Pfadt drop springs, now I have noise?

[monstertodd]

Just had the dealer install my Pfadt sways and springs. I haven't noticed any noise coming from them.

Hey there SSTG, just curious as a troubleshooting step, but do you remember what color upper spring isolators you had installed on your camaro when you took it apart?

Not saying its the source, but there has been a couple of service releases (which I will try to track down for you) for the front struts, and one had an update to the upper spring isolator. They changed from a black rubber piece to a dual material (foam on metal) thicker unit to soften some noise transfer through the struts to the chassis. I will post a pic in a bit, and maybe it will help.

The revised and updated one is on the left, and the older version is on the right.

Is it possible that you have what many people in this thread have:

Just curious, in post #201 by kencarguy (thanks!), he quotes the GM Notice on front suspension noise below:

Document ID: 2512852
#PI0197: Front Suspension Thump or Loose Lumber Noise - (Aug 4, 2010)


Subject:Front Suspension Thump or "Loose Lumber" Noise

Models:2010-2011 Chevrolet Camaro


The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern

Some customers may comment about suspension noise coming from the front of the vehicle when driving at low/moderate speeds (16-40 km/h [10-25 mph]) over rough roadway surfaces (cracks, lightly broken surfaces). The sound has been described as a rattle, knocking, clunking or "loose lumber" noise. This sound should be of a relatively low volume and behave as a brief rumble or thud following impacts with rough roadways. The sound is non-metallic in nature and has a dull wooden character.
The "loose lumber" sound exists as a result of the basic component configuration and tuning that effect the ride, handling and steering of the vehicle.
Recommendation/Instructions

When a customer brings in a vehicle with front suspension noise, upon confirmation of the sound via a test drive, a brief inspection of the front suspension should be conducted (fastener torques, bushing/ball joint health). If no issues are found, the technician should confirm that the sound is/is not typical for the Camaro. (If needed, drive another Camaro and note the sound quality over small impacts.) If the sound is common in character with that of other Camaros, the customer should be informed that the vehicle is operating as intended and that the "loose lumber" sound is a normal suspension sound.
Warranty Information

If the noise is found to be a normal condition, please submit labor operation E9995 (Customer Concern Not Duplicated -- Tires, Wheels, Suspension and Steering); otherwise, utilize the labor operation for the repaired or replaced component.
GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

I think some people may be assuming that they did something wrong in this thread but noticed the noise after upgrading a suspension component. Let me know if this helps at all!

Of course, GM will not exactly warranty any parts that include upgraded springs, and rightfully so. I just figured you may want to read this info in case it applies to you.

[SSTG]

I did a lot of reading last night,including the threads you refer to. I have the old style rubber one. Will the dealer replace mine since the car is lowered now?

[SSTG]

BTW, how do I get my free t-shirt. I posted on your Facebook page

[PfadtRacing]

PM Sent. We will get the shirt out soon!

I have the same problem, as stated above I have heard that rotating the spring slightly will get rid of the noise. I still have to try it. My clunk only happens from time to time and it's not bad at all.
