You can't, but there is a chest that you can get to by glitching out of Whiterun and following the wall (when you get out you should turn left as most of the right is either going to crash the game or trap you) and then when you see the skyforge from outside the rendered area, go close to the wall and walk through the large rock that is Directly underneath the skyforge. The armor may/may not be there, and the chest will respawn after 2 in game days unless your game is extremely glitched to where the places don't reset.
When you first enter Whiterun, there should be a small room, to the left, in the City Walls you can walk into, you can't miss it. In there should be a wooden Barrel you can't loot. Jump on it, then face the North towards the large opening. Try to back up a bit without falling off the barrel, then speed walk/run and jump onto the largest portion of the crack. Once you are out of the Whiterun map, follow the wall to the left. Do not go to far away, and do not go right as both will either cause a crash. When you see the larger rocks of the skyforge, stick to the wall, and walk towards some of the rocks. There are videos on the internet to show you hands on how to get to it, but when you walk into the rock (It's one of those non-solid mesh rocks), walk a bit further into the invisible pit, and you'll see the chest. Only grab what you need like the gold and armor, and grab a bit less then what your carry wieght is or else you cannot get out of there. After you get what you need, fast travel back to Whiterun or wherever your home is, and then sell the extras.
It should be noted that most people consider this to be cheating, and that if you're going to cheat, you might as well just obtain everything through console using player.additem.
The only ways to obtain the Wolf Armor without cheating is by buying it from Eorlund (who you said died) and looting it from Skjor at the end of The Silver Hand quest. If you are fine with cheating then I suppose you could use console commands if you play on the PC.
