OK, I wouldn't know how to check from the outside looking in...and don't know the difference between the new and old parts...so how do ya do that? Sorry, it's been a long time since I worked on any vehicle, owned a drove a jeep wrangler, never really worked on it.

Do you need to pull off the front cover for this inspection, any "window plate"...

The seller was a young mechnic and had done work on it...I will check his list of fixes, but don't think the pulley was on there...

Is thereany special oil/lubs for these vehicles, or will any jiffy lube place get it right? Thanks guys!
