I've got a 2004 Dodge Ram AWD Quad cab with the 5.7.

I have developed a leak/crack in the power streering cooler unit.

Not sure if anyone has one availible since nobody offers a direct OEM replacement for them.

 

When I bought mine last year or so, the only place I was able to find a replacement was the dealer. I think it cost me around 105 dollars and it is easy to replace.

 

You can download the Parts Manual from the links in my sig and use it to price shop one online or from the dealer. The should be avail at auto parts stores also and there are plenty on Ebay and salvage yards should be no different

Are you sure it is the cooler and not the hose (weak clamps) coming into and out of the cooler
