Replacement of wiper spindle is not such tedious but all thing you need is proper tool kit otherwise it’s so time consuming. Earlier, I also have gone through the same situation when bought an aftermarket wiper spindle http://www.iautobodyparts.com/dodge/ to save money and tried to replace it myself at home. Believe me, it’s not that easy as it looks, eventually I had to made replacement with the help of repair person. Consequently, I would only advice you to hand over this task into skilled hands.
