My rear subframe is coming out so I can easily install my KAAZ LSD and chromoly axles. I also have a set of RE toe links and trailing arms that Im putting in, and I am going to order new pillowball bushings as I know these need replaced also. While its out is there anything else that should be replaced? Do the upper control arm bushings go bad, or anything else Im overlooking? If so, could anyone point me to a place that sells stiffer aftermarket replacements? Thanks
