I have two floor jacks so I put one on each side of the stock k-member, unbolted it, and lower it down a little at a time on each one. Placed the tubular on the floor jacks, lifted it, and bolted it in. With one floor jack it will want to roll to the back so you would have to get creative but not impossible. My two floor jacks are a regular one and then a smaller one that I use just for general maintenance. The stock k-member weighs right at 50 pounds and depending on which tubular k-member you install they can weigh anywhere from 10 to 15 pounds less.
