Hard to diagnose vehicle noise that sounds like a wheel bearing but isn't, despite extensive troubleshooting.

Noise diagnosis still inconclusive after manual checks and swaps; lacks specialized diagnostic tool for isolating intermittent or transfer case/transmission gear noise.

Workarounds Described

used stethoscope to listen for abnormal noise
test drove and swerved side to side to change loading
drove in tight and slower speed circles
rapid acceleration and deceleration to check load dependence
shook the drive shaft to check carrier bearing

Implied Software Gaps

Vibration analysis tool that correlates noise frequency with speed and load automatically
Guided diagnostic flow that suggests next steps based on test results

App Concept

NoiseSniffer Pro

A mobile app + hardware kit that uses vibration sensors and AI to isolate vehicle noises by frequency, load, and speed. Simply attach sensors to suspect components, drive a pattern, and get a diagnosis. No more guessing or swapping parts blind.

Key Features

Multi-point vibration sensors that sync to phone via Bluetooth
AI-driven frequency analysis comparing noise to known bearing/gear signatures
Guided drive test patterns (swerve, circle, acceleration) with real-time data
Report with likely root cause and repair confidence score

Target Users: DIY car owners and small auto repair shops working on older vehicles (2000-2010) without dealer-level diagnostic tools.

Revenue Model: $149 for hardware kit + $9.99/mo app subscription, or $299 one-time purchase with 1 year of updates.
