Mobile Differential Fluid Exchange — Medford, OR

$99 per differential, in your driveway!

This One Gets Skipped More Than Almost Anything Else

Differential fluid doesn't make it onto the quick-lube reminder sticker. It's not something a lot of shops bring up unprompted. But inside that axle housing, gear oil is keeping the ring, pinion, and spider gears lubricated and when that oil breaks down or gets contaminated, those gears start wearing faster than they should.

The differential is what lets your wheels spin at different speeds when you corner. Without proper lubrication, you accelerate wear on precision components that are expensive to replace. Most manufacturers call for a differential fluid exchange every 30,000 to 50,000 miles — less if you tow, go off-road, or drive in extreme heat or cold.

We drain the old fluid and actually look at it before we dispose of it. Metal shavings in the oil tell us something important about what's happening inside. Then we refill with the correct gear oil to spec

Frequently Asked Questions

Q: How do I know if I have a front differential, rear, or both? A: Depends on your drivetrain. RWD vehicles have a rear differential. AWD and 4WD vehicles typically have both, and some have a center differential too. We'll identify exactly what your vehicle has before we arrive.

Q: My vehicle has a limited-slip differential — does that change anything? A: Yes. Limited-slip differentials require a specific friction modifier additive in the gear oil. Using standard gear oil without it will damage the clutch packs. We always check for this and use the correct fluid.

Q: How often should differential fluid be changed if I tow? A: Towing generates extra heat and puts additional stress on drivetrain components. We recommend every 15,000 to 30,000 miles for vehicles that tow regularly, potentially more often if you're towing near your vehicle's max capacity

Q: Do you cover White City and North Central Point? A: Yes, White City, North Central Point, and the full 15-mile radius around Medford are in our regular service zone.
