Where They're Located
Gear oil lubricated differentials are found in two-wheel drive and four-wheel drive pickup trucks and SUVs, as well as rear-wheel-drive passenger cars and vans. Periodic replacement of the gear oil is specified by vehicle manufacturers to maintain the performance and longevity of the differential.
The Problem
Over-extended gear oil service can:
- Lead to gear oil breakdown.
- Cause poor differential performance and operational noise.
- Allow excessive wear and corrosion of gears, especially under severe service driving conditions such as heavy loads, high temperatures and stop-and-go driving.
- Contribute to premature differential failure and replacement (a differential assembly can cost more than $2,000 USD to replace!)
The Solution
Complete replacement of the old differential fluid, in accordance with manufacturer recommended intervals.
Using Wynn’s high-performance synthetic gear oil and state of the art Wynn’s DiffServ™ Differential Fluid Service Machine, the advantages include:
- Helping extend differential component life.
- Superior protection of differential, especially under extreme conditions, including protection against friction, wear and corrosion.
