7Energy Suspension requires that you reuse the original outer steel sleeves in the lower-control-arm bushings. We drilled a number of holes through each rubber insert and pried the smoking remains out with a screwdriver. The upper bushings can be removed after taking the bolts and washers off the ends of each cross-shaft. Energy Suspension furnishes new sleeves for these bushings, so you can drive out the bushing and metal shell as one unit. After disassembling the A-arms, we handed the crusty parts over to a local sandblaster.
