The MMR spherical bearings replace the forward bushing on the rear control arms, which is the one that contains the factory toe adjustment, I believe. I was originally going to replace the bushing with one from the Energy Suspension kit but after doing some reading it is not recommended to replace that is you have adjustable camber links (MMR or AWR). This is where I first heard of the MMR bearings as most people recommend those or to stick with stock if you have the adjustable links. Here is MMR's website:

Regarding the other stuff I have a FSM and I'm familiar with Mazdatrix's walkthrough so I have a vague idea of what needs to be done. My biggest concerns right now are removing the 32mm nut as I don't have an impact wrench and pushing the axle in so I can remove the carrier/hub assembly.
