shearing landcruiser axle pins... help

[chevJ40]

gday guys driving a fj40 with full floating rear end and with a v8 in front i am constantly shearing axle studs and drive pins what are the alternative keeping in mind i have to keep the colletts that locate the axle to the housing i heard 60 series or 80 series 1 of the 2 have bigger pins is this true? and are they the same locating system i.e collets(cone washers)
cheers

I think youll fine 100 series is bigger once again, with 10mm studs, c/w with 8mm 80 series studs. Have a look in the bible at the top of the page, there is in article in there on how to replace.

I've heard of some guys replacing the 7mm studs & nuts with Unbreako bolts or doing the 10mm stud conversion.
Have a look in the Bible area there is a how to section to fix this problem.
I'm about to have Cheezy fit a 75 diff under mine and I've been sussing this out too.

There is normaly a reason for these braking

Check the housing is not bent

the 100series has 10mm studs which are what the guys with v8's have been putting in

however, as STIKA said, power is not the only reason these shear, a bent housing can cause them to shear. You should get your housing checked before you do anything.

probably more expensive than fitting 10mm studs.

Studs are about $2ea from toyota, then you need someone to drill your axle flange, or do it yourself if you have the ability to grind a drill to the correct taper.

You need the collets to go with them as well that what expensive from toyota. I made a cutter up from a drill and it dont work too well . Very steep taper, with only 2 flutes on the drill it moves around/chatters and the holes arnt round and the axle is tough material aswell. I had a 4 flute cutter specialy made for this task and get purfectly matched holes to the collets for a strong connection. The cutter cost me lots of $$$$$$ so i dont lend it out as it could be easyly damaged in a tough axle if the speed and cutting lube arnt right.
