There is a special tool that actually pulls up on the shaft and also pushes the pulley down at the same time (I used to work for GM where we made the power steering pumps...( for almost every manufacturer in the world....Chrysler included!! ).I have seen millions on the assy. line - (actually did repair work too!) The shaft MUST be held in "free space" because if you try to press on a pulley without this tool you WILL BREAK things inside the power steering pump..such as the pressure plate, the thrust plate, the thrust plate bearing..just to name a few,, and you CANNOT take it apart to change it.. The pulley is the LAST thing to be put on.. (its tested without the pulley).. once it passed all QC/QA.. the pulley was installed if the pump was purchased on it.. (some where shipped without and installed at a sub-assy point). Your local dealer should have one..
