AV-SCANNER / Service function guides / Steering and suspension
This guide delivers a complete, professional method for inspecting ball joints and suspension bushes across a wide range of passenger vehicles, written for working mechanics and serious DIY owners who need to catch wear before it becomes a failure. It explains how the suspension system loads and articulates each joint, when inspection is triggered by symptoms or mileage, and how to prepare a safe and organised workspace. The step-by-step procedure covers visual checks, load-transfer tests, pry-bar techniques and measurement, followed by result interpretation and vehicle-type variations. After finishing, the reader will be able to perform a structured ball joint and bush inspection, distinguish serviceable wear from condemnation, and document findings for repair or aftercare.
Guidance is general and covers many makes. Exact procedures and values vary by model, so confirm them in the factory service information for your vehicle.
