Replaced the fronts on my 560sl in a couple of hours. Did not disconnect anything. The only bolts I touched other than removing the wheel were the mount bolts themselves. You really don't have to remove the wheel.
One floor jack, two jack stands, and a small piece of 2x4 lumber. One side at a time, jack the car and support with a jack stand near the jack hole but further under. With the jack under the subframe, near the coil springs is a good spot, tension the subframe against the body. Remove the bolts from both mounts on this side. Paying attention to the brake line, lower the subframe as much as you dare. I had 4 inches easily. Place the other jack stand so as to hold the subframe here. Don't place it under the control arm or any 'sprung' area that would allow further drop! Insert the 2x4 between the body and subframe to maintain the gap. Move the jack under each mount and with a socket on a long extension as a push rod raise the jack pressing the mount out of its pocket.
Lube the new rubber well with silicone or KY jelly. Set each mount in its pocket one at a time. Lay the board on top of the mount and raise the subframe with the jack to press the mount into place. Insert the new bolts with new nut plates.
Repeat.

The rear axle mounts were twice as easy to remove but twice as hard to button back up. Getting the bolt to line up with the nut in rear was frustrating. When the rear axle drops away it moves inboard and aft. Getting it up, forward and out while trying to thread the bolt caused all small children in the neighborhood to run inside.
