Bearing swapped. Drone’s still there.
NVH diagnostics locates the actual source of noise and vibration — so you fix the right part, first time.
Sound familiar?
Every workshop has been here. The customer complaint is real, the diagnosis seems right, the part gets swapped — and the noise is still there.
Description
Wheel bearing swapped. Drone hasn’t changed.
Misdiagnosed bearing side is one of the most common NVH errors. The drone continues at speed because the vibration source was never on the side you replaced.
Mounts replaced. Vibration’s still there.
Engine and gearbox mount replacements for vibration are a common speculative fix. When the vibration persists, there’s no obvious next step — just cost already sunk.
Charged for the last fix. Rattle’s still there.
The customer has paid and now expects a free redo. Rattles are the most common vague NVH complaint, and the hardest to pin down without measurement.
Ran every diagnostic. No fault codes. Still runs rough.
Scan tools find electrical faults. They can’t find mechanical ones. When the tool gives you nothing, NVH diagnostics picks up where electronics leave off.
From guesswork to measurement
Every vibration has a frequency. That frequency tells you the source. The software does the matching — you get a straight answer.
1. Measure
Accelerometers and microphones capture vibration and sound data during a road test or static run-up.
2. Identify
The software matches frequencies to vehicle components — wheels, engine orders, propshaft, bearings — and tells you which one is responsible.
3. Confirm
Objective data replaces subjective opinion. Show the customer the measurement, compare against a known-good baseline, and proceed with confidence.
4. Verify
After the repair, re-test with the same setup. The data proves the fix worked — to you and to the customer.
