Worn tires wobble all day long and balancing or alignment won't touch that. The new struts because of added damping simply damped it up until they got a little loose, ALL shocks and struts loosen up some once they get in use a little bit.
Axles? Find a quiet parking lot and then steering to the limit and turn in constant circles left then right, you'll know then if it's axle. Axles binding from wear in a straight ahead direction are almost ALWAYS wrecked in tight turning, they will be clunking away. The extreme angle change then forces a hard pop over the straight ahead wear pattern. If not clunking or clicking it's not axle. As far as an inboard support bearing or CV joint, they almost always will make noise with any wobble to let you know what kind of problem is there.
Put each wheel in the air and a hands at 9 and 3 o'clock tug on the tire, looseness says tie rod which will wobble depending on how it is loaded driving.
I have another thread entry here close to this about rotation of tires on FWD cars and why I NEVER rotate as a matter of practice. It leads to just this issue if one of tire. Very common, I haven't seen a FWD car that didn't do it yet, it is inherent in the design. Yet nobody on the planet addresses it, other than to tell you you need 4 new tires, and that then wears out the 4 new tires quicker too. Go here and post #4
Gravel roads present special issues. There is really no sense in balancing a tire that runs in gravel, the constant sticking of rocks in the tread will trash the balancing on an ongoing and constantly changing basis. Why I quit balancing years ago, my back drive is gravel. Waste of money, the wheels were checked for minimum out of balance themselves and then the tires just don't get it. The cars run smoothly up to 75-80 mph and all I need, yes, I can tell the slight difference in smoothness but not much at all and the tires still go max mileage. Here in Texas it will always be heat cracking or tire damage from road junk that takes them out anyway. The thing I said above about rotation has far more to do with tire wear than balancing, I have proved it out way more than once now.
