1) will it take out the transmission if it fails like on a DII

2) will (2) 14mm wrench be all i need to remove it

this morning on my way in the vibration got a bit worse and i think it started making noise, like a clicking.

anyway i want to take it back home on my lunch break and get my other car but just incase i want to grab some tools from maintance so if it starts making more noise and vibration i can remove it on the side of the road and drive the rest of the way in diff lock. doubt it will come to that but i like to have the option. i was hoping to get my bonus by now so that i could order my double cardan

From what I've read on D-web I get the impression that front driveshafts seem to fail much more frequently than rear driveshafts (stock). Can anyone explain why that is? Did Rover just under-engineer them? Does the front get more heavily loaded?

Looking at photos of a stock driveshaft next to a Tom Woods the difference is surprising. But the stock rear driveshaft doesn't look that much different from the stock front. So why the difference in failure rates?

14mm yes, (9/16" is equivalent and will work)

No quite..... If those nuts & bolts have been worked over before, you could battle with just 2 x 14's. Rather get your hands on 2 x 9/16's ring/flat combo spanners. Take you a few minutes if you can jack the truck up, otherwise 2 of the nuts on the tranny case side are a bitch to get to ;)

With the open center diff - front driveshaft is loaded exactly as much as the rear. But -
1. Front driveshaft is shorter than the rear -> U-joints work at steeper angles.
2. Front driveshaft's rear U-joint (or CV joint on D2s) is located in close proximity to a catalytic converter. This is the part that fails most often - it needs to be lubricated as frequently as at every oil change, if not more often.
