Re: Need Advise !
Douglas, I don't think we're ignoring your post, it's just hard for me anyway to understand. I think the ring gear support case doesn't have any holes except where the cross pins go through. I've thought about just welding up the teeth on the spider gears to where they can't roll into the axle gears but that might not be strong enough. If you open up the support case and welded the spider gears to the one axle gear that would still be in there, that would lock up the diff. You could fill the thing with alum. as long as the splines on the axle gears remained clean. Do a search on aluminum there are quite a few posts about it.
