Got the parts for the recall and put them in yesterday. For my 360 it's a whole new cast aluminum knuckle for both sides and new A-Arms. The A-arm attaches to the knuckle via a castelated (Sp?) nut, very much like a ball joint on a front end. The only thing that I found was that the quality of one of the nuts was not great and I had to thread chase and run a tap through a different nut that I used. I also had to use two washers on top of the nut to make the nut index well to the cotter pin hole.
Not a really big job, just lots of cotter-pins to fiddle with and lots of different torque specs on reassembly. The pieces that I took off had absolutely Zero play and no evidence of any problem, but the new pieces are not fastened the same as the original. I used stud & bearing grade Loc-Tite and doubt that it will ever move. This is tried and tested in a zillion cars and trucks.
Have a good day.
