Sometimes looking okay doesn’t mean a part is worth reusing. In this Ask the Team video, we asked our mechanics: “What’s a part you always replace even if it looks okay?” They share the components they’d rather replace while they already have things apart than risk having to do the job again later. Knowing what’s worth replacing preventively during a repair can save you time, avoid repeat labor, and help make sure the job is done right the first time. #trq #trqautoparts
