i have replaced mine twice this past week and i will have to put another one in next weekend. it took me almost 4 hours the first time and 1 1/2 hours the second time. once you know where the three bolts are and how to get the swivel and extensions in to the bottom bolt(13 mm) and to the bolt on the back of the alternator (10 mm) then it gets easier. the only thing i did to really make it easier was to pull the cv joint out of the transmission but not out of the wheel bearing so i could get to the bottom bolt easier.
