[BJ 73 TD]

hello,
longfield or newfield.... that is the question!!!!???

I want know, too, if there are differences between BJ70 inner axles/birfields FJ60 inner axles/birfields, beacause I'dd like to buy a 30-spline kit for my BJ70 (http://www.longfieldsuperaxles.com), so I try to found a corrispondece Landcruiser US model that have my same axles!

I've broken 2 Newfields, 0 Longs. Longs are a far better birf IMHO. The birf's are all the same...the long side inner on a 70 won't match a 60...the 60 is longer...so you won't be able to use a 30 spline kit.

Yap .. you can only use the birf .. from boby ..

BTW I use Newfields with my 37" with chains and no problem .. I have also the inners ..

 

[Poser]

Have someone shorten the long side.....there is enough meat on those 30 spline kits to shorten an re-spline the long side....


Not that big of a deal.


I would get the 30 spline Longs and be done with it.

If your 70 is a 1985-1989 (which your BJ70 should be), use 40 series aftermarket birfields. If yours is a 1990-1999, you can use your stock inner axles and Longfield's 27 spline or Newfield, etc. Polyperformance can make you custom length chromoly inners if you want. You just have to specify the axle shaft lengths.

My 70 is a '86... but I know that my bierfields are differents by FJ 40, but equal to BJ 42 (with ful floating axles)

I'll try to mount 30 spline kit for fj40 in my BJ70

FOR REAR AXLES:

Do you know if FJ 40 rear axles is semi floating or it's full floating?

THANKS A LOT

..only the long side inner or the short side inner too???

Take a look at your rear hubs, if they stick out beyond the wheel 5 to 10 cm then you have FF.

If you want to speak Italian email me direct at sales@Japan4X4.com My company also uses Italian. We look forward to hearing from you.

So, do you know a type of FJ 40 that has the same inner axles and birf's of BJ 70-71-73-42(they are the same)?
