    Well hell! Looks like I'm the rusted up category. 2018 GSA with 10,534 miles.
    I've ben trying for three days to get the FD to drop so I could check it...no bueno! So following JVB's tutorial, I figured pull the driveline......well that was easier said than done! The screwdriver popping the circlip as Jim mentioned wasn't working so......
    I ended up getting a pickle fork at my local NAPA for $12.00 did some modifications on it to make it wide enough to fit over the transmission shaft, with a little persuasion, I finally got the driveline to pop!
    Upon inspection the driveline wasn't lubed either!,final drive shaft is rusted. Going to try and post the pictures that I took.
    So the BIG QUESTION whats the best way to separate the final drive from the driveline without screwing up the u joint or damaging the pumpkin? Big shout out to JVB FOR THE TUTORIAL! Thank you sir!

    I was not able to get it off myself, even after cutting the boot off for better access. The dealer was able to separate it, but it took three guys working together to do it.

    Hoping to avoid that, my dealer is 100 miles away!

    @Pendog Yours isn't bad. A wedge shaped chisel between the end of the FD input shaft and the U-joint should easily get it. Just take your time,

    Thanks Jim, what sizeof wedge chisel are we talking about? I would assume that I have to sacrifice the boot?

    They charged me 1/2hr of labor, which was a good thing. My saga starts on page 70.

    Not at all. You can slip the boot off the final drive and the driveshaft. If the FD is still attached, you can push it back.

    The key to the chisel is the same. It needs to be enough to spread the two parts, but not so narrow as to hit the other side of the U-joint or final drive.

    The last two are my preference.

    Thanks, @JimVonBaden , this is gold! Where do you source your thick chisels? I tried all of the local box store and hardware stores but nobody had a chisel like the one in your picture, and my google fu was weak as well.

    Well after breaking two chisels and still no success, I'm again at a stand still. :baldy
    I'm afraid to hit any harder and have it really cost me!
    Would an induction heat unit work? Or will that risk ruining the FD seal on the shaft.
    My "local" dealer (100 miles away) said that it would take them no more than an hour ($100) but would charge less if they got it off quicker. Decisions, decisions

    At this point, if they can safely do it for $100, let them. But make sure you don't pay if they break it.

    You're at the point where I was and said done, and let the dealer separate the pieces.

    2017.5 GS 25,000 miles. First spline lube. Came apart OK, transmission end was a bit reluctant, little heat and PB blaster and it came free. Other than not having much lube left if any, I think the splines look ok. Thoughts from the experts? Going to move to every other year on this going forward.

    Those splines all look great. A little clean up with Scotch Brite, etc. and then properly lubed they"ll be fine for quite a while.
