The differential bearings are then pressed into place on the unit. The Truetrac differential is unique in the fact that it performs like a conventional differential, that is, until there's a loss of traction. Only then will the power transfer occur--when it's needed. The big benefit is that the Truetrac increases traction but doesn't effect steering or wear prematurely, which is a common problem with limited-slip differentials that use clutches and springs.
