Well, that's a good question. I haven't done anything yet, but I've thought about adding shims, or finding suitable replacement bushings, and just peening over the end of the post at the joint. I may go that route, especially when I find out how much the linkage assembly is going to cost.

Keep in mind that accessing the wiper assembly is a bit of a production, requiring the removal of lots of brittle plastic pieces for the air intake screen and windshield drip rail. I'd prefer to do this just once if could.

I'll post a follow-up when I find out a part number and cost for the linkage assembly. Since this job is such a chore, it makes sense for someone heeding my advice to pre-order the assembly and do the R&R all at once. If I end up rebuilding the unit, I'll post some pics of the final results.
