So...here goes. I have an 06 MO with 72K miles. Wife was driving the other day and said she thought something "fell out" of the passenger side. Immediately after the battery and brake light came on on the dash cluster. I said I would look at it the next day. The next day came and when I got up, they were at the hot springs. Got a call a short time later from her saying it "wouldn't go." I went and picked her and the kids up and found it would idle and rev in neutral, but in drive or reverse wouldn't go. A little research told me it was something with the alternator. Picked up an alternator and began digging in. Half way into removing stuff for alternator access, I noticed no belt on the alternator...change in direction. Accessed the alternator area and found the belt (in good condition) sitting there. Found the idler pulley was no longer there! Bracket is good but missing a few pieces. I picked up a new pulley, but am concerned with spacing behind the pulley so it doesn't "drag" or "rub" on the bolt heads behind. Anyone know the thickness and diameter of the spacer behind the pulley?
