I will give it a shot. I rotated my tires last weekend and saw grease splattered all over the wheel well. I regreased the transmission of the CV joint side over a year ago. Looks like the other end ( wheel hub side ? ) spilled its guts. I just noticed a whirring sound on smooth roads on sunday that seems to be from that side now ( so thats why im thinking of replacement. I dont know how long I have been driving with no grease LOL....no clicking on turns though.
