I did the hard way the first time because as others have said there is not much room in there. The "easy" way (LOL I know it's not really easy it's a PITA).
1. Put the car on Jackstands and remove the front wheels.
2. Put a jack under the engine or suitably support it then remove the after bolt on the torque strut.
3. Disconnect the stabilizer links from the stabilizer bar.
4. Remove the intermediate exhaust pipe section from the Y-Pipe to the muffler.
5. Put a jack under the after part of the fwd sub-frame to support it..
6. Loosen the fwd subframe fasteners but leave on (19 mm nut).
7, Remove the 19 mm nuts from the mid-subframe.
8. Removed the 2 triangle plates at the rear of the subframe (19 mm and 17 mm).
9 Using your jack slowly lower the rear subframe just enough to access the stabilizer bar clamps and no more. If you go much lower you would have to disconnect the steering shaft and the ball joints. You can safely lower the rear end of the subframe a few inches to access the bolts. Your steering wheel shaft has a floating spline that will accommodate a few inches of movement without a requiring disconnect, just keep an eye on it.
10. Change you bushings..
11. Reassembly is the same process reversed. Torque the subframe fasteners to 95 ft/lb.
I did it the hard way the 1st time. I just changed my steering rack on my 2012 CX9 and had to remove the stabilizer bar. It takes about 45 min to lower the subframe and about 1 hour to reassemble it all using using an impact gun and power watchet. You will need 2 exhaust gaskets for re-assembly (1 Flange and 1 crush) Auto-zone had the gaskets in stock, O'Reileys did not. I had to figure this procedure out on my own with a little help from AI as no one had a tutorial on any of this for a CX9. Not HARD, but it is a major PITA to have to take so much stuff apart just to access some stupid bolts.
I hope this helps some of you
