I'm ordered all 4 tie rod ends with the intention of installing them but I'm not 100% convinced that they are what is causing my problem.

I have a 2004 Neon SXT with 116k miles. I have a nasty vibration from around 65 to 75 mph, were it is at it's worst magnitude changes. It is not dependant on the drivetrain, it vibrates the same under acceleration, deceleration, with the clutch in or reguardless of what gear it's in (not RPM dependant). It also doesn't change in a right hand or left hand curve.

To make things more confusing, there is a load "clunk" from the front right when making a left turn like something is loose, yet when I jack up the right front everything seems solid, and I can't move the wheel in any direction.

Withing the last 2 weeks I've replaced both CV axles and the sway bar bushings. I also rotated the tires to rule that out and the lower, rear control arm bushings were replaced in January.

Any ideas what my problem is?
