In the past I've wrenched on everything from motorcycles to class 8 big rigs. So tackling the rear subframe would be a walk in the park for me if I had a lift. Thinking about it, probably the most efficient way to change it out would be, drop the exhaust, drop the center carrier bearing on the driveshaft, but leave the driveshaft connected on both ends, pull the calipers and hang out of the way, remove rear shocks, disconnect LCA's, unbolt center housing, lower whole assembly to clear subframe, unbolt and remove subframe, slide new subframe into place and reassemble.
