[QUOTE="Deezel, post: 1240937, member: 16800"] The main advantage of the RCVs over just disengaging vacuum would be strength. There is A LOT more shear area on the RCV splines when compared to the stock IWE hub and I would be willing to bet the material is much stronger (nearly everything they make is out of 300M lol.) The downside to this, and this is just a theory is that if this is no longer the weakest part of the assembly, what fails next? I believe part of the theory with the IWE was to fuse the front driveline and save the other more expensive pieces of hardware in the driveling. Also, that silly plastic piece is no longer there to fail (which is probably the root cause of the stock IWE failures in the first place).. Even if your splines are good on the IWE, when the plastic piece breaks the stock hub splines can float back and forth. This is why you hear the intermittent grinding and popping. I've had the RCV kit on for ~60k miles now with no issues. Oddly, I haven't even noticed a hit to my gas mileage. [/QUOTE]
