powersteering pump

last yr. had trouble keeping steering belt tight. Replaced this spring and it still sings and steering wheel jumps with tight turns. Is it my pump not the belt?

there I corrected your typo spelling error in the title as i figured it was a pump not pomp,LOL

I've tried the same pump in two different vehicles and found that the wheel would seemingly randomly get 'tight' for an instant if turning a sharp turn.

Back in the day that was called Power Steering Pump Catch. 70's Chryslers were notorious for it. Just go ahead and replace the pump. Those CII pumps were bad about getting noisy as they aged. Ford used 'em on everything until I believe 2004. Try a late (mid 90's) one from a salvage yard first. If that does not work, then parts store. You will have to change the pulley to your V-Belt set-up. Just rent the tools from AutoZone or somebody. Ford began using them in 77 as the universal replacment for both the Eaton (small/medium cars) and Saginaw (large car/truck) pumps. You will find all the hose fittings are the same as well so no problems there. In fact, when the PS pump on my wife's 84 Volvo went bad (it was a GM Saginaw design) I used one I had sitting around that had come off a 80 Buick Electra with 4.1 V6. It bolted right in with the same size/thread (metric) bolts the Volvo used and the hoses also fit with no adaptations needed. Even the Volvo PS bracket was identical to the GM one. So there is a lot of interchangability between brands. That's why I say ANY CII pump off ANY 77-04 Ford product will work with a pulley change.

Cool!

After installing the pump, leave the belt off. Spin pump by hand for 20 or so revolutions, in the direction of the engine rotation. Turn the steering wheel a quarter turn in any direction.. repeat spinning of pump, filling as necessary.. Repeat procedure until you turn the wheel against the stop. Then go in the other direction fully, alternating between spinning the pump and the wheel.

The aluminum Ford pumps are VERY susceptible to noise. Once they start groaning, they never stop.
