I also used the factory bottle jack to install mine. I attatched the axle end of the lca first then raised the frame end up to see how far I needed to push the axle forward. Doing it this way also allows you to see the hole and know when it's lined up. I put the base of the bottle jack against the axle at the lower shock mount and the top of the jack against the bracket for the frame end of the lca. Then just crank away until the holes line up and slide the bolt through. I had no problem at all doing this by myself, it may have taken me about 5 to 7 minutes per side.
