Inspect the front tires they may have a bubble on one of them it is possible that a wheel bearing is going out but the easy check is to inspect the tires after you have driven it a few miles
check the balancing on the tires.
Check the tires for cupping. If you have had an alignment problem the tires could be cupping and will make quite a lot of noise. It could also be a wheel bearing.

The steering wheel shimmering could be warped front rotors, when slowing down. The stalling when slowing down could be a bad fuel filter.
Most the time that means it needs a front end allignment. Possible bad front tire or wheel.
most of the time when a u-joint starts going out it will make noise in rewind first

My Hyundai Elantra 2008 GLS with 13,800 miles on it had a vibrating rattle especially when idling but also while driving although not always. I bought the car used. After four months of going crazy with the sound we found that it was coming from where the back seat joins the frame. It is not tightly joined there nor is it cushioned. We stuffed some thin cardboard around it to tighten it. That keeps it from vibrating and rattling.
maybe you dont have enough power steering fluid This is also a symptom of a neutral safety switch / transmission range sensor going bad. See "Related Questions" below for more
