Welding rear pinion yoke ?!?

What is the stock yoke on the D35c made of: cast, nodular, forged? Both u-joint retaining tabs on my buddy's stock yoke broke off so I welded a couple of short beads in the inside arch of the yoke to hold the caps in place (probably for life [img]/wwwthreads_images/icons/laugh.gif[/img]) with the u-joint installed. It seems to be made of cast iron. I used a wire feed welder with flux core wire. The beads looked fine but I wonder about how long will it hold up. It seemed to melt the cast pretty well and I didn't see any cracks afterwords. I just wanted to build up a little ledge to hold the caps in. So what do you think?

And what happens when he blows that U-joint again? The smart thing to do would involve replacing the straps (if that's all that was broken), removing the broken bolts for the straps and replacing, or replacing the whole yoke.

Now, in order to change the u-joint, you'll have to torch the old one out of the now-welded yoke and then replace the yoke AND pinion seal. Not a fun trail repair!

Hey, it was his call. I gave him all the options but he has a pair of D60s on the way anyway so this is just until he has those set up.

Re: Welding rear pinion yoke ?!?

Ive done that same repair a couple of times on a D35. They have always held untill I was able to replace them. I ran one on a Sunday up Claw Hammer, and Sledge Hammer, then replaced it on Monday and threw it into the emergency parts box.
I did not weld the caps though to the yoke. I just battery welded a ridge, and then grinded it out, like the original tab(more or less), so I was able to still remove the Joint, later.

Wow, you can get a nice tan on your arms, from welding with no shirt on.

I welded some washers(cut in half) in place of the tabs, so I could still replace the u-joint if needed. I ran mine that way for 6 months, then replaced the yoke. You should be alright. Just keep a tow bar handy, just in case.
