Generally the front steering wheel shaking is due to the front wheels/suspension, the rear wheels cause the floor or seat to shake. Since you are getting both:
First I would question the job done by your wheel balancer. Many places do not get the balancer in balance.
Next, use a micro gauge on that drive shaft, DO NOT RELY ON LOOKING.
Look at your tires and feel the tread area. Look and feel for cupping, small pieces being scuffed off. Check the front wheel bearings and the 12-6 for wobble and 9-3 for wobble. Check run out and test the ball joints for slop.
With the rear wheels test the rear end for movement through the pumpkin. Test the rear wheel bearings and suspension. Check inflation of the tires make sure they are close to each other and the fronts. Check for any shimmying in the geometry of the suspension. Test for tire wear, cupping.
If everything seems OK, re-inflate your tire to the max listed on the sidewall and run them for a while at that inflation and look for excessive wear.
Most tire shops leave a lot to desire when they work on your tires and wheel assemblies. They are too lazy to turn tires, clean the inside of tires or even remove snow, ice and water.
If you get no satisfaction from the balancing of your tires buy ceramic tire balancing beads that are put into a tire via the air valve, these will automatically balance a tire while the tire is rolling. Or at the very least seek out a good dealer by asking your tire manufacturer to recommend a good dealer.
The statement about tire shops comes from my own experience with many shops in trying to balance 5 wheel assemblies in vain to the tune of 55 tire balance trials. The end result was Bridgestone recommending a certain shop where it was done once.
The other Firestone, Bridgestone and independent dealers all used similar balancing equipment and all were out of date and non certified for balancing. My investigation and contacting at least 2 makers of the equipment lead me to the fault.
I have taught automotive classes and it is unbelievable what some people think of as "in balance" and it is many people like these students that man the tools that do the job for us.
Some professionals are simply unworthy of our trust.
