To break it in and also to test and be sure that it can withstand a load.
A rear axle adjustment is also known as a rear axle alignment. The perimeter chassis of the car needs to be measured before a rear alignment is performed.
Preload refers to the initial tension applied to the rear suspension components, particularly in relation to the axle, before any load is applied. It affects the ride height and handling characteristics of the vehicle by determining how much the suspension compresses under weight. Adjusting preload can help optimize traction and stability, ensuring that the vehicle performs effectively under various driving conditions. Proper preload settings are essential for achieving the desired balance between comfort and performance.
Preload is the amount the pinion bearings are squeezed together by the pinion nut.

I had new tires installed by Firestone on my 99 Cobra and a axle on the left rear where I had excessive wear on the tire. After the installation I was told they could not align the left rear because there was not adjustment available. They contacted Ford and told me the adjustment could only be done by Ford. Apparently from what I have read there is no adjustment to the rear on the Cobra and the front is suppose to be aligned to the rear. I am going to call Ford and get their take.
