Help!

I don't know if this will sound dumb or not. Here's my question. I had read somewhere that newer cars do not need tune ups because they are all computerized. Is this true?
Also, my front end seems to be making a grinding-type sound, like metal rubbing against metal. I know I am due to have my front brakes replaced, but that's not where the noise is coming from, because I hear it when I'm not even touching the brakes. Can anyone out there help me, and maybe perhaps give me an idea on what that will cost me to have it fixed?

yes there are certain intervals to which certain things need to be performed.. Your computer has nothing really to do with it, its just keeps things running properly. Like some of them require a tranny flush and refill, coolant flush, power steering service... you get the jist of that... that scraping noise can be almost anything... try gettin a better idea where its comming from.

It's coming from the wheels area, I hear it when I'm going down the road, and when I'm turning. It sounds like metal rubbing against metal.

well...Brakes have a little plate on the outter edge of them that will start scrapping on your rotors when they get to a certain amount left. Also not having yout sliders lubed will causes problems.. only other thing that can rub is your wheel bearing being shot... but that is more like a humming noise..

I would venture a guess that it's your CV axles/joints. My car made a noise very similar to what you described. First only when turning, then always.
The best way to check is to get under your car. There are two CV boots on each axle, and the boots protect the CV joints.
They're not the cheapest to replace, but the good news is that if you have the time and the equipment, you can replace the CV axles yourself. I replaced my own using only a good set of jack stands, some normal shop tools, and the Chilton manual.
Make sure to ask the parts store if they'll take the old ones back so that you can get your core deposit. The core deposit is a fair chunk of the price of the CV axles.
Anyone else think I'm on the right page here?
