    Default BJ40 re-gearing / knuckle and front axles



    I finally started my needed project of re-gearing the beast, I had the factory 4.11 and when I installed the 35Ē tires I could tell it just doesnít have the necessary power so I got a 5.29 Nitro ring and pinion set. Iím also changing the steering knuckle to the six shooter also the front axles. I have the ring installed on the locker already but I ran into a problem, the old pinion has 10 splines and the new Nitro has 27 splines I guess I have to order a new flange. So this is how far I got this morning. Progress will be posted.

    Yay! Toyota build porn!

    Sucks about the spline count. I see you are in Monument, but I think I have a couple 27 spline flanges laying around. I can check and measure the bolt patterns if you are interested.

    It would be great if they are the right bolt pattern, 60◊68.5

    Since it sounds like you have to replace the flange, so if you go new, consider one with multiple patterns drilled. You may be very thankful later that you did. This would be the time to do it!

    Thanks Jim
    I'm fortunate enough to have the shop, it make things much easier, back in the days I built a chopper out of my old garage and I tell you, it was a pain not having the space and the equipment

    That is the only one I can because of the weird bolt pattern, 60◊68.5 and 11mm bolt holes

    This place has plenty of different 27 spline options, even ones that have no holes drilled so you can make your own patterns!

    Curt has a great business that I always buy from which goes back to my Land Cruiser. He'll talk to you and walk you through stuff when needed. He even offered to drive to me and lend a hand when I had trouble with fuel starvation when I was stuck in the Henry Mts - that's a pretty good drive from his shop. He knows his Yotas!

    The only negative is sometimes he's on an expediation in South America (the b*stard!) but dealing with his staff is fine too.

    Well, no luck. Looks like everything I have is for the mini trucks. Found one that is close to 60x68.5 but it is for 10mm bolts, not the 11mm.

    Drill it!
    10mm to 11mm will be easy and not so much as to make it fail.

    I have to double check the lip od on the 10mm screw flange, it might be different size, we will make it work somehow
