how do I replace the rear wheel studs

I am attaching the process from the manual on how to remove these studs.

However, here is a guide that will help with this:

This is clearly a different vehicle, but it will help. Just be sure not to hammer the studs out on this vehicle as you will damage the bearing.

You must press them out so please run through this info and let us know what questions you have.

If you don't have enough room with the shoes loose then you will have to remove the hub and bearing and press them out on the bench.
