So after doing this for a couple days, I noticed that there is a clunking sound coming from the back. It only happens when I'm moving, and is especially bad going around corners. From what I've read so far, I think the CV joints or bearings are the problem.
I checked under the car and there is about 1.5 inches of "in and out" play in the "rods" that turn the back wheels.
My questions are thus:
1. How serious is this?? Am I going to lose a wheel if I don't get it fixed tomorrow?
2. Does anyone think that it might not be the CV joints (or bearings)?
3. Could someone give me a ballpark estimate of what I can expect to pay for this sort of work?
Needless to say, the boys are walking, hitchhiking, and catching the bus now. Maybe they'll rent a car next time.

Thanks in advance to anyone for their insight.
Mike
