I had to swap an axle on a blazer that did the same thing, only he snapped the flange right off the axle shaft, and we had to rebuild the drum brake system on that side. Its a fairly simple fix that you can do in your garage with the proper tools and knowhow. ]
Disassemble drum brake
Open diff. Cover (you'll need a new seal for this, and a grinder to clean all the old sealent off)
Remove "C" clip
Slide axle shaft out (good time to replace bearings too. We had to on the blazer cause the damage was so bad)
make sure new axleshaft is clean, and greased(with proper axle grease) insert to axle.
Diff. cover back on
Fill Diff with proper Diff fluid and level
Drum brake assembly back together.
Check all nuts, bolts, and joints for leaks.
Test drive to make sure its all together correctly. If you look in your rearview, and see a skinny pole attached to a tire, and your truck suddenly dips to the back corner, you did it wrong lol. (highly unlikely, you have to be retarded to not notice what would cause that before you drove it)
