I was trying to see what the other companies do. RE uses the rubber on the axle side like this, http://www.rubiconexpress.com/Products.aspx?Cn=263&Pn=1982&XnPath=173,180,251,263&Vid=AFBB6D578482
I will look for RK set up. I know BigwheelBob used those kits on my buddies XJ's so he might be able to answer that question for me. I am sure he'll post up. Just remember the rubber bushing is a lot cheaper than the RE joints so if wear is a factor I would rather the rubber wear than the joint. Just my 2 cents. Keep in mind I am just a shadetree mechanic though.
