If you are renting the spring compressor look it over real good!! Having one break when your putting it together gets rather exciting. Or have a floor jack under it as a safety until the ball joint is bolted back in.As long as you have a good spring compressor it'll be a RR itself. Remove the shocks, unbolt the end links, compress springs, loosen ball joints, remove/install one arm at a time, put it all back together. This will also be a good time to swap springs if needed too.
