For vehicles equipped with a limited-slip differential, using a friction modifier additive is often necessary to maintain the intended traction characteristics during cornering. Understanding its role, composition, and maintenance schedule is essential for any vehicle owner who values performance and longevity.
Rear Differential Oil Cost Savings: Smart Strategies for Extended Performance
Grinding or Clunking: A harsh clunk or grinding sensation during acceleration or deceleration often points to excessive backlash or gear damage. Visible Leaks: Puddles of thick, oily fluid beneath the rear of the vehicle signal a failing seal, which must be addressed immediately to prevent total lubricant loss.
