    I'm looking to buy a '79 Fj40 and the owner says it has a bad rear pinion. Would swapping mini axles into this be a good or bad thing? Would the knuckles still have to be rotated on a SOA?
    thanks.

    The mini axle is centered, the 40 is not.

    Like Gumby mentioned, the mini rear axle is centered, not a good optinon with the offest rcruiser t/c.

    The front axles arn't bad... but not as beefy as the Cruiser one, they do have more rotation than a stock FJ40. Why not just replace the rear 3rd with a complete used one? I sell them all the time form $50-100... easy swap, under 2 hrs...

    Kurt's got it-just buy a used 3rd member and swap. Man-a-fre has used 3rds for $50 on their website right now!

    I say it is a bad thing because your front diff will be 3.70 and the mini diff would be 4.11. Get a 3rd from an 81-84 FJ60 and it will fit the driveshaft bolt pattern, gear ratio (US), etc.

    Uh, the axles are identical, but the Cruiser diff is larger.

    Only the short side inner and both outers are the same dimensionally...

    Front end.
