Thanks for the help, I am removing the passenger side and it doesnt go though the oil pan. Maybe thats the drivers side? I got it all disassembled but I couldnt pull the inner cv joint from the case. Dosent look like there is any special retaining clip on it either.

Oops, I though you were removing the whole assembly. It looks like you need special GM tools. One tool looks like a screwdriver socket adaptor and the second looks like the adaptor.

Any reason why you are doing this? Is something broke? Are you upgrading something?

Thanks for the help. The reason I am doing this is I have a busted outer cv joint and I need to remove the whole shaft to fix it. Thanks for the help.

1) The CV shafts don't touch the transfer case, whcih is attached to the back of the transmission. The front differential is the thing attached to the driver's side of the oil pan.

2) Many other threads discuss the CV shaft removal process, which is basically getting an 18-24" piece of rebar or something similarly long and stout, a 3-5 pound sledge, and whaling away at the bar while the other end is touching the inner CV joint (called the tripot housing) at a slight angle to clear the oil pan. There's a circlip on the inside edge of the splined end of the CV shaft. If you're replacing the shaft, you will already see this on the replacement.

You can also try a pickle fork to pry on it, a flat pry bar (like a Wonderbar), or get an adapter for a slide hammer and take it out by pulling from the outside. Nothing is as potentially quick as the sledge-o-matic and rebar.

cv axles

Would it hurt anything if i removed a cv axle and didnt replace it right away? I have a busted cv axle and dont have the funds right now to replace it but it is the only vehicle i have to drive to work. Any help would be appreciated. I dont really want to mess it up.
