Hey Friend, I was being a little nosey and I noticed something on that picture of that NEW throw out bearing you displayed. It looks like that throw out bearing has a "Plastic Seal" on it. I find these to be okay but only for the short term. The reason why is because I had to replace my OEM throw out bearing on my 1990 Nissan Hardbody, with a clutch kit that included the
Flywheel, Clutch, Pressure Plate, Pilot bearing and throw out bearing, which came completely assembled on the throw out bearing hub. Two (2) years and 7,000 Miles later I had to replace the transmission,... and in the "Haynes" Manual, it specified that if the "Throw Out Bearing" is making any noise when you spin it by hand it needs to be replaced, and that's exactly what mine was doing, just after that short period of time. After closely inspecting the throw out Bearing I noticed that some grease had seeped it's way out of the bearing because of that "Plastic Seal" . I purchased a
"KOYO" Japanese

throw out bearing on
E Bay. This "Bearing" came completely sealed with no seams for grease to escape either.
