Anyone got any thoughts??

if the alignment and balance is good, take it to a suspension shop and have them check it for damage. sounds like something is bent.

Dude that is your front Shock! Your going to have to replace it!

Possibly damaged wheel bearing (check for play and run-out) or bent control arm or strut. I'd check the wheel bearing first, the control arm is fairly stout and given the double arm suspension setup the strut doesn't really experience any lateral load like on a McPherson setup.

If the shocks are the problem then by changing into coilovers the problem should be fixed...

What do you mean by "play and run-out"??... Thanks!

Play would be any movement that isn't rotation. Jack that corner off the ground slightly and shake the wheel in all directions. There shouldn't be any wheel movement other than the steering moving a bit. It would feel like a click if bad.

Run-out is taking a measurement against the wheel at a fixed location, while the wheel is slowly rotated. The gap measurement should remain pretty constant. Think of spinning a bicycle wheel and having it randomly rub against the brake pad each rotation, that is run-out. In the case of a wheel it would mean that either the wheel is not correctly seated against the hub due to an imperfection, rust, or a bent or loose hub assembly.

Appreciate your help!!! I did it and everything checked out fine. Measurements remained the same, no noises and no wheel movement other than the steering movement.
Im going to check the control arms and ball joints since the wobble only seems to happen between 70-80mph... In low speeds the car behaves normally.
