Can't see 03 being way different from older independent front end trucks from GM or Dodge. Pulled a bunch out when working at chev and a trans shop. Was many times easiest to drain fluids, pull shafts etc and remove 5 or 6 bolts/nuts and pop case out of there first. That also made it easier to access the trans to eng bolts too. Many could be loosened, slid back a few inches, and nose tipped down to drop forward away from torsion bar cross member. You WILL probably drip some oil on your face or arms. I was doing alum case removal by hand alone then, would not try lately.
