Re: PS idler arm
A few years ago, you could buy the whole kit including idler arm, bushings, washers and castle-nuts. Now, some vendors are only selling the bushings.
If you had an earlier idler arm replacement from a kit, you may notice that the shaft portion is way smaller than the original, but they cast-in a couple of "gussets" at the base of the shaft to keep the shaft centered. Those gussets can wear-down and cause too much vertical slop in the idler arm movement. So if you can only get bushings now, it may not help if you had one of those aftermarket idler arms.
