    Just wanted to know how much weaker are the 80's era toyota truck axles compared to the fj40's. I know about the gear ratio difference and all that, but just wanted to know if they are bullet proof like the fj40. I have an idea brewing, or maybe I just farted!
    Let me have it...............

    I'm running minitruck axle shafts in my rear axle, and haven't broken any, nor have a few other guys who wheel pretty hard, and broke a few cruiser rear shafts.

    The 8" R&P isn't as strong, but the FJ coarse spline pinion isn't as strong as the fine-spline mini...

    i've heard that 84-85 truck birf's are stronger than the 40's.
    the truck axles are not C-clip axles also, i call that a plus.

    so it's looking like the truck axles are stronger not weaker.

    I'd say pound for pound, the mine stuff is stronger. The axles are the same size and don't have those pesky c-clips. The dropouts are incredibly strong for their size, but in my honest opinion not strong enough for the weight to torque ratio that most cruiser have. The R&P in the 80 series is a case in point. They are mini size and prone to breakage, then again they are hi pinion-reverse rotation.... Maybe that makes them weaker.
