Awesome that I don't have to completely take apart the wheel... will look at it today.
Would you recommend changing the cups?
What's the best way to test if they are hosed?
The boots were sealed and were in perfect condition, no grit in the grease, there was a little play in them, but real little, and it might have just been total slack down the drive train to the diff.
Would it be worth the effort of dropping the diff?
I got my axle assemblies from O'Reilly (includes the cup). While playing around with it, it surprised the hell outta me that I was able to pull the inner CV right out of the cup by hand (boot still attached). I immediately pushed it back in and felt around for missing balls and didn't find any, so it looks like it went back together ok, but I don't know why they didn't put a retaining ring in their cup to stop that from happenning.
Anyone have any experience with the O'Reilly assembly?
UPDATE - I pulled the boot off the O'Reilly assemby to see if the shaft geometry matched my old inner CV (intending to keep the old bearings since I'm no longer changing the cup), and discovered why it slid out on me earlier. It's not an Rzeppa joint at all, it's a Tripod joint, thus completely a different architecture. The cup is a bit larger than the stock cup, so that should have given me a clue. I put it back together neatly and returned them to O'Reilly. I've ordered the assemblies from Autozone instead (without the cup). I'll let you know how well it matches up to the original stock inner CV geometry when they come in.
