Deceleration Noise
First of all, I originally posted this in the SRT-6 forum by mistake. So I am trying again.
I own a 2005 Crossfire Roadster with about 42000 miles that I bought in 2008 off a lease.
It has recently begun making a "noise" when decelerating at slow speeds: 5-35. It may make the noise at higher speeds but I'm probably too deaf to hear it. It is not a whine or a grinding noise. Sort of sounds like a bearing somewhere like in the alternator or maybe that air pump. If I am in park and rev the engine there is no noise. Have to be driving it. Does not matter if it is automatic or paddle shift mode.
Any ideas before I have to visit the dealer.
VIN 1C3AN65L85X040101
Year 2005 Engine Type 3.2L V6 SOHC 18V
Trim Level Roadster Limited Front Brake Type Disc
5-Speed Automatic Overdrive

Dealer should be last resort. Check this post out : https://www.crossfireforum.org/forum...tml#post775124

Re: Deceleration Noise
Thanks for the quick reply. Will read all the posts and replies carefully and start my investigation However, I would think that since the "noise" only occurs when driving (not in park when you rev the engine) it does not involve any of the pulleys but I imagine anything is possible.

Re: Deceleration Noise
Does it change of the brakes are on of off ? If there when braking first thing I would do is check the rotors for scoring and brake pads for wear. Also I would check the differential fluid (not that I suspect it but a good time to check since I'd raise the car and remove the wheels to reall check the brakes.
If not the brakes, does it change if going around a corner ? Left and right or just one ? (If so I'd suspect a wheel bearing).
Let's start there.

Re: Deceleration Noise
I say brakes because they can rub all the time if you have a sticky caliper and the noise may only be evident when you slow down and hear it.
You say a smell, so look for odd rotor wear and excessively hot rotors after a short drive.

Re: Deceleration Noise
Agree with one caveat: if a front caliper sticks you will generally get a pull in the steering. Rear might not. This is where one of those $20 (have seen for $10) IR temperature gauges from HF (I prefer the gun but these will work) are very handy for a quick stop and check of all four. Also good to find a misfiring cyl.
That said I would not be surprised to find a darkened surface on the rotor if a brake is dragging.
Also if just happening on decel without braking I'd also check the caliper bolts (18mm socket AFAIR) on all four. You really really REALLY do not want a caliper coming loose (punched a hole in an aluminum rim that way once upon a time).

Re: Deceleration Noise
I do believe you may have it here. I had noises when my front tires developed a bad saw tooth wear pattern on the edges of the tread. I only heard the noise slowing down. The worse the wear got the higher the speed became when I could hear it.
I had forgot about that entirely.

Re: Deceleration Noise
Cardone are a big supplier of rebuilt parts and they are OK as far as I know.

Re: Deceleration Noise
OK
My approach is one thing at a time, not shotgun as you suggest. There is definitely a front caliper problem. Since it is the most obvious, I will take care of that first and then see if the noise persists. If the noise persists then I'll work on a solution for that based on what has been suggested.
for now, things on hold till brakes fixed.
Sorry if I missed some rule about either closing down a thread or suspending it. Have no idea how to do that anyway.

Re: Deceleration Noise
Haven't seen this as an issue here.. don't know that it "could" apply.. But the rubber brake line/connectors on my 94 Silverado had actually swollen shut.. fluid under pressure could pass through.. but pressure release was a very slow process. Discovered this as the problem after replacing a caliper.

A mod could move it if they saw it was in the wrong place or you could ask them to move it, but it is too late now though.
You say there is a problem, what is it? If people are to help then you should say what the problem is and not just leave them hanging or you may find you are ignored. Do you get my drift? People like to learn new problems.

Re: Deceleration Noise
The presenting problem is a sticking caliper piston. I'm not going to waste time trying to clean and polish the piston and cylinder. I'd rather be driving so I'm just going to replace both front calipers with rebuilds and go from there.
