HELP! I'm running out of ideas

I picked up the other dust seals and they worked perfectly, I installed new bearings (inner and outers) on both wheels but the problem still exists.

I tried what "eestatic" suggested and lifted the car, put a lever under the tire and moved it up at the 6 o clock position, while holding at the 12, but I can feel no movement.

I only feel the vibration/clunking when I turn into a longs sweeping turn like an off/on ramp or a clover leaf and only at speeds over 20. I tried turning tight circles in a parking lot, but I don't feel anything then. It is hard to tell if it only happens when turning right, pretty much every long sweeping turn around here is a right hander (off/on ramps etc.), so I'm not sure if it is only turning right.

I've had a local mechanic look at it earlier in the summer and he said all the ball joints and tie rods etc seemed fine, he pointed me to worn out strud rod bushings (which have since been replaced, along with all the other stuff I did).

I think my next move is to get a professional alignment done. If a tie rod was bad, I should be able to feel play when moving the tire side to side (push, pull at 3 and 9 positions) right? The problem does feel like I imagine a failed tie rod feels, like the wheel is trying to straighten itself when in a tight turn, causing the clunking/wobble/vibration feel I'm having.

Can a bad wheel alignment create this same sensation, but still track straight and feel normal even at highway speeds?

Anyway.... I am going to get my new rims and tires mounted and balanced, then I'm switching out my leaf springs and shocks in the back and then I'll get it aligned to the below max performance street alignment specs. (at least as close as I can get to it). Unless someone has better suggestions?

I appreciate the responses.

Bad wheel alignment can create the sensation you describe. Negative caster can cause a shimmy at higher speeds. Like when you push a shopping cart really fast. Notice how the high caster angles correspond to the more aggressive driving.
