Just did the busings to all four springs. You can either use a pair of big pliers, or vise grips that look like they fit around a soda can ( I bought a pair at HomeDepot). The bushings are two piece, with an inner sleeve. This didn't work on all bushings. If if doesn't, place the spring pack in a table vise, take a drill with 1/4" bit and start drilling through the bushing. This may take a while, but it works. Once you get most of the bushing drilled out, take a metal shank to the lip of the bushing sleeve and bang out with a BFH.
The plier/vise grips work if using on poly bushings. The drill method works on OEM rubber bushings. Note, if OEM rubber bushing, there is also an outer metal sleeve that either needs to be cut with a Saw-zall or pryed out with a chisel. I used a small diameter chisel (1" in width), aslo bought at HomeDepot, and hammered out. This will take some time, as you need to split the outer sleeve. Pretty straight forward. This was my first time doing this and although took some time to do all the spring ends, new bushings were definately needed!
After bushings are out, use a wire brush to clean out the spring eyes. Use a bunch of grease and new bushings should slide in. You may need the table vise the press bushings in completely
