While driving car mad a loud screeching sound,

check the condition of the ac and power steering drive belts

Sounds like a belt--
Belt provides rotation for the power steering pump, alternator, and water pump.

Hope this helps!

Hi Ron, that is a little of a mystery. Have you noticed any leakages from anywhere on the units? If the answer is no, has the system been bled correctly? If not, lets try that. Make sure that the steering fluid is at the correct level in the reservoir. Make sure the belt driving the pump is sufficiently tightened and not slipping. A slippage is usually identified by a loud screeching sound. If that is what is happening replace the belt and maybe the tensioner if it is automatic. If it has a tensioner, tighten it. With the engine at idle speed turn the steering wheel until it reaches its maximum lock to the left and hold it for four seconds and then turn it the opposite lock and do the same. (Holding longer will cause damage to the pump). Continue the bleeding operation observing and feeling for an improvement. Regards John

sounds like it

Hi, it sounds more like you have a improperly tensioned drive belt. If you didn't get all the trapped air out of the power steering system this maybe the cause of your stiffer steering problem now. Try loosening the P/S belt all the way and starting the car if you still hear the noise you know its in one of the other drive belts. good luck

If your C/V joint is going bad it will make a nasty clicking sound and get louder the longer you leave it unattended.If this noise went away it could have been something stuck it the moving area of your wheel and just worked itself out.Keep an ear out for the noise to return,it it dosen't come back be happy.

the belt that drives the water pump also drives the power stearing pump and it was locked up and not allowing it to spin fast enough for it to work or the belt broke

If The Noise I Coming From Under The Center Of The Car You Have A Bad Rack & Pinion

sounds like it is out of fluid if you fill the fluid then turn the wheel to one side and hold it you will build up pressure and see where it leaking from.
