I have the earlier Lifeline one with a Brooklands (Riley) steering wheel. It used to be a pig to get it off and on until I cleaned up the heavy milling/broaching marks on the splines on both wheel and column part with a warding file. Now as long as you line up the broad spline nearly correctly, it slips on perfectly every time, without the binding and jamming it used to suffer from. I use copper grease on the splines.
