Re: disconnecting driveshaft for towing 4 down
You'll need a 12 point 12mm wrench to remove the rear shaft bolts off the pinion flange(aka axle side). They're a closed in unit....so there's no straps to deal with. It's all flanged at the back axle and secured with 4 bolts. There's a crossmember above your muffler that's a good place to loop a strap to hold the shaft up. If you're a 2wd, you'll wanna make sure you secure it nicely as the shaft could pull itself out of the transmission and you could have a mess of ATF all over the road. 4wd, that's not a problem as the shaft's slip is in the shaft as opposed to the slip being at the trans on 2wd's.
BUT....if you're a manual trans, just leave it in neutral.
What you've read about taping is probably marking the location of the shaft flange to the axle flange. Put it back in the same orientation when you bolt it all back up.
