Difference between 87-93 power steering pumps?

[04sleeper]

Does anyone know if there is a difference between power steering pumps between these years.

I see them sometimes advertised as 85-89 and 90-93 and showing different part numbers for them?

Also I remember years back driving a new 93 and the steering felt much nicer than my 89. Is there a difference or is it something else?

As far as i know, some were black and some were orange in color.

That's about it really.

Hmmmm. I was wondering if the newer ones were any better. Usually when Ford changes something to newer it for a reason. Is color the only reason?

i recently upgraded my powersteering pump... it used to be that yellow/orange color, the replacement pump i got from ford was grey/black. i don't know if it was just the fact that my pump was going bad, but the new pump feels much softer and easier to turn than the old one.

Thats what I was thinking. So the grey/black one is better.

Thanks wild50gt

Anyone else?

i was told that there were slight line pressure differences made throughout the years. perhaps that has something to do with it.

i also cant remember anymore whether the quick ratio racks use a different pump, and whether the Ford and TRW racks use a different pump from one-another.

Thanks HISSIN.

Anyone else have any ideas?

I'd like a few more opinions.

Thanks

The pump on my '87 is blue. It whines like hell too when people ask what the noise is I tell them I have a blower. I am interested to know as well if there are differences I need to swap out my whining pump since it is getting worse the colder it gets out.

Not to jack the thread but what about the difference between 4 cyl and 5.0 pumps? They are phisically identical as far as I can tell so I used the one off of my 5.0 parts motor for my v8 conversion in my 93 mainly because it was black. The one on the 4 cyl was like beige color. I have heard some poeple say that v8 racks arent compatible with 4cyl pumps. So is the 5.0 pump going to be compatible with the 4cyl rack?

I don't think color matters, i have replaced mine twice (long story). One was black the other one beige colored...also as far as i know the quick ratio racks use the same pump, the rack is just geared dif.

as you know, Big J, many pumps whine out of the box. it lets me know the serpentine belt is still attached.

Lets see if anyone else chimes in.

Guess that is one way to look at it.

Its fords fault, its impossible to get the pulley on without damaging the pump!?!?!?!?!

the end of the pulley often becomes 'mushroomed' after being on a given pump for any period of time. this keeps the pulley from seating properly upon reattachment on a new pump shaft.
if in doubt, i might swap a new pulley on. they can be had for under 20 bucks, as i recall.

Yea your not kidding when you say pulleys are a PITA to swap...Was flushing mine and broke the plastic fitting for the return line off , I just went to a wrecker and looked around and found that power steering pumps on all model of fords within about a 10 year span were identical, just different bracket and pulley, I pulled one off a big LTD and works great, just about no whine
