Wheel bearing is a vital component of your BMW as it serves a dual purpose on the efficiency and performance level of the vehicle. It acts as one of the suspension components that help in supporting the massive weight of the vehicle and carrying the added load of the passengers and cargos. The wheel bearing basically allows the wheel to move with minimal friction occurring in order to eliminate heat production. Without wheel bearings, the wheel of your BMW vehicle will prematurely wear out because of friction, leaving you costly replacements. Nonetheless, constant lubrication is needed is the only thing that's needed in order to avoid any mishap with regards to your BMW wheel bearing. There are two types of wheel bearings that can be used on your BMW namely the open wheel bearing and the sealed wheel bearing. The open type of wheel bearing needs to be inspected regularly as this is susceptible to damages as lubrication may leak and accumulation dirt that can adversely affect the performance and function of the bearing. The sealed type of wheel bearing on the other hand, which is sometimes called as lubricated for life type of wheel bearing, has got the more reliable engineering. This is called as such, because it's already heavily lubricated before leaving the factory. To prevent its lubricant to leak out, a rubber sealing is used on both sides. This is considered as one of the most cost effective wheel bearing that is commonly used today. Nevertheless, wheel bearing tends to wear and its function becomes less reliable, even with the sealed type. Replacement would be needed after two years or 24,000 miles, depending on the application of the vehicle.
