I have a 58 Impala with a 348 and it has the original style power steering. I switched to an alternator and mounted a new power steering pump on the block. Problem I have is it now steers so easy, it's like the wheels are off the ground. Also, the control vave is now leaking bad. Do block mounted pumps put out too much pressure for the old link type systems? Bought the pump from Late Great so I assumed they would know what pump was needed. Any help would be appreciated.

I would replace the P/S Control Valve,it's best to replace the valve instead of re-sealing and it could be the valve causing the easy steering

Here's a link to a Valve.

OK here's a link for a seal kit for your valve,also could be a P/S hose leaking

Did you have easy steering with your first valve ? Your easy steering still could be your P/S control valve.When the F!!d Expedtions first came out it had easy steering and we replaced the gear. As for the pump it could be the Pressure Flow Valve inside the pump

I would see if you can get the correct Pressure Flow Valve and Spring .They are real easy to change,remove the H/P line from the pump and then remove the fitting that screws into the pump and valve and spring will pop right out.

The 1,300 psi is to much pressure for the P/S Control Valve and that is why the valve is leaking.You need to re-seal the valve and install the proper pump.
I found an old pump from a 63, 6 cyl. car. I'm going to try your suggestion and change the pressure/flow control valve in my pump. I ordered the rebuild kit for the steering control valve yesterday. I'll post the results of these changes next week. Thanks again for your help Jim.

In 63 was the control valve mounted on your steering linkage ?

OK then the pressure flow valve & spring should work,I would test the power steering before re-sealing the control valve.

Seon, the tri-five and 58-64 have different frames.The steering linkage & gear on the tri-fives is mounted in back of front crossmember and 58-64 is mounted in front of the crossmember.
arkyduck: i have been running it for about a year now. i made the brackets and so far working great, have about 600 miles on it, all in town.
i did not rebuild the cyl. i have a 8-10 oz. remote tank. i have 7in. of tread on the front tires and it is better then the stock pump.
the fitting that go on the cyl. are a little pain in the butt but work able.
if you need more pic's i can get them for you.( now that i cleaned them out)
thanks to jim.
hope this helps mike
