Firstly, I don't have a "problem" I am trying to solve, per-se. ATF+4 (spec) seems to be working fine for my Rams. It is however not a secret that pumps tend not to have spectacularly long lives driving the steering systems on these trucks. Not like they blow up in 10 k miles, but do get weak in the 70k miles range sometimes. Not an engineering issue really. Just a lot of work to do, especially on a big tire truck that tackles off road situations.
I am about to upgrade both to the "later" more powerful pumps. They both already have the giant steering boxes Mopar offers that I've been told are from the Ram 5500.
Worth noting that the power steering pump also drive the hydroboost brakes as well, so weak pump means weak braking. My stick Ram is starting to get heavy steering at low rpms. This is where I need assist the most, as it handles a lot of heavy trailers in tight spaces. This is probably exactly the stress that has taken its toll.
Anyway, I'm looking for something that maybe would help the new pumps last longer. Something with greater fortification maybe?
Pumps themselves are Saginaw TC type pumps that are used in about a million different vehicles.
Probably going to do a new PS cooler with fan for the low speed work too, and a filter.
Appreciate all input. Thanks.
