I have a chrysler 300, 2005 model with 3.5 liter V6. I have a noise in the front end when going over small bumps like something is loose. A metel noise. Dealer has replaced 4 tie rod end and lower control arms , but the minor noise contuinues. I'm being told to replace the link pins from the sway bar to get rid of it. Does this make since ? Thanks for any help

Wind......yes, only if something is loose and swinging around. Check the stabilizers as they often cause a clunking sound and is more pronounced when going over bumps, even small ones.

Get it up on a ramp , Clank / Knocking can come from anything underneath , SILENCER, EXAHUST PIPES. If the clanking happened since your repair , and not before , take it back to the Garage / Workshop and tell them about the problem

It sounds as though something is loose, probably in the front end. Check, or have a shop check the front end components or for any loose body parts that could be causing the nose. I hope this helps.

If it's a knocking noise, it's either a swaybar link or a control arm bushing. Because you said "also while turning" I'd have to lean towards the control arm bushings. If it's another noise, you'll have to describe it more accurately... Your model car is notorious for front-end issues, among other things.

if the popping sound occurs when going over bumps, you may want to have the stabilizer links checked for looseness.

Where was the flat? If the flat was on the Front end, the Spare may be bad or the Lugbolts are loose. If the front hit something hard enough to blow a tire, there could be related front damage. But a nail would not damage the frontend, just the tire.

You should check the E brakeshoes, but really there is a possibility the E brakes would have messed up once they were used. The parts back there could be rusty anyway and would not reset if the E brakes were off. Sounds like the neighbor did a favor and did right by setting the E brake when jacking the Vehicle.

There may be extra noise if the Spare was hung back under the vehicle. As the tire is flat it will not tuck in tight without air in it.

It could be a couple of things.
Loose or worn out strut - (jack up car, remove tire and shake the strut really hard to see if it's loose. Check for signs of leaking or damage to strut)
Missing rubber isolator under front spring (visually inspect the suspension while tire is off).
Broken sway bar mount or missing rubber in the mount on the frame. (Lay under the front and look for where the sway bar mounts to the frame. Make sure everything is tight and the rubber is still in it.

Shocks is most likel by they the culpret./ Or a loose heat sheld by the exaust

The LX platform consists of the 300, charger and magnum.

They will all have front end noise. It's just a matter of time. This appears to be a poor design and should be recalled.

The front end should be replaced with energy suspension bushings and greasable ball joints.

The front end needs to be inspected, but here are the usual suspects. Most to least

1. Stabilizer bushings to frame. Rattle and bump sound. Not too expensive.
2. Tension struts - radius arm as some may say. Makes a poping noise and moans when driving and turning.
3. Stabilizer end links if loose to touch. Noise over bumps only.
4. Tie rods. Primarily outer. If you can turn them by hand they need changing. These make noise when braking and turning. Inner is more pronounced when steering. May cause road wander.
5. Upper and lower control arm bushings. Creak!
6. Ball Joints. These sound like an orchestra when going up a driveway. The most expensive fix on these cars. Up to 1800.00 dealer cost. They do not press out the old joints. They use a new knuckle.
7. Steering rack... another expensive fix. Moans and hisses.

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.
