So I am installing my MM CC plates and the upper passenger bearing came apart. I did not lose any of the ball bearings and it looked clean, but when I snapped it back together I could feel some grit. I have Mobil1 synthetic grease (the pinkish one). Would that be acceptable to use after a thorough cleaning? I can't tell if the oem stuff was white lithium grease or not, it is all brown. The bearing housing appears to be Nylon.
