Tap the companion flange (the part the driveshaft bolts to on the rear axle) with a mallet or hammer (not the shaft itself of course). You may need to pry it a bit too to free it.

gtford86:

The bolts are held in with red Loctite so a little heat will help to loosen this stuff. Use a propane torch with a small flame. When it is warm, get the 12-point wrench on the bolt (and you might need an extension on the wrench for leverage). Repeat for each bolt.

HTH,

I literally put my foot into mine. Attached a 12 point wrench and used slow, even pressure to break them loose.

I think he said the bolts are out.try tapping a screwdriver between the pinion flange and the yolk flange.you may have to move the driveshaft back into the tranny a hair.also make a scribe mark on the flanges,so you get the correct orientation during reassembly.

rockyracoon,

Good eyeballs, brother! Yes, the OP does say he has the bolts out. That's a good tip about marking the two flanges, too. (You're doing a good job dispensing help, lol.)

So, what about some PB Blaster to loosen up the rust/corrosion products between the flanges? Once it has worked for 10 or 15 minutes, you can then tap in a thin metal spackle trowel in between the flanges. Gentle taps to ease the flanges apart and don't let the driveshaft drop onto the garage floor (put a cardboard box or some other cushion under it).

HTH,

Chris

After letting mine soak with KB88 for a couple minutes, I just gave mine a thwack with a ball pean (pean, pene wait wut?) hammer at the base and down she came. Twas deceiving though, for a second I thought I missed a bolt, turns out it was just stuck.

Its a tough piece so I didn't really worry about hitting it. Not like I hammered the hell out of it, but did give it a good....thwack.

 

[COramprat]

OK...I see that now. A good whack with a hammer on a block of wood on the flange should do the trick.

That's how I got mine out.

And yah dont let it hit the floor when it drops out.

G'luck.

When doing this mod, is the driveshaft the only upgrade thats needed?

Putting a new driveshaft in isn't needed when changing gears, but an aluminum one is a great idea!

Actually it is one of the best idea's. There have been a ton of people with vibration issues when going to a 4.10 or higher without the aluminum DS. I would never go to that gear without a good DS in place.
