While parallel parking, at max turn ratio i heard a loud pop. upon checking noticed all of pwr. steering fluid on ground, it seems to be coming form the passenger side of the engine, the end of a netal tube which runs beack agross the other side of veh. question: what is this piece and can it be replaced by a novice.

I would say it have to be bad joints or breaks.

Steering is all electronics these days so it can only be loosen.

Did you check the fuelid level today? A loud whine indicates low fluid or a defective pump in most cases.

First thing you need to do is pinpoint the source of the leak EXACTLY, clean off all the fluid and then put some fluid in the system, have someone start the car and while the car is supported securely off the ground go under and locate the leak, wear safety goggles so fluid doesn't get in your eyes.

the powering steering hose blew the hose need to be replaced--the hose and connectors are one

Could be either a loose belt or you are low on power steering fluid,or the power steering pump could just be worn out.

your inner tie rod end either broke at the ball joint or it was not installed properly and came loose from the steering rack. Either way there should have been an issue with the steering prior to the popping noise. If there is power steering fluid there had to be damage to the rack and pinion unit and it will have to be replaced.

Dealer, but did you check the Power steering fluid level??or any leaks. There are two hose that connect to the gear box from the power steering pump. if the pump is low on fluid you lose your power steering, if the hose has a leak or it blew and lost the power steering fluid then you lost your power steering again. 
Check the fluid level to the power steering pump and any leaks or broken hose to the gear box.
Keep me posted, be glad to help and good luck.

you have a rack and pinion problem

The only four rotating items under the hood are
engine
power steering pump
A/C compressor
and smog emission pump.
==== I would check the fluid level on the power steering first. Check for pink fluid leak on the ground,
==== Check the A/C system with the wheel turn to one side and APPLY ALL LOADS.
Example: high beam on,A/C max,radio on and deforster on.
This will give you system a stress test.
All eyes on the pully and locate to part that generate the loud screeching noise.
My bet is on the power steering pump.

Please post more info on the comment window.
I will follow up on it.

this is a guess but the inner tie rod and tie rod end (you have one of each on each side of the truck), wear out and make a loud clunk, mostly when changing direction, but also on starting & stopping. ABout a $200 repair including a front end alignment.

Call at least 3 shops for an estimate including your Ford dealer.
