this was done on my 04 G35X with 80K miles.
I took off my compression rods to change the compression rod bushings with ER bushngs.
I also removed my upper A arms to replace them with SPC upper A arms.
I removed my brakes rotors and pads to add new OEM pads and rotors.
Finally I removed my struts to change out my springs to H&R's and new Monroe struts.
So all that being said I had a lot taken apart already so I fugured I'd tackle my CV shaft at the same time to replace the boot that just went out a few days ago. My CV shafts are not clicking or making any other noises so I beleive re packing them and putting on new boots should keep them going for another 80K miles.
Since I had so much taken apart I can't say exaclty what the least amount of parts to be removed would be in order to pull the spindle back in a fashion to do this. I saw it on another thread though that I will add the link to shortly.
I got a Nissan boot kit from the dealer for $20 only to replace my passenger side inner boot. It comes with new grease and the clamps. After removing it I paid a shop $50 to replace the boot since I didn't have the tools to use on those clamps that hold it on and I wanted to be sure they disassembled and reassembled it propery. So I'm out $70 to replace the boot.
First this is what we are removing.
you need to be able to pull the spindle outward like this from the top
while I pulled the spindle back with one hand at the top I used a mini sledge to tap the CV shaft straight back out of the wheel hub. Make sure you have the nut on and only tap on the nut so you don't damage the shaft threads. Mine was lightly rusted in threre but the axel shaft on other side just fell out of the spindle. (The shaft joints stretch the shaft outward out so you're not hammering it into the differential)
this is what you will have
big greasy mess from the boot letting go it was coiming out all over my rim even.
the shaft still installed and you can see where I have a tire iron run through there prepared to pry it out.
close up of my pry spot and really with the flat potrion of the tire iron I just twisted the tire iron with the flat part wedged in there and it came right out. They're not in there that hard. No fluid came out of the front differential.
CV shaft removed - where and how I pryed it out....
CV shaft removed
I took the shaft to a shop and had them put on the new boot.
Reassembly is simple.
Push the shaft back into the transfer case. I just jabbed it in there with my hands and it clicked right back in. I tugged on it and it wouldn't come back out so it's in. My shaft where it ran through the spindle was a little rusty so before putting it back together I sprayed PB blaster all over it and inside the wheel hub and scrubbed the axel threads with an old toothbrush. I sprayed and wiped until the threads were pretty clean then I put on some grease and it went right back together by grabbing the top of the spindle and pushing in after it was started and the CV shaft was already in the transfer case.
