Possible causes for rattle in front end

Recently I've noticed a rattle in my passenger side front end. It happens when I hit uneven pavement when going 20+mph. It sounds as if something is loose but I can't pinpoint where. Not a loud clunk...more like a loose rattle.

Not sure if that's enough info but this forum has worked wonders before. Thanks all!

Most suspension parts result in a clunk type noise unless a bushing is totally blown out or the part is badly worn or very loose which should be easy to spot by grabbing or pulling on related parts. Do a steering check. Check all control arms. Make sure shocks are tight. Jack it up and let the suspension hang, sometimes that reveals things too. Does the noise stop with brake application? If it does check brake system. Check under the hood as well for anything loose. With the hood closed the sound will seem like it's coming from underneath. Rattles can be a pita to track down when you can't duplicate the driving condition while being underneath to look. Good luck.

Ugh!! Mine had some bad rattling from slightly under tightened sway bar link bolts. I have one minor low pitched rattle or jiggle still.

Should the control arm bushings be solid or squishy (like be squishy when the control arm is moved with a pry bar?)

Have someone bounce on the bumper while you look. I'd start with the sway bar links.

OEM Clevite bushings are solid rubber, however, "squishy" is a relative term. Use a big enough pry bar and apply enough force and they will move.

If they appear cracked or dry rotted it's probably time to upgrade.
