Wheel vibration at high speeds and creaking suspension

I bought the vehicle listed above 9,000 miles ago and during a pre-purchase inspection a mechanic noticed a minor vibration when accelerating. He pinpointed it to the left and right front axle shaft assembly so a mechanic replaced the CV boots, CV joints, and left/right axle. Everything was fine up until 109,000 miles I started hearing suspension creaking when going over speed bumps, which now occurs over any minor bumps really. It sounds like it's coming from the front left side but more towards the center of car. I also started noticing vibration/wobble in the steering wheel at higher speeds (65 MPH). I've had one mechanic say the vibration/wobble was from unbalanced tires (it wasn't. Still occurred after balancing) and another say front inner joints being worn out was the issue and should replace both front axles. I don’t see how this is possible if they were replaced 9,000 miles ago? Anyways, I had yet another mechanic say the creaking in particular is likely from the struts, but I'm not so sure about that either. There doesn't seem to be any residual bounce after bumps and I don't see any leaks. Though they are pretty rusty. I'm curious what could actually be causing the creaking and the wheel wobble... Something isn’t adding up here. Looking for the suspect part.
