You probably don’t know this but your Porsche cannot move an inch without functional ball bearings. In simple words, they matter. That is because ball bearings are designed to promote efficient wheel rotation. They also provide the first connection between static and moving areas of your Porsche. A ball bearing, it its simplest form is a spherical friction reducing device placed within a wheel system to aid efficiency of rotation. This is achieved with the bearing because rolling produces less friction force compared to sliding.
How Ball Bearings Work
Porsche wheel ball bearings work by using small metal balls designed to roll between two smooth but strong rings of metal. Along with car grease, the bearing rotates in tandem with the wheel. The rolling motion of the balls allows the wheel hub to rotate as freely as possible. Note that the wheel bearing is housed inside the hub assembly. This makes it easy for the bearing to provide static connection with the hub carrier via an outer ring which is sometimes referred to as a racer. The driveshaft travels from the car’s transmission and passes through the center of the wheel bearing through the racer or the inner ring. This creates rotational partnership which enables the car to move with ease.
What Happens When They Fail?
Your Porsche’s safety will be significantly compromised. This should not worry you though if you take your car for schedule maintenance. It is also important to note that like nearly all mechanical parts that rotate, rub an roll, ball bearings wear out. They simply succumb to friction. This won’t you catch by surprise though because a wheel bearing that has had its day will always come along with signs. It could be a hum or constant drone from the affected wheel or traces of metal in the engine oil.
Note that the ball bearing can also be problematic because of other reasons apart from the aforementioned ones. Incorrect alignment because of poor installation can also easily mean your Porsche ball bearings will spill out. A leaking or damaged seal is just as bad. An inward collision because of a side impact can also affect the ball bearings. All these explain why it is important to have an expert troubleshoot your Porsche ball bearing issues.
What To Do When Ball Bearings Fail
The most obvious answer is of course, to have the bearings replaced. Like already explained however, this is not a Do It Yourself project. Have an expert do the fixing, repair and troubleshooting. But before then, take time to notice the tale tell signs of a failing ball bearing system. A seal leak for instance, should never be ignored. It can easily end up compromising the stability of all the four wheels.
Compromised ball bearings can also make it very hard for you to take corners. The end result is a damaged wheel system and expensive repairs. That is why regular vehicle maintenance is always advised. That is why too, you should always have a Porsche ball bearings expert on your speed dial.
