Wow I feel silly.... and relieved!

After multiple swapping of my spare from left to right, and casual
inspections of the front end.... I found the solution to my jerky/wiggly
steering problem.

It turns out TWO (2) tires were bad in the front.. and the belt had
broken on both.

This explains why swapping the spare didn't help anything... and me,
assuming it would've been just one tire.... well I kept looking for
other solutions.

So anyways, to all of you with drivability/steering issues...... make
sure to rule out the tires first, no matter how unlikely it may seem!

Thanks everyone,
Shawn.
