Claims (16)

1. A support structure for a differential assembly comprising:

a support ring having a peripheral wall extending between a first face and a second face, the support ring having a non-hollow body;

a bore in the peripheral wall sized and shaped to receive a pinion shaft;

a first aperture in the first face and a second aperture in the second face, the second aperture in fluid communication with the first aperture; and

wherein the first face is recessed into the support ring.
