Power steering pump
Hey all,
I have a 1983 f150 with the 302 motor in it. Recently my PS pump has been leaking and I need to replace it--my question is how hard is this job and is there anything that I need to be particularly aware of before I undertake it?
Thanks again!
Michael

No, it is not hard to change, can be a little messy depending on how much fluid is left in the system, but, is it the pump or the lines that are leaking? The lines will have to be disconnected any way might want to replace them at the same time IMHO.

Thanks--I anticipated the mess, though at the rate its running out of the bearing seal on the pump, there may not be much left in there... Is it true that I need to prime a new pump by hand before I install it? Its definitely leaking from the pump (shaft seal/bearing), as far as I can tell...
Thanks again for your help

I have always installed the pump and lines, filled the tank to the full cold line started the engine turned the wheel to the left, shut down the engine, topped off the tank, restarted turn all the way to the right, then recenter the steering shutdown and fill as required, then keep an eye on it for a few days as the rest of the air bleeds out. You should be good to go after that and get back on your normal servicing schedule

on my 86 the middle bracket is aluminum. Lets just say I had to buy a new $80 pulley cause no one had it and a new pressure hose. Also broke one of the aluminum eye holes off said aluminum bracket even after using the "blue" wrench to help it along.

You want to get rid of as much of the old fluid as possible. New pumps hate old fluid. To get rid of the old fluid, put the front on jackstands and turn the wheel lock to lock (vehicle off) with the lines disconnected and have a helper let you know when the fluid is done flowing out. Leave the front up on jackstands so that when you install the new pump/lines, you can use the turning lock to lock method to bleed the air (vehicle off). You want to air bleed the new fluid as much as possible with the engine off before you repeat it with the engine on. You don't want to come anywhere close to risking a dry pump with the vehicle on.
Other things to pay attention to: check the capacity and fluid type in your owners manual. For instance, my '79 uses Type F transmission fluid for power steering. I don't want to go putting power steering fluid in a pump that doesn't want it. You may find that your truck is the same, I'm not sure.
