Subaru Legacy Differential

The drivetrain component called Differential in Subaru Legacy vehicles lets drive wheels move at different speeds because this function enables precise cornering and surface traction control. The different Subaru Legacy models implement two primary Differential options starting with an open Differential followed by limited-slip Differentials (LSD). When the open Differential equally shares torque to both wheels it results in decreased traction during slippery road conditions. The LSD achieves better performance through its mechanism which distributes torque unevenly to the wheel with better traction yet struggles to start moving on slippery roads. Since its inception Subaru has implemented different types of Differential mechanisms starting with bevel and active system parts to optimize handling and torque transmission. Better traction performance emerges from the LSD system although different types of replacement units offer specific benefits and specific drawbacks during challenging road conditions. Optimal Legacy replacement part performance depends on regular maintenance because improper care results in operational problems and expensive maintenance costs.
