What is between the ac unit and powet steering pump on 1995 f350 7.3 diesel

Do you need to replace an existing pump or is your car currently manual steering? If it is manual steering there will be more than just adding a pump. The actual steering rack is most likely different from a power steering unit so there would be multiple components required to convert. If your pump is faulty, you just need to disconnect the lines, remove the belt then remove the pump and install the new one. While you are doing that I would flush the old fluid out of the rack to increase life span of steering rack.

Said "knock" could be in the AC compressor or power steering unit since it don't knock with belt off.

The vacuum pump in the Dodge W150-350 Cummins Diesel is integral with the power steering pump on the driver's side of the engine. remove it as one unit from the accessory drive unit. Then you have to press the gear off the shaft to separate the power steering pump from the vacuum pump

You may be having AC problems but that is not what happened when the Steering locked unless the AC is on the same belt as the Power steering unit. That whining you are hearing when you turn is actually the power steering unit being low on fluid or the power steering pump going out. Based on what you have described my guess is that the unit has gone out and needs to be replaced. As far as the AC compressor is concerned, if the unit is low on Freon it will not engage once it gets too low unless the clutch goes out. When you look at the center of the AC compressor when the engine is running and the AC is off you should see the pulley free spinning and the very center of the pulley won't be spinning, that is the clutch Dis-engaged. When you turn the AC on the Clutch should engage and allow the compressor to work. You will hear it kick in and kick out repeatedly if it is low on Freon. If it is too low it will never kick in because the low pressure switch won't allow it.

diesels do not have conventional vacuum operated brake boosters. i am not sure what chrysler calls there system, but i believe it is similar to the gm hydroboost system, in which case pressure is created by a pump integral to the power steering pump gives you your assist, and fed to an accumulator on the fluid booster near the master. be very careful when tinkering when these systems, as they can have very high pressures in them even when the car is not running. are you experiencing any steering issues at the same time? check your fluid levels (PS fluid will effect operation) and all the associated hoses and lines, go from there. good luck!

YOUVE GOT TO BE JOKING

Check with the junkyard where you got the pump...you may need to change the pump bracket with the pump, or use a different pump.
You don't have a separate tensioner the pump is on a slide mount and is the tensioner (why the parts guy is a parts guy not a tech).

no special tools are needed

Yes you might have to alter the connector to the motot a little but that is normally not a problem
