Background
The test track is designed to provide the desired input
energy (frequency range and amplitude) to excite specific
squeak & rattle concerns (based on benchmarking Volvo,
NA Plants, and DPG) .




Interior squeaks & rattles
Body Creaks
Chassis Clunk / pop / other noise
Loose stock
The surface lengths are optimized to allow sufficient time for the
track to excite concerns and for the driver to recognize and locate
the source.
The S&R test track should be covered to eliminate effect of snow,
rain, ice (provides a consistent environment)

Current Status
The Best Practice S&R test track has been installed at the
following plants (enclosure is not included)
 OAP in July, 2001 (funded by facility/new launch f
 KTP in July, 2001/May, 2002 (funded by PVT / 2002
FAE Quality Budget)
 DTP in June, 2003 (funded by facility/new launch)
Requested funding to implement the Best Practices S&R
test track for the following plants (request was rejected):
 LVL & KCAP-SUV (2002 & 2003 Quality Budget)
 LVL (U251 program)
 Strategy to implement 2 plants per year (5 year
migration plan)

Other steps to Improve S&R Process
• S&R QOS
• NOMAD (S&R objective measurement to
validate product/process changes)
• Formal training (includes a training video
tape)
• Provide a reflective sound walls
• S&R test track minor Modifications and
continuous coaching as required.
• Speed signs / Visual Aids as required.
