You are going to a lot of extra work on this one. We always loosened the fan schroud and let the motor and subframe fall each side one at a time. Except for bleeding the brakes the whole job doesn't take more than an hour with experience.
Remember you should do a front end alignment afterward as the relationship between gearbox/idler arm is moving relative to the steering arm at each wheel.
