What Causes Truck Wheel Hubs to Overheat?
1 Answers
Wheel hub overheating may be caused by excessively tight bearings, abnormal wear, or brake drum overheating. Below are the details regarding wheel hub overheating: 1. Wheel Hub Overheating: Wheel hub overheating could be due to excessively tight bearings or abnormal wear. The wheel hub (axle head) typically overheats because the bearings are either assembled too tightly or lack proper lubrication. Excessive temperature can cause the lubricating grease inside to melt and leak out, affecting braking performance. In severe cases, it may even burn out the bearings. 2. Brake Drum Overheating: Another possible cause of wheel hub overheating is brake drum overheating, which may lead to brake drag or drum scraping. The brake drum is the part measured by the thermometer. It heats up with every brake application and is the area with the highest heat generation in the entire front wheel. The temperature of the brake drum is influenced by factors such as ambient temperature, driving speed, frequency of braking, vehicle weight, and road conditions.
