Why Harmony drivers book mobile differential & transfer case service
Harmony is small-town Iredell, and the nearest full-service shop is a real drive. Bringing the mechanic to you makes more sense out here than almost anywhere. For differential & transfer case service, that means no tow, no ride-share to a shop, and no day off work — we do the job on site and you get your keys back the same visit.
What's included
If you tow, haul, or drive an AWD vehicle, the differentials and transfer case are working hard and their gear oil needs to be changed on schedule. Whining from the rear at speed or a clunk on takeoff are signs it's overdue. We drain, inspect the oil for metal, and refill with the correct weight and limited-slip additive where required.
- Drain and inspect old fluid for metal or water
- Replace the cover gasket or drain plug crush washer
- Refill with the correct gear oil and friction modifier if limited-slip
- Check pinion and axle seals for leaks
Signs it's time
- Whining from the rear at highway speed
- Clunk on takeoff or when shifting
- Fluid leak at the axle or pinion seal
- You tow or drive gravel regularly
- Past the interval
