There are sensors that control steering effort (variable assist) and also valving in some cases, one of these has a problem, I would have the system tested to see what the fault is before it developes a problem u can feel.

SOURCE: the belt that runs my alternator broke what is that belt called?

yes it is caused by your belt. now do not drive the vehicle at all until new belt is instaled. the belt is called a serpentine belt and it is the only one on the vehicle. it runs the power steering pump, your alternator, and your water pump. now keep in mind you temp gauge will not work untill it is to late because there is no colant bein sent threw your engine block. make sure to have some one put the belt on that has done it before because the belt can go a couple of different ways one the pullys but if it is not the right way your water pump could spin backwards and this will overheat your engine because the water is supposed to flow only one way due to the thermostat. so you will not gett any cooling. and i repeat do not drive car until the belt is replaced. and the correct way to route the new belt should be located under the hood on a diagram. i hope this information was helpfull to you. please rate my solution
Thank you

Most likely the problem is the lower steering knuckle. This is the one outside of the firewall, under the vehicle and it hooks up to the power steering assist cylinder. In my opinion the knuckle has to work at an unreasonably steep angle and this compounds the problem. The knuckle (especially in salt areas starts to corrode and becomes hard to turn. Toyota says the water gets into the bearing and they beings to rust the bearing and turning the whell starts to feel stiff. I have this problem and I sprayed liberal amounts of a rust inhibitor that a local place uses to rust proof cars (They sell small spray bottles of it for $5). They are called OIL TECH in Barrie, Ontario and make up their own formula. The formula has addatives that breaks the surface tension on the oil treatment and gets it into the tiny cracks and crevices on your vehicle. I sprayed this all over the knuckle, turned it back and forth a couple of times and continued spraying. I let it sit for an hour and went for a test drive -- problem solved. You could actually see the rust on the exposed parts of the knuckle. I probably will have to do this once every month of two but what the heck. It is a lot cheaper than having to replace the steering shaft ($1000+???) Probably other types of rust proofing or lubricating oils will work. I long for the old days of grease fittings and you never had to replace ball joints and tie rod ends etc.

SOURCE: how to tighten power steering belt on 1990 vw jetta

You have to get to it from under the car. Remove the plastic cover piece. There are 5 bolts that need to be loosed to tighten the belt. The bolt at the top of the bracket, the two pivot bolts going into the pump, 1 bolt that is up in the rear bracket of the pump, (bracket bolts to the block) and the bolt that holds the tensioning adjusting bolt on the front of the pump bracket. Turning the long bolt adjusts the position of the pump. All bolts should be 13mm head bolts. The "hidden" bolt on the back bracket xan be reached by using a deep well 13mm socket and a 3 inch extension. The others with a wrench or socket.

My sincere apologies for the delayed response.
I am personally going back to answer your unanswered questions.
I have only been a free contributor to this site for the past 4-months.

I do not know if you still need this information, but I am going ahead and answering it anyway.

CLICK on the following LINK. It has several Belt Diagrams, one which will match your specific engine and options (AC/No AC, Power Steering, .etc) that you will need.
To directly answer your question: YES the Power Steering Pump is part of the Serpentine Belt Route.
Let me know if this helped...
Again my apologies..
