Your Porsche is perhaps the ultimate embodiment of elegance you’ve ever come across. But as much as it exudes confidence, luxury, class and everything in between, it still needs care. How else will it last and perfume as it should? Take its wheel bearings and hub assemblies. They are vital as far as performance is concerned. But how long in the first place should these components last? Read on to learn more.
The Hub Assembly
Located between the drive axle and the brake discs, the Porsche hub assembly is mounted to the chassis’ holding bracket on the axle side. The disc is then connected to the bug assembly through bolts. Note that the wheel bearing itself is located inside the hub unit. What makes these maintenance parts unique is the fact that they take on the load of your Porsche whether it is standing still or in motion. They become even more important as you drive over rough patches where potholes are hard to avoid.
Hub Assembly Maintenance
To ensure your Porsche assembly serves its purpose and lasts for long, minimize the amount of friction that the wheel bearing generates. This can be easily accomplished by use of quality grease specially made for withstanding high temperatures. Be keen not to overdo the amount of grease you apply. Too much grease and overheating will become imminent because of friction that cannot be dissipated appropriately.
Remember that even though regular application of grease will help hub assembly parts and components last longer, they will eventually need to be replaced. Typically, you should inspect and service your wheel bearings after every 20,000 to 35,000 miles. An average sealed Porsche wheel bearing lasts between 80,000 to 100,000 miles. Some can last to as much as 150,000 miles.
They make it easy for you to drive by reducing friction. This means they also wear at some point. Fortunately, maintaining Porsche wheel bearings is easy. Like it is the case with the aforementioned wheel hub assembly, make it a routine to inspect the wheel bearings. This should be easy if you take your car for servicing on a regular basis.
Beware of cheap, substandard and counterfeit bearings made of low quality steel complete with poor heat treating. They tend to not just fail prematurely but also extend damage to other parts. Like any Porsche expert will tell you, bearings should only be replaced once or twice during typical Porsche ownership.
Point To Note
Substandard hub assemblies often include bearings that are smaller in size than OEM hub assemblies. This is another key factor that can easily lead to early part failure. There is also the fact that cheap parts usually have double ball bearings rather than just one strong bearing. Avoid such alternatives as you can by buying from approved Porsche OEM outlets. On the same note, make sure you preferred mechanic or automotive technician is licensed. Then instead of reusing axle nuts, simply replace them. Remember to always use a torque wrench instead of an impact wrench when installing the bearings on your own.
