HELP I cannot get the half shaft out

So the day I bought our commander I noticed it a clunking in the suspension. The next day when I glanced under the truck to see what might be causing it I noticed I was getting a bit of grease tossed out onto the truck.

Upon further inspection I found that the outer CV boot had torn right where it meets the metal edge. I now have lots of grease thrown out and have started to develop fun noises when I let off the gas on that side and tire, so I ordered a re-manufactured one in.

I'm now getting ready to replace both the lower control arm and half shaft on that side (bushings appear to be shot as well), and am looking for any tips and/or suggestions.

I've worked on CV shafts before, had to replace 4 or 5 over the years, but wanted to make sure I don't miss anything special on the commander.

Do I need to keep the side I'm pulling the shaft from elevated to prevent pouring out the front differential fluid?

Anyone know what size of socket I'll need to pull the nut off the threaded end of the half shaft?

Any other items to pay special attention to?

HELP I cannot get the half shaft to come out of the front differential, how are you supposed to remove it? Pry bars or a slide hammer?

Well I will attempt to give you some help. To your first question, what is the size socket you would need to remove the nut from the axle shafts....It is 1 3/8" or 35 MM. You should only have to gently pry on the axle shafts to remove them from the differential. If you get on the superlift.com website, read the directions for disassembly/installation of the 4in lift, that will tell you what you need to do and list all the torques required for reassembly.

The socket I used was a 36 mm (had to call the dealer and ask), and the half shaft will not come out easily or otherwise. I'm starting to think I might have to open the diff to find out what's going on.

No instructions on the superlift site.

I've disassembled everything according to the instructions, but the half shaft will not pry out of the differential. It seems to be fastened in somehow.

I can't think of a thing on your Commander that would use ball bearings that small.

PS.....To me, they look like front bearing balls from a bicycle or the balls from a front fork pivot....bicycle or small motor scooter....something that uses uncaged bearings.
