I feel convicted, after years of reading & learning from Toyota & Honda forums..im finally chiming in.
So I found a use for the harbor freight 3/4" set thats been rusting away. I enjoy tool making for more than the savings but the process which hones skills. Previous owner of my 88 4wd put 2.5" lift blocks between upp control arms/ball joints. Lifting stretched out pass side cv so that inner axle always popped out of fr diff, leaking mucho fluid. After losing lift blocks, it was time to replace pass side output shaft seal ("inner diff seal"). Innermost axle bolting to middle axle via 6 - 17mm nuts/studs (Birfield, is it?) mic'd@33mm..the machined surface of innermost axle just after splines with the 6 studded flange. Ok, so I measured harb freights 3/4" drive 3" extension..twas about 37mm at shouldered drive diameter. I ground it down to 33.25mm (realize - grinding doesnt mean perfection, ie: out of round, unwanted & inconsistent tapers, etc MAY OCCUR). After grinding drive end of 3" extension so that it fit into diff carrier bearing as snug as innermost axle did...I STOPPED GRINDING. Now for the fun: I inverted 3" extension into 3/4" dr socket size: 1 7/8" - 12pt (pictured). This works nicely because when working on ground its very nice to have a pilot tool (3/4dr - 3"ext shank pilot the ID of oil seal into diff bearing. This eliminates outer "walking" of drivers such as pipes, sockets, etc. So this setup very effortlessly ('cept the 2hrs I spent grinding/trying, grinding/trying...) Anyhoo, Just like a clutch pilot tool, the 3" ext inverted into the big chrome chinese 12point socket ended up being my 1st & final attempt at getting this axle seal flush & square. **Use LOTS of diff grease on outside & inside of seal and especially grease drive end of 3" ext which is, piloting the tool with seal...into the diff. I was careful to initiate grinding of the cheap chrome paperweight...I mean 3" ext.. AT DRIVE END of the 3/4" dr tool to which grinding I relied on an intended taper to gradually (after several trips from grinding back to diff...back 'n forth) to finally fit into diff just as smooth as the axle itself did. I speak like this to those who may not be as well-versed in tool making...those lacking patience: google OTC seal installer! Thanks, it was a fun day!
