once top bolt are removed use breaker bar and proper size socket to break loose the bottom bolt and nut
also soak the top and bottom bolts and nuts in pb blaseter or whatever you perfer use an impact and proper size socket to loosen the bolt until the nut comes off i used pb blaster to clean both bolts and nuts on each side
once the bolt is out of the shock top and bottom remove teh shock you may need to pry up on the bottom of the shock to remove it from the mount same as top once removed place the new shock(s) and place bolt thru the wholes in the mounts then hand tighten the nuts on the bolt(s) you may need to use a jack to compress the shock place jack on lower a arm and jack until the wholes line up once they line up place bolt thru and hand tighten nut then proceed to tighten bolts remove the jack from the a arm once done
