Suspension Problems

[coffiend]

So, my car has almost reached 100k and I'm finally starting to see some issues with it, its been perfect up to this point.

The other day, I noticed while turning my suspension was making a creeking / popping noise. It continued doing this for about a day and a half then somewhat went away.

Today driving from lunch, my steering wheel starting shaking back and and forth steadily, not a lot of small vibration, just consistently turning back and forth while driving pretty slow (about 20 MPH)

I plan on going and getting it checked out, just wanted to see if anyone here had some insight as to what it might be.

Thanks!
