Tucker, place a big plastic sheet under the car, or drive the car onto it, then start your oil works. Its good at catching the odd nut or bolt that drops too, then when finished, roll the sheet up - job done.
Forgot to mention what I did today
Tracing a rattle from r/o/s hub to a bit of grit which has managed to find its way into the hub cap. Wheel off tomorrow to cure it.
