I would recommend an Orangewood stick as opposed to a small screwdriver. Much easier on the surfaces.Watched David (the GT with the trailer) do this at Dearborn. With the forged wheels, just pop the center cap off with a small flat screwdriver. One of the items he keeps in the trailer is the biggest torque wrench I've ever seen.
I probably should have stated I have approx 12K miles on my car, never had any work done on the axles other than Ford replacing the interior axle bolts as part of the TSB and no hard burnout history. The car has been tracked multiple times however I would have thought it logical for the suspension designers to have dialed that into the design.Thanks for the heads up. Curious what the rough mileage of the two cars are.
