I would still get the cheaper ones. However, I would stay away from the annular ones if I did. If all I could get were annular, I'd go with the more expensive axle.



That aside, its actually not that bad a job. (Now that I've done it 3 times.)

1) Losen lugs on tire.
2) Chock front wheels, remove parking brake.
3) Jack up rear end (put on stands)
4) Remove tire
5) Remove fill plug on diff, then remove drain plug. (fill plug first just in case it won't come off.) (17mm hex)
6) Pleace jack under diff.
7) Remove diff mount bolts from frame (4 12mm)
8) Lower diff
9) Remove diff cover. (8 15mm bolts)
10) Pull snap ring.
11) Remove wheel side axle bolt. (12mm on mine)
12) Raise diff with jack all the way up.
13) Remove axle from wheel side first
14) Pull axle from diff.

reverse for assembly.

I think I've got it down to about an hour labor now if I have all the needed tools/stands/etc onhand before I start. To be honest I find valve adjustments to be more of a pain.
