brakes and rotors will not cause noise unless they are badly worn and this will be evident on inspection
most noise will be from rubber suspension bushes and sway bar and shocky rubbers
I would suggest that you get quotes from suspension accredited shops and have each shop show you what is worn and what is ok
ON good roads ( hard surface) suspension units should last 60.000 miles before requiring repairs ( barring road damage)
sway bar bushing could be problem. I would replace it before trying anything else and yes that will cause it to pop from time to time. In some cases if not replaced in time the bar itself could break
First,as you travel over a rough road that causes the rattle apply the brakes slightly,is the rattle gone now?If so it's loosely mounted brake pads and/or worn brake caliper mounting bolts/sliders.
Rattle still there with your foot on the brake?Then it's usually the sway bar links and/or sway bar bushings.
To check this sway bar noise,disconnect the sway bar links and tie the bar up/out of the way and try that same road.
No noise now? address sway bar bushings and/or links.
Still noise?Might be struts.
If someone tells you,.you have loose lower control arm bushings,have them show you the play in the bushings before you spend any $$$.
That is a picture of a Porsche sway bar, but the idea is the same. Make sure all bolts are tight and that one end is not missing the linkage that connects it to the spring/strut. The grinding of the brakes may be the sound of the linkage piece touching the rotor. Sway bar is a logical solution to both issues.
If that doesn't fix the issue, put the front end of the truck on blocks or jack stands and have somebody wiggle the tire up/down and side to side while you inspect the mechanical components underneath. Other things to check may be the ball joints, tie rod ends and suspension bits.
I had the same problem with my 2002 Town and Country Limited. I took it to the mechanic and had the sway bar links and ball joints replaced and still had the same clunking noise when going over bumps at low speeds. The van sounded great on the highway, but country roads were horrible. I was about to replace the struts and pay another 700 dollars when i read somewhere that the sway bar bushings could wear and cause the noise. I took it to the mechanic and he said absolutely not it would be a waste of money. Being the stubborn guy I am, I went to NAPA and bought the two bushings for 12 dollars and replaced them myself in an hour. I took the van for a test ride and the noise is completely gone. Please ignore your mechanic and replace the bushings ASAP! Pretty cheap try even if it doesn't work.
you must replace and lube the front sway bar bushings,chrysler service bulletin calls it a squak, but can sound like a rubbing, a clunk etc the common factor is this is really noticeable the colder it gets outside
