To prevent bearing problems from re-using the axle nut, I replaced the rear wheel bearings and seals, AND the axle nuts. Hopefully, that will be enough.
While the cradle is out, small issues with insulation were addressed, along with a few rust spots. The rust on the strut hats has also been addressed.
The broken plug wire retainter clip was replaced, and the plug wires are now routed correctly and the correct length.
