My 2005 T&C rack started leaking about 18 months ago, pretty bad leak. I put maybe 1-2 cups of some Lucas PS additive and it totally cured the leaking seal. But now I still have the cold morning steering stiffness.
Also this week I cranked the thing to find the pump was not working at ALL. It did start back after running about 2 minutes. I have to wonder if the Lucas had damaged the pump.
I am going to get the rack replaced and then put the correct ATF fluid in and see how long the pump lasts.
Orellis is the cheapest I have found, $ 163 including inner tie rods. (Reman)
Naps is $224 reman.
Moparpartz.com is $268.8 for a new OEM rack that has a MSRP of $384
