I have a 2003 Alero, 2.2 liter, 80,000 miles. There is a noise which appears to be from the front, best described as a "rumble" or "rattle". Most prevalent on rough roads, but always noticable. Have replaced both front struts, strut bearings and both front wheel bearings, noise still there.
Thank you,

i have the same problem on my 04 alero 3.4 liter with 75k on it. i just turn up the radio to get rid of the noise.

This is most likely a bad tire rods or front hub assembly
