power steering pump
I have yet another fix on my 89 f150 4.9L 6. It had been stalling when I turned into tight parking spots etc. and it whined when I turned. I checked the fluid and it was a bit low but not too bad. I filled it up and I developed a chirp until I drove about 20 miles. The other day the chirp stayed longer and eventually began to squeal. I took the belt off and free-handed some pulleys to see where exactly it was coming from. When I turned the PSP pulley, it slid back about 1/8 of an inch and was kind of wobbly from side to side (bearing?). Should I replace the pump, or is it easy to rebuild? Difference of about 15 bucks but I have heard rumors about presses and things that I don't have in my hillbilly auto shop. Any suggestions?

Power Steering Pump Pulley removal and install info.
You can do what JCMS says
or
buy a direct replacement PSP from an auto parts store.
As JCMS says; you will need a PS pulley removal tool to take it off and a different installation tool to re-install the pulley, usually these tools come in a PS tool kit and you can rent one for free from certain Auto Parts Stores.
Remove the Pulley before you remove the Power Steering Pump from the bracket and install the pulley on the new PSP after it has been installed.
Remember; the two round halves of the removal tool,
go around the end of the pulley, and the round collar slips over the two halves, use the short fat bolt with thick washer to pull the pulley off.
(This fat, short removal bolt will not be screwed in the PSP shaft, only used to push out with)
Advance Auto Parts will sell you one of their PSP Pulley service kits and when you are through with it, return it and get a FULL refund, that is their policy.
TAKE a digital PICTURE of the PULLEY BEFORE YOU REMOVE it from the PUMP
or
MEASURE the distance from the end of the pump shaft to the pulley, approx. 1/16" to 1/8" of the PSP shaft will be sticking out. (See picture)
The pulley MUST to re-installed exactly the same or the serpentine belt will wear rapidly on one side because it is not lined up with the other pulleys.
The electrical SWITCH on the PS hard-line located on the left side of the radiator, above the PS Gearbox may be bad if your engine is stalling when idling and turning your front wheels, the switch increases the engine RPM when the wheels are being turned at idle.
My electrical SWITCH started leaking PS fluid through the diaphragm,
it took me a long time to figure that one out, because it ONLY leaked when the engine was OFF.
Hope this helps!

I know this is on old topic but I think that this is the answer I need
My belt is wearing to the front and it looks it wants to come off the front
Looks like someone tried to replace pump and they did not put the pulley all the way onto the shaft.
I hope this is the problem I am excited to check and see
