Working safely is always of paramount importance.
Always chock both wheels on the side of the vehicle opposite to the wheel you’re working on. But beware – if your garage floor is especially smooth or painted, the chocks may slip. In this case, position rubber matting under the wheels and chocks. Never place any part of your body under the jacked-up vehicle unless you have the necessary safety stands in place.
Park your car in your garage and hide your ignition key away in the house. I’ve mentioned this before, but believe me when I say people have been seriously injured, or worse, when a hurried family member jumps into the driver’s seat, starts the engine and drives away while work is in progress.
Leave the gearbox in neutral and the handbrake off ( this is why we use wheel chocks), as you will need to manually spin the wheels.
