wheel hub seal. This noise is caused by the lack of lubrication in the wheel hub, which can lead to metal-on-metal contact and damage.
One significant advantage of extension springs with loop ends is their ease of installation. The loops allow for simple connections to be made without the need for additional components. This can save time in assembly processes and reduce overall manufacturing costs. Additionally, loop ends provide security during operation by preventing the spring from inadvertently detaching from its load, which can be particularly important in high-stress environments.
