I have read all the comments. I was curious and decided to call Borgesons customer service department and ask some questions about the issues described. The Borgeson employee was quote "unaware of the k member interference issue" and "unaware of the newest mentioned problem of the large shaft pitman arm washer, nut, fit". Very curious, not good. She said she would call me back, surprise, she did not! Its great that members are trying to fix this issue themselves but its the manufactures responsibility to own up to and fix problems like this quickly. Moparts members call Borgeson 860-482-8283 for your fellow Moparts members that have bought this product and lets fix the problem.
