Loose wheel or tire under inflated or tierod pooched or wheel bearing gone .
yes
Stabilizer rod may need replacing,they are right behind the front tires,might as well check both sides.Could just need tightening.
cause you might not of put tighten the tire when you replaced it . or your rim is bent, did you hit a curb?
One of the shocks on that side is probably bad.
I would say the drve train would cause a vibration. A wobble could be from a bad tire, unbalanced tire, bent rim, bad tie rod joint.
Check the steering arms, the tie rod ends, and the ball joints for wear. Any of these will cause the problem.
Worn sterring and suspension parts. Put it on a rack and inspect all parts.
front drive shafts maybe
tipicaly lose lug nuts or a bad CVC joint & axle or a bent wheel, or a tire that's starting to go bad. or a warped rotor. Have your brakes checked
More than likely... the power steering belt.
Worn out tie rod ends ,idler arm, and Pittman arm would be the most suspectted culprits, but control arm and stabilizer arm bushings are also contributors to wobbling front ends!
I would have your exaust pipe looked at, it might be loose, or might even be missing a bracket.
