The original bushing is very pliable and is only rubber--no sleeve permanently attached. The outer sleeve is what the control arm and u-clamp directly touch. To remove the assembly you loosen the nuts (9/16" wrench/socket) on the u-clamps and the nuts (been too long to recall-11/16 or 3/4") at the end of the crosshaft. I work one end at a time with a jack under the lower control arm lifting just a little--this will allow the control arm to lift free of the outer sleeve after the u-clamp is removed. With the end nut/washer removed the bushing will slide to the end and off the shaft. Sometimes it takes some gentle persuasion to get it moving. With the combo old bushing/outer sleeve in hand you can usee your fingers or a tool to push the old bushing out of the sleeve--it is usually heavily worn--may just fall out on its own. A little lube (your choice) applied to the new bushing and it will squeeze into the old outer sleeve. Clean the end of the shaft-slip the new bushing/sleeve onto the shaft-lower the control arm end onto the outer sleeve and install the u-clamp and then the end nut/washer--leave tightening the end nut till the car is on the ground and the suspension settled.-- Dave
