    make little 1/8 plates a bit bigger than the hole and weld them up
    then drill and tap a hole in 1 of the plates for a grease zerk
    then put a half a tube of grease in it

    I would think it is cast steel... Cast steel you can weld easy. Cast iron.....Is something else. Can you get one to try welding on?? Warm it up, weld and cool down slowly.

    E7018 or allstate 275. Mig, Hard wire E60. I think that's the number. Or a S.S. rod or wire.

    my diff is the same as yours and yes you can weld to that housing. I think a CVboot would not keep the grease where you want it.
    centrafugal forces will throw the grease out the holes and into the boot,imo

    Good point, do you also have a Mini diff?
    What engine do you have?
    Thanks

    What amazes me is those bearings on the diff holding the pull. Do you have them bolted "flat" so that they are being pulled on sideways or are they mounted so that under load the bottom is being compressed by the pull of the engine?

    I have seen them both ways and as said above the abuse they will take amazes me.

    Neat buggy. I am going to go watch the videos now but the net here is kinda slow tonight so may be a bit....
    Now that NOBAMA has PROVEN he is the absolute WORST president in the history of history Jimmy Carter can thank him for stealing the dunce crown.

    Lets hope the next guy repeals NObama care along with the rest of the stupid crap this blight on our windshield has done.

    I am going to bolt them flat onto(on top of) the chassis, so the engine will pull on their bolts, do you think there could be problems?

    I doubt there will be issues as I said I have seen those kinda bearings take crazy abuse but myself I would want the flats of the bottoms being pulled right towards the engine just to feel better behind the wheel. I hate to build a problem into something if I can help it.

    Also I will point out if you look for the user Nikken on this site there are not many harder than him on a buggy (This guy get airplane kinda airtime) and he has a jackshaft setup with these bearings like this. BUT he does have a geardown AFTER the bearings so that does make it easier on them.
