I recently purchased a 2001 Grand Caravan. I an getting ready to put a new rack in it due to the fact that the power steering has been acting up and the inner tie rod seems to be worn out. In a manual I have, it says you need a roll pin removal tool to remove the pin from the steering shaft coupling. I never recall needing such thing on any other racks I have replaced. If this tool is nessicary, where can I get one. Just want to be prepared before start. Thanks.
