When I purchased this 2003 2500 4X4 cummins the power steering fluid was low, so it now has regular power steering fluid mixed in it. Just found out you need ATF+4. Should I drain the whole system and if so what is the easiest way to drain all the fluid?
Yes, drain it...I believe you can remove one line from the pump (the return line) and shoot it into a bucket while someone else adds fluid at an idle...I have read where normal PS fluid causes issues in the newer rams for some reason...
