:newbie: um.. what exactly is an HP 30? Obviously its a Dana 30 front axle and it came on the cherokee. What makes it "HP" and what does that stand for? High Perforance? I'm sure I read about this somehwere but I shattered the UCA mounts on my Dana 35 today. That sucked. I want to do an axle swap in the front ASAP and get rid of all of the CV hoints that I have..... ya know what I mean? Thanks guys :smiley22:
