Before fitting replacement parts on a vehicle with major damage, what should a technician do?

Before fitting replacement parts on a vehicle with major damage, it is essential for a technician to take dimension measurements. This step is crucial as it helps establish whether the vehicle's frame and structure are still within specification after the damage has occurred. Accurate measurements allow the technician to identify any misalignments or structural issues that need to be addressed before any new parts are installed.

By assessing dimensions, a technician can ensure that replacement parts will fit properly and that the vehicle's alignment and safety features will function as intended. This process may involve using specialized tools and measuring devices to obtain precise measurements that verify the integrity of the vehicle's structure.

In contrast, simply aligning panels visually may not reveal underlying issues that could compromise repair quality and safety. Repairing minor damages should only be done after ensuring that more significant structural issues are resolved, as minor damage could also be a symptom of more extensive problems. Consulting the owner's manual, while informative, does not address the immediate need to verify the vehicle's structural integrity prior to replacement. Taking dimension measurements effectively lays the foundation for a successful repair process.
