1. Battery reserve
Weak starts and short-trip battery complaints
Record use pattern, battery age, test result, and charging result before drawing a conclusion about the charging system.
2. Brake refinement
Rear brake squeak and weather-sensitive brake noise
Separate noise from a change in braking performance, and have pad material, rotor surface, hardware, and warning lights inspected.
3. Front-end refinement
Front clunks over driveways or bumps
Record the surface, steering angle, speed, and location of the sound; inspect visible links, bushings, tire condition, and play before quoting work.
4. Rear-end noises
Rear suspension noise over bumps
Inspect the exact source and visible components before assigning the noise to a larger suspension repair.
5. Highway refinement
Tire and wheel issues that get blamed on the wrong parts
Record tire condition, balance history, wheel damage, pressure, and the speed range before a wheel-bearing or suspension diagnosis is considered.
