Hi guys im new to the board. I came here cause it seems like i find the best answers while roaming these forums before but I have a question that i couldnt find while searching. While trying to fix up my 3.8 to where it doesnt sound like its falling apart my local shop said i had a pulley going out. I've been looking around trying to find out if I had to replace one or all...if i have to replace all are there any kits that come with udps that you guys know of. Thanks for the help in advance.
