Can anyone recommend a source of power-steering pumps that doesn't suck? I got a reman delco unit from rock auto and it's pretty much dead already. I also want to add a filter and a cooler when I re-do the pump again.
If it's under warranty, AC Delco is great at returns...personally I would just go with them. There are very few actual manufacturers so unless you are going for a high pressure setup, I would personally just go AC.
Where do you plan on plumbing in a filter?
Coolers are a great option. For OEM, you have two setups I have comes across. The fin setup that mounts right behind the grill and the setup that mounts inside the frame.
If you go to the junkyard, you'll find a ton of fin setups on GMT800 trucks and GMT400 1 tons. The hard part is finding one that isn't rusted badly.
Otherwise, OEM on the fin setup is around $100, but you could go cheaper with aftermarket ($35) and just build your own brackets.
Is hydroboost or ram-assist steering in your future? If it is, you can get a head start by purchasing the right higher pressure steering pump now.
