    Would someone be able to verify that this is a inner axle seal that has given out?!

    My driverside birfield seems to be leaking a mix of grease and diff oil. It would be awesome if someone could verify my theory? What is the best rebuild kit to buy?

    Spacers for body of Aisin part-time hub when using later (longer) CV's aka Birfields

    Dunno if anyone's done this, but when you fit later CV's (the longer ones) [what you guys call 'Birfields'] on a part-time 4wd 80 with Aisin hubs the shafts of the CV's take up all the space inside the back of the hub (once new snap-ring grooves have been cut to correct the CV position) and I've...

    1992 FJ80 Birfield and Axle Questions

    Hi guys, long story short, I had a major failure of my brake hardlines this past weekend driving to a camping trip. Lots of smoke from the caliper area. After we towed the truck home we started tearing apart the knuckles to change the seals and overhaul everything, (I had noticed my seals were...

    Longfield front axle shaft / birfield won't come out

    I have the driver front on a '78 FJ40 front axle tore down to the inner knuckle. I am unable to get the Longfield axle out. I've lined up the flat spots and everything but the trunion races have been removed, but it won't come out. It looks and feels as it's getting stuck in the inner knuckle...

    Knuckle rebuild + upgrade questions

    Planning a knuckle rebuild on my 60 and am considering upgrading the birfield joints and possibly axles during the rebuild since I’ll already be in there. Unfortunately I’ll have to make this decision in advance as I’ll have to complete the rebuild in a maximum of four days. I’ve been toying...

    Drive an FJ60 without front axle?

    Hey all, I'm in the process of rebuilding the knuckles on my '85 FJ60. I've got everything apart right now, but while separating the birfield joint from the axle, the snap ring that keeps them together, well...snapped. I apparently didn't do enough research to know this was common so I...

    91 FJ-80 Birf wear - how much is too much?

    Front Axle Rebuild

    Noticed some sludge coming from the wheel nuts a few days ago. Thinking I have a bad inner axle seal. Here's the writeup from a local shop: "Your front diff fluid is contaminated with knuckle grease due to the bad inner axle seals and has turned into a nasty mud. It is going to require...

    Birfield Rebuild?

    I'm going to be starting my axle rebuild tonight and ran into another FJ80 owner who said something about rebuilding the actual birf's. I'm planning on removing the axle from the birf and cleaning the old grease out (haven't determined if I'll need to tear apart the birf for cleaning). The...

    Aftermarket Birfield Joint

    Has anyone used and have a good review of any aftermarket Birfields for 80 series cruisers? I have a 94 cruiser and I have had both birfields rebuilt.

    Nitro Birfield Assembly

    I bought a pair of non-chromoly Nitro birfields, and the cage/star aren't the same as stock. I took them apart to grease them up, but now I can't figure out which part of the star and which part of the cage face out. The FSM doesn't help here since there's no "flat" or "protruding" side on the...
