Just finished replacing the CV boots on our 620i and did the lift while it was apart. Just one more nut and the knuckle falls away. Loosen two bolts, lift the shock 1" and re-tighten OR lift it out, drop a 3/4" drive, 1 3/8" socket in, replace the shock and re-tighten bolts. I'm trying the re-tighten bolts w/o the socket lift and we'll see how it goes. The grip on the shock is fairly darned tight.
