    I did a search, including:
    https://forum.ih8mud.com/showthread.php?t=59403&page=2&highlight=aisin (where I think my question was already answered) and https://forum.ih8mud.com/showthread.php?t=63304&highlight=aisin . These two seemed helpful, but I want to make absolutely sure this will work:

    I have a '78 (June 1978) front axle that I put Longfield's in. If I order an "OEM Hub Assembly 1/79-1/90 (http://www.sor.com/clubsor/products2.tam?xax=13150&category.ctx=080-86&page#.ctx=080 part 080-86B) can I bolt this right on to my rig? I want to get brand new units, even if it means the bunches of $$ :eek: (or I may ge the Marlin Crawler rebuilt units)

    One of the posts mentioned grinding things, is there something I would have to grind, or do the Longfileds make the birf the correct length for a bolt-on Aisin???

    Thanks.

    The only thing you have to grind is the knuckle housing to fit the larger birfield in. The birfields are based off of the bigger mini truck size. Otherwise the aisins are a straight bolt on.

    I would be careful of that date from SOR... mini truck solid axles were available from 79 - 85, the splines on the hubs should count to 30, the IFS ones are 27 spline.

    Thanks for the reply. My Logfields are already in, so I'm assuming the mechanic that I had build the knuckles did whatever grinding was needed, if any... (using Longfield 27 spline birfs).

    Thanks, I'll order the Aisins :-o

    Offroad.com has a pretty good article on Aisin hubs for those who haven't seen it: http://www.off-road.com/toyota/tech/aisin/ Although it is primarily intended for identification and rebuilding purposes; there is some great tech info in there as well.

    My apologies if this article is of common knowledge... :doh:
