The factory bearing is sealed and lubrication is the issue causing failure. The turbo cars and GT3 cars do NOT have this problem, they have pressure fed bearings. So obviously the design of the bearing is at fault, and can certainly be aggravated by improper oil maintenance. The replacement everybody uses is from LN Engineering, and the dealers use it too. The job is expensive, but if you are doing a RMS or clutch job, the incremental cost is not a big deal.
