The other thing I noticed when doing this bushing replacement is concerning the new steel wire circlips. If you look at the ends of the clip, one side is angled-in and one is angled-out. Looks like they cut the clip at an angle. The problem is if you are using ring pliers, the side with the angle out allows the plier pin to slip out easily. The angle-in side bites nicely. So I took the new clips and ground the one side to match the angled-in side.
Incidentally concerning the bushings, I went so far as to use a degreaser and sanded the ID of the arm where the bushings go with 80 grit sand paper. That really locked the OD of the bushings in the arm. Now both sides are perfect.
Live and learn. Seems like I mostly just learn though!
