Axle Flange

[BigSky]

When performing a cv service I discovered that a couple of the bolts were only finger tight. They were all missing the serrated lock washers. When cleaning up I noticed one of the axle flanges was bunged up on the outside lip. A couple of the bolt holes look a little rounded out too, but a bolt still threads in ok. I'm thinking I should just find a replacement though.

Is an Autostick flange the same as a manual. I'm assuming so. I may just go ahead and replace the axle flange oil seals as well. Is it necessary to drain the gearbox to do this? Thanks in advance.
