Squeaks and rattles should never be ignored. Some causes can be relatively minor but some can lead to serious safety issues. The best place to start is with a steering and suspension systems inspection at a tire and alignment shop.
There is a tool you might be able to borrow or rent from an auto parts store that borrows them called the "Chassis Ear". It is a set of six microphones, a switch box, and headphones. You clip the microphones to suspect points, then drive around while listening with the headphones. You can move the microphones around to zero in on the source of the noise. Be aware that many mechanics have never seen or even heard of this tool. Suspension and alignment mechanics use it to find rattles, squeaks, and other noises.
