There are odd popping noises when I turn my wheels tightly

What is your question?

I have owned a 1993 Toyota Corolla for one year now. It is a four-door, manual transmission. I was traveling in some rainy conditions and noticed that my steering wheel started to shimmy. I could minimize the shimmy by slowing down. However, as I got into town, I noticed that on fairly hard turns, there were popping and groaning noises in the front-end of the car. I was hoping it was only power steering fluid so I followed the owner's manual for assessment and all fluid appears to be normal. Is this a bigger issue with the transmission, struts, steering controls, etc?
