Transmission, clutch & driveline
Rear differential fluid change
A drain and fill that rewards doing it before the whine starts. The mechanics are simple; the per-vehicle details are not: fluid spec and friction modifier differ by unit, and the fill plug comes out before the drain plug, which is the classic way this easy job goes wrong.

Each axis is rated 1 to 5 against the catalog's shared difficulty scale. An axis without a rating is unknown, not easy. A time estimate appears only when BuildBay can stand behind one.

Vehicle-specific notes
Where verified data exists for this job, and how far each row is verified. The values themselves (capacities, torque) live in the product, attached to an exact vehicle: an unsourced value never gets printed, and this page prints no values at all.
- Audi · AWDCommunity-verified — confirm for your VIN
If the car has the (optional) sport differential, treat it as its own service — different fluid, own fill points.
- Subaru · AWDCommunity-verified — confirm for your VIN
- Mazda · MX-5 / MiataCommunity-verified — confirm for your VIN
RWD roadster — it has a proper rear diff and a PPF (power-plant frame) tying it to the transmission. LSD cars want the correct friction-modified oil.
- Porsche · Cayenne / Macan / PanameraCommunity-verified — confirm for your VIN
Confirm which differential is actually fitted before buying oil - it varies by trim and option, not by model name.
