Problem: creaking and later popping noises from front end when driving over uneven roads and speed bumps. There was also some front end instability which showed up as a tendency to wander slightly on freeways.
I was concerned about worn ball joints which can be very dangerous if there is a failure at high speed. A reputable car shop told me they were fine, but the noise worsened so I replaced them myself with new ball joints purchased from a Lexus dealer. The old ones were hard to get out, and I had the car re-aligned after the repair.
The old ball joints were VERY worn with a lot of looseness and play. After replacing the ball joints all the front end problems disappeared. No more creaking, no popping and steering stability was fully restored.
