Thank you so much for the help bigtonka... this stuff has been keeping me up at night

is this centre hanger bearing something that carquest or NAPA would supply? or do I need to do some junk yard diving to find the healthiest replacement?
I've never used a grease gun before, but I'm assuming you just pump the nipple full of grease till it excretes somewhere? I noticed the one on the MC and wasn't sure how much grease to pump in there.
