This post is a tiny bit of a cop-out as I didn’t take good pictures of the process, but the fluid change for the front differential might be the easiest job of the fluid changes to do. The drain and fill plugs both use M10 hex heads, and are both located on the driver’s side. This job can be done with the car driven up on ramps, using a jack standard just in case.
The front differential is located where the driver’s side axle goes, and is easy to identify. The fill plug is the plug in the upper right, and the drain plug is at the bottom. Always loosen the fill plug before doing the drain plug, in case you cannot access the drain plug. I used Red Line 75w85 GL5 fluid for the flush.
