The rubber covering (or “boot”) around a CV joint in a driveshaft does a very important job. Not only does it keep the joint inside clean and protected from road dirt and moisture, but it helps keep the sticky grease used for lubrication in.

Your steering rack is important. Not only does it help you aim your car where you want it to go, but it ensures it continues to go in that direction at all times.

As well as their legendary handling (hang on, that was meant in jest!), Sierra's are also known for their appetite for warping front brake discs.
