If the left and right suspension heights of the BMW 7 Series are uneven, it is necessary to check whether the car's shock absorbers are leaking air. Next, inspect the car's air pump fuse. If there are no issues with these, perform a level calibration for the vehicle. Below are detailed explanations regarding the uneven left and right suspension height in the BMW 7 Series: Methods to determine if the shock absorber has issues and solutions: Check if the shock absorber is heating up. If it is not sufficiently hot, it indicates there is no internal resistance in the shock absorber, and the shock absorber is not functioning. In this case, add an appropriate amount of lubricating oil and test again. If the outer shell becomes hot, it means the shock absorber is low on oil internally and should be refilled; otherwise, the shock absorber is faulty. Listen for any abnormal noises from the shock absorber; check if the shock absorber is leaking oil. During normal operation, the shock absorber relies on its internal hydraulic oil. Once oil leakage occurs: the performance of the shock absorber will inevitably decline. Methods to determine issues with the air pump fuse and solutions: Under normal circumstances, the fuse serves to connect the circuit; under abnormal (overload) conditions, the fuse acts as a safety protection component in the circuit, safely cutting off and protecting the circuit by melting itself. If it is not sufficiently hot, it indicates there is no internal resistance in the shock absorber, and the shock absorber is not functioning. In this case, add an appropriate amount of lubricating oil and test again. If the outer shell becomes hot, it means the shock absorber is low on oil internally and should be refilled.

What Causes the Rear Wheel of a Motorcycle to Become Extremely Hot?

The reasons for the rear wheel of a motorcycle becoming extremely hot include prolonged braking, riding with the brake engaged, bearing damage, and insufficient tire pressure. Below are detailed explanations and solutions: Prolonged Braking: Whether the rear wheel's braking system is drum or disc, prolonged braking will cause the rear wheel to overheat, especially in drum brake systems, where the likelihood of this phenomenon is higher due to generally poorer heat dissipation. Riding with the Brake Engaged: Riding with the brake engaged is equivalent to riding while keeping the brake pedal pressed. This condition easily leads to wheel overheating, and the primary cause of riding with the brake engaged is directly related to brake system malfunctions. Bearing Damage: The rear wheel's ability to rotate smoothly mainly depends on the bearings inside the hub. However, if the bearings lack lubrication, the operational resistance increases, leading to damage, which in turn causes the hub's temperature to rise excessively. Insufficient Tire Pressure: When the tire pressure is too low, the tire's deformation during operation becomes excessive, resulting in overheating or excessive heat buildup.
