Weird loose rattle sound over bumps in the front end???? (Moved)

[SRT_3Hundy]

Hey fellas,
Ive had my car for about 2 months now and i feel like there is something loose in the front end so im posting this up. Its an 06 SRT8 300C and only has 16,000 miles on it. Its due for brakes which seems normal for the SRT's around the 15,000 mile mark and im about to order the posi quiet pads for it. I need something quiet with good performance that will cut down on the brake dust so i figure thats my answer.

Anyway, back to the front end.... I had the car in at the dealer to check it out under warranty. They replaced the strut tension bars and said it was fixed. Well, ive had the car back now for 2 weeks and that same feel is still there when i hit abrupt bumps in the road. It feel like something maybe tie rod or ball joint related? Anyone else experience this???

Im not sure if im just crazy and being too picky with the car but its been bothering me and im considering taking it to another dealer to get another opinion. Other than this, the car has been great! I forget how fast she is when im just cruising around but when i let her rip... she flys!!! Im loving it!!!!

Thanks for the help guys!!

My 05 300C has loose rattle from left front, only audible at low speed especially over speed bumps. You'd think it would be sway bar links/rubbers or brake pad separation, but it isn't. Front end is tight ie tie rod ends/ball joints, car runs straight/ no uneven tire wear. A puzzler, I'm still looking!!

I believe thats what they replaced on mine. The strut tensioner/stabilizer bars or whatever.

Mine has yet to wear the tires in any odd way and when i take corners, it seems to handle like it should. Its just over abrupt/sudden bumps that you can feel/hear it. The dealer couldnt find it and neither could I. Im sure there is something we must be missing though....

Drop the pressure by 5 pounds in your tires and take it for a another run over the same road that causes the bumps and the noise will go away.

I find that overinflating the tires is the main culprit.

Try it.

Could it be the engine bouncing against its mounts?

I have a 3.5 with the same noise.Brought the car in last week and my mechnic told me I needed all tire rods replaced and 2 torsion bars also replaced.So i asked him will the noise go away and he said yes.Guess what the noise is back a week later and $500 short in my pocket.Going to bring the car back after the snow ends.Just snowed in NY.I will give a update once I talk to him.I just hope they dont keep telling me to replace parts and the noise is still there.

[frankieo]

vinster please post update when you get the car back. let us know what they tell you it seams like everybodys shop says its something else but it looks like nobody figured it out yet where that noise come s from.

What tire pressure do yall run in your tires? Im running 35 indicated on the cluster but when i check it with a manual guage at the stem, its actually around 38-39 PSI. Im running on the SRT 20's if it makes a difference from the 18's the other C's come with...

Ill try lowering it a bit and see what happens. Im planning to take it to another dealer soon though to have it looked at again by some new eyes...
