BTW, the Steering Rack Bushings are the Easiest thing to do on the whole car, practically!! I, of course, overthought it beforehand as I always do, but once under there, it couldn't be easier!! On the 07'E63, just raise her up, unbolt the Steering Rack (4 Bolts) Plate, at this point the rack will just be sort of floating. The bottom bushes are straight forward, just maybe use a screwdriver or something to pry them out and use soapy water to lube up the new ones and shove them in, but don't do that just yet. The top ones are a little more challenging. I used a small screwdriver to push them up from underneath where the lower bushing was, thus the reason why to leave the lower ones out. Using a headlamp helps here ( I use one at all times!!) to see exactly where the edge of the upper bush is to push on and viola, it pops out. You have to drop the Rack just a little for clearance to remove and insert the upper bush and then follow suit with installing the lower and your done! Install the bolts, tighten to spec and Finito!!!
