LEFT FRONT TIRE SHEAKING

Please have this checked out as soon as possible. Either you, a Mechanic, or an alignment shop, need to check out the front-end and all four points. Something has changed, broke, or is loose and worn out. Check: Ball-joints, wheel bearings, tie-rods, rims, lug-nuts, tires, tire balance, tire inflation, tire tread wear, alignment, U-joints, shocks, and suspension. Let me know if I can be anymore help, good luck.

Have a tire shop do a full front end inspection

Make sure your tire is inflated properly. Jack the car up and spin the tire and check that you don't have a bent wheel. after that bring it in to a tire shop and have them pull the wheel off and put it on their balancing machine. It may be out of balance or have a broken belt in the tire

Tires out of balance? Start with the simple things before changing stuff like axle shafts. Take the car to a tire shop and make sure the tires are balanced and the rims aren't bent, as either one of these can cause a rough ride

Tire bouncing (not shaking) is generally caused by a bad shock absorber. If you have 30k miles on them or you see any oil leaking form the top (but could be long gone), replace them. (front pair, rear pair, all four but never just one) If it's shaking, check ball joints, all other front end components and wheel balance.

if the left tyre is shaking then check wheel nuts ,but without a good look its difficult to speculate but i would suspect a deformed tyre which would be caused by the sun but in extreme circumstances freezing conditions might possibly cause it as well

SOUND LIKE BAD WHEEL BEARING.SAFELY RAISE SUPPORT VECHICLE ON JACK STANDS. GRAB THE FRONT TIRE WITH BOTH HANDS ONE HAND ON TOP TIRE OTHER HAND ON BOTTOM OF TIRE. TRY SHAKING TIRE.IF SHAKES LITTLE WHEEL BEARING BAD.IF DONT SHAKE WHEEL BEARING OKAY.

If the Tire is shaking all the time check the tire rod ends, If it shakes when your braking especially at higher speeds check the run out on the Disk Brake could be warped, look at spring housing for strut

There are many things that can cause front end vibrations, I will give you a list and hopefully the information provided will allow you to narrow it down. Usaully front end shake is caused by a tire that either has a shifted belt in the tire or the tire weights could have falled off and the tire and wheel must be rebalanced, another reason for shake is if the shake occurs when applying the brakes it is a warped rotor and the brakes must be replace in the front end along with new rotor installed, the last thing that it could be is a loose or worn out front end part perhaps a tierod end. If i was you I would try rotating the tires from the front to the back and see if the shaking goes away if it does it is most likely a bad tire (shifted belt) or the tire needs to be rebalanced at a auto garage. after checking that first then jack up the front and grab the wheel and move it back and forth up the down to check for play or loosness, as I said if the shaking occurs while applying the brakes replace the brakes and rotors.

Usually shaking of the steering wheel brought on by going over a 'bump' is caused by a suspension component problem. Since u just had the brakes done (no history of this type problem before?), I am wondering if possibly something was not tightened properly during the repair (this would have the same effect of a worn component). I would bring it back (carefully) to the service facility, and ask them to check the front suspension components, and explain what happened while driving.
U could check a couple of things yourself, if u want. Jack up one side of front of vehicle, place on safety stand, grab tire at 3 oclock and 9 o'clock positions, try forcing the tire as if u wanted to turn the wheel to the right, and then left., U should not have any 'play' in the wheel. Next, grab the tire at 12 o'clock and 6 o'clock position, try to force the tire in and out . There should be no 'play'. Repeat on the other front tire, if you have movement when grabbing and trying to move the tire, u need ball joints or tie rods. A slight bump in the road should not result in what u describe unless something is seriously wrong. Have this checked asap, as this is not safe. Let me know what u find.
