Looking at that picture, I will say you may have a little problem getting the cone washers out. I would take the nuts and washers off, soak the area with good penetrating oil like PB Blaster, and let it sit soaking over night. Then I take a brass drift and hammer and hit the studs with the drift and hammer this will break them loose. Find the split in the cone washer and I use a small, thin blade screwdriver and tap it into the split and they usually come right out. I would get the rebuild kit and replace everything.
