Why Do Car Front Wheels Get Hot?

[AndresAnn]

There are two possible reasons for the overheating: one is the wheel hub (axle head), and the other is the brake drum heating up. 1. Wheel hub (axle head) overheating: This may be caused by excessively tight bearings or abnormal wear. Overheating of the wheel hub (axle head) is generally due to overly tight bearing assembly or poor lubrication. Excessive temperature can cause the grease inside to melt and leak out, affecting braking performance, and in severe cases, it may burn out the bearings. If the wheel hub bearing malfunctions, it may cause noise, bearing overheating, and other phenomena, especially more noticeable in the front wheels, potentially leading to dangerous situations such as loss of steering control. Therefore, wheel hub bearings must be maintained regularly. 2. Brake drum overheating: This may be due to brakes not releasing properly or rubbing against the drum. Whenever you apply the brakes, they generate heat. If the brake drum is overheating, you can jack up the front wheel and rotate the tire to check if it rubs.
