In this video, we will discuss the benefits of using a OE quality parts. When we’re replacing a wheel bearing, the best option is to use OE quality equipment, and here are a few reasons why.
In front of me, we have three bearings. Two of which are aftermarket bearings, and one is an OE bearing. Although they may all look very similar on the outside, it does not indicate how they would perform on the vehicle. To evaluate how they might perform on a vehicle, each bearing had undergone a 0.8G overturning moment test. The OE manufacturer specs out that the 0.8G test must survive for an L 10 criteria of 30 hours. Our first aftermarket bearing had only achieved an L 10 of about 6.5 hours. The second aftermarket bearing it only achieved an L 10 of approximately 905 hours. Whereas the OE bearing achieved an L 10 life of the little over 61 hours. That is more than double the criteria in this bearing.
Once testing has completed, we have to take apart the bearing to determine what type of internal failures the bearings have experienced. For our first bearing that had L 10 of 6.5 hours, once we disassembled the part, we can see that there was intense raceway flaking damage. Our second aftermarket bearing, which had an L 10 of approximately 9.5 hours had a different type of failure. For this bearing, after disassembly, we actually noticed that it has both ball and cage failures. As for the OE sample, its test was suspended due to the fact that it had far exceeded the OE Manufacturer’s testing criteria. Upon inspection of this bearing, you see that there was no damage found to any of the race ways, balls, or cages.
Based on the bench testing and internal inspection results shown in this video, you can see why it is important to replace wheel bearings with OE quality parts. For other installation tips, training videos, and frequently asked questions, visit the BCAhub.com.
