The first picture shows the washer electro blasted into place. I used 4 tacks and let it cool. I went on the the next mount, tacked it, and let it cool. I was able to weld the entire front mount but, only able to weld about half of the rear mount washers due to space limitations. I only did a little at a time. I wanted to keep the mount as cool as possible.
The next picture shows the completed weld. Just remember with enough grinding anybody can be a great welder. It may not be pretty but, I know there is good penetration and that's what counts.
The last picture shows the A arm bolts. The original and last year's version was black oxide. The ones I just bought are now shiny. To recap I used Polaris RZR bushings in the top and bottom arms, new bolts, new spacers, and new nuts. The ball joints were good.
Final thoughts: After 2000 miles I can't complain about having to fix this. It happens on Polaris, CFmoto, Can Am and, every other brand. I always felt like I kept up on greasing these bushings. I don't think it matters. Some spacers came out looking like new and others were pitted and rusted. Same story with the bushings. One lower arm bolt had to be cut out because it was seized to the spacer. The other side was bent. Surprisingly the upper arm bushings, spacers and bolts were in good condition. I wonder if the lowers fail because they are exposed to more water and mud? That's enough of my rambling for now.
