The power steering reservoir has a dipstick attached to the cap you take off to fill the reservoir, it is written on the dipstick what level is normal. Low fluid will not cause any play in the steering worn parts like tie rod ends and worn steering gear boxes will.

Is it leaking out of the reservoir itself,or is it leaking out f the reservoir cap? If the power steering is overfilled, it will leak out the vents in the cap when the fluid gets hot. It may also be a bad seal on the cap. Replace the cap if the seals are bad. If the reservoir itself is leaking, the only option is to replace the reservoir.

Clearly this is fluid from your power assisted steering. You will find that teh pump is run from a fan belt that comes off the main front pulley and you should be able to track this back to the (Now empty) power assisted fluid reservoir) Topping it up will probably get it going in the short term, then you can go hunting for the leak

into the Power Steering pump, the reservoir is at the rear

Check the power steering fluid level.Allso check the master cylinder level.Witch ever is low is your problem k

Find the leak and repair it...It is a sealed system, if you are adding large amounts of power steering fluid, it is leaking out somewhere. Hoses, reservoir, steering box, power steering pump are places to check. You should only have to add minimal fluid to the system for the entire year.

The immediate squeal you hear is most probably the unit is out of fluid or has leaked onto the serpentine belt and causing it to slip.
Fix the leak and check your serpentine belt for wear.

Make sure the fluid level is OK, if reservoir MT ad, with out the cap till air comes out and fluid gets in to system, turn the steering right to left wile You add fluid with cap off, till fluid is not longer going down and reservoir inside gets quiet, when fluid level is OK, put cap back and try it, if system did not recovered normality and loud noise comes from the pump, pump needs replacing, if steering is steel hard, no noise comes from pump, look a steering box or steering arms, if truck has Rakenpinon, look for broken boots, pit man arm
