Pinion chips, how to fix it?

FWIW I daily Drove my truck for over 3 months with a pinion that had two chipped teeth and one completely missing, and that was back when i had a 10 bolt still, driving back and forth from Raleigh multiple times, towing the trailer with random vehicles on it, plus just general daily driving. And the whole time the pieces of teeth had been floating around in the gears. All it ever did was make noise when i let off the gas at highway speeds, and one day I was like hey I should take a look just to make sure that noise isn't a bad thing . . . :lol:


From what I've seen those unimogs portals are the weak point anyway, I'd be more worried bout them. Maybe run the chipped pinion in the front axle, so then at least you can drive around in 2wd on the road and not have stress on it it till in 4wd - if your still trying to be able to street her.

The portal boxes are the weak points on the 404s. These are much stronger than the boxes on the 404s, the gears in the boxes are also straight cut vs. helical cut in the 404s. I'd be willing to bet the diff gears would be destroyed before the portal boxes on these axles. I am going to drive this on the street a bit but a little noise doesn't bother me.
 
thats is a clamshell design the shims for the carrier could be under the races or possibly between the axle tubes where it meets the hogs head. there would have to be a way to adjust back lash or they would definetly self destruct in short order.

Right, that's my thinking as well but looking in from the pinion hole there are no shims on the side of the carrier that I see. Maybe they are just on the other side in this particular r&p.
 
Not the comparring picture your original shots, third one down. It looked a little blue on my end. I was just a thought. I agree with the above assumption that the side to side adjustment would be on how its bolted to the tubes.
