Took me a good hour and a half to get mine back in.
I decided to assembly everything on the floor thou so I can anti seize, lock tite and then torque all the bolts rather then trying to do while it was all on the car. So the weight of everything on the Subframe made it quite a bit more difficult.
I’d imagine if you put the Subframe up by itself first, then install everything else afterward it may not be as difficult or time consuming.
