Sometimes in 2-wheel drive I get a jerk in the steering, which turns into a constant wobble?

I have seen the front CV axle go out and cause this problem. here is a video on a similar vehicle that shows the job being done. Also, I have included the instructions on how to fix the problem on your car in the images below.

What happens is the CV joint wears out and tries to lock up. When you put it in 4wd it forces the joint into a new position which resets it, so the problem goes away for a while until it slips back into its worn-out spot in the joint. Check out the images (below). Please upload pictures or videos in your response to the problem so we can see what's going on.

Thank you, that makes sense.
