How hard is it to install a k member is it something that two people can do in the driveway.

 

If the engine is in the car, it's a little bit of work, but can be done in the driveway(as long as it is level ). I did mine by myself in my garage, but I had the engine out of it. Just prepare to remove the rack, the steering shaft, and all of the front brakes, suspension, brake lines, abs sensors, etc.
