hub long-term, hike repair costs, or even cause accidents on highways. I learned the hard way when a hub overheated and ruined my engine in my younger days. Prevention is key: regularly inspect brakes and bearings, monitor hub temps in summer heat, and a quick pre-drive check can save major headaches.
As an ordinary car owner, if you notice the rear wheel hub getting hot, stop driving immediately. Possible causes include improperly released brakes or a damaged bearing. Find an open area to park and let it cool for half an hour. During this time, check for any tire leaks and whether the brake pedal feels normal. If it's excessively hot, don't attempt to dismantle it yourself—instead, use your phone to search for nearby repair shops and call a professional. Mishandling can lead to wheel damage or accidents, so don't hesitate to pay for towing services. To reduce the likelihood of this happening, avoid overloading or sudden braking in daily use. Make it a habit to check for unusual noises or heat from the wheel hubs during car washes—good habits prevent problems.
