33 BB driveshaft?
I just noticed that the driveshaft tube on my 33 BB 157" wheelbase has a crack between the front knuckle joint and the next crossmember. Can this be welded or sleeved? Or do I have to pull everything and find a new intermediate tube? Gilda was right "It's always something!"

I don't see any problem with welding it.

Re: 33 BB driveshaft?
I'd like to see a photo of the crack before offering any advice on whether welding it is a good idea.
Is this a shaft or a torque tube? If welding a shaft, it will bow towards the weld when cooling. You can mitigate this by putting a roughly equal amount of weld on the opposite side to equal it up. But not knowing where the crack is, it is impossible to offer good advice. Mart. |

Re: 33 BB driveshaft?
You probably know this anyway . If you remove the bolts holding the big tin cover to the back of the 4 speed you can slide the cover back down the tube . The big U/J is the two piece bolt together style . Take it apart and then you can remove the tube and get to it to weld the crack on your bench . It is fairly thin mild steel and will not distort if MIG welded . When it is apart you can change the seals in the front and rear "cups" .
