power steering won't turn left

It just started getting very hard to turn the wheel to the left. Turning right works Just fine. Can anyone offer some suggestions? thanks.

its very possible your power steering rack is due for replacement. Double check that you have no leaks on the rack itself and no rubber hoses disconnected from it!

what make year miles???

Thanks for the info. Car has 115,000 miles and I am going to have the rack and pinion replaced.
