Trucking & LogisticsVehicle Mechanical Issues4HighOwner-Operator or Fleet Driver$ explicit

A truck's rear axle has a skipping/hopping symptom when turning that persists despite tire replacement, alignment, and dealer inspection, with one wheel binding when spun by hand, and the dealer says nothing is wrong.

The dealer can't diagnose the root cause and dismisses the issue, leaving the driver to consider costly exploratory disassembly without a clear diagnosis.

Workarounds Described

spinning rear wheels by hand and comparing resistance
removing differential cover to inspect for metal particles
relying on dealer opinion despite persistent symptom

Implied Software Gaps

Automated wheel spin resistance measurement using phone sensors
Diagnostic guidance that doesn't require opening the differential
A platform to aggregate similar cases and known fixes

App Concept

AxleAnalyser Pro

AxleAnalyser Pro is a mobile app that guides truck owners through a structured differential diagnostics workflow, uses torque and rotation sensors (phone accelerometer and video) to quantify wheel binding, and provides a probable cause report. It bridges the gap between driver observations and dealer certainty, saving costly guesswork.

Key Features

Structured symptom checklist with video recording of wheel spin resistance
Angular velocity measurement via phone camera to compare wheel free spin
Probability engine matching patterns to known differential failures
Step-by-step inspection guide with annotated diagrams
Report export for dealer or third-party mechanic

Target Users: Owner-operators and fleet maintenance managers in the trucking industry who maintain Class 8 tractors (especially Freightliner Cascadia models) and face undiagnosed drivetrain issues.

Revenue Model: $19.99 per diagnostic report or $9.99/month subscription for unlimited reports and access to a community case database
