I just completed replacing the 2 inner CV joints, rear wheel bearings, ebrake shoes, coffin bar, track bar, rear lower suspension bar, shocks, springs, swaybar bushings, drop links, just about anything that moves in the rear suspension. I did not remove the bearing carrier from the car, I did not remove cats. I did remove the diagonal braces and skid plate. I found a YouTube video posted for removing the rear shock assembly. you remove the bold holding the coffin bar to the chassis along with the bolt holding the lower rear bar. These bolts have the adjusting cam for alignment. Also removed the big nut at the end of the axle holding the hub on. When you remove the 6 bolts holding the inner cv joint to the trans the whole assemble swings out and you can remove the axle. Here is the link to the video.
