Just because the dust boot is missing, this won't make the noise you discribed. I would have someone move the steering while you crawl under, and get a look at the parts in question. Look for exsessive movement, loose fasteners, or something worn out.




I would also avoid driving the car until the cause is determined. Having the idler arm fail completely would ruin your day, and perhaps the car.

Changing the idler arm is not that big a deal. The proper idler arm puller is available for loan at any Autozone, and the rest of the tools you probably already have. If the idler (and/or any other steering/suspension parts: tie rod ends, control arm bushings, etc.) is shot, the car will probably need an alignment after the new parts are installed.
