I hear a couple different noises when driving my 2004 Jeep Grand Cherokee special edition 4.0 kind of sounds like exhaust is loose and other noise sounds like it's in between a rattling noise in kind of a knocking noise on front driver side around the tire area

if it is a roaring noise it is probably a wheel bearing going bad

This is a rod going out.

Have a mechanic check lower control arm bushing at the rear of the control arm.It is a horizontal bushing retained by a vertical bolt clamping it to frame.The tire will move more forward and back more than it should during braking. canuck mechanic.

The first thing to check on a rattling noise is if going over minor bumps in the road if that is when it makes noise is a sway bar link, they make a rattling noise. If you raise that wheel up you might also want to try and wobble the wheel to be sure it is not a tie rod end or ball joint. Typically I run into the sway bar links or the sway bar bushings making the noise. However ive even seen it be a rock sitting on the strut plate.
