I Have read a lot here on this site about Sheared axle studs on Landcruiser 75s rear axle, well yep i did the whole 6 on my Troopie , lucky i was in Town so just went home and fixed it , , phoned the suppliers in Brissy and they told me then that yeh people have had problems and said no solution has been heard of yet , I told well i know of one ??? , I put it all back together with a new oil seal , loctited the threads Then carefully don 3 spot welds around the edge being carefull not to apply to much heat in one spot at a time so cooled each weld with water immediately, so far no problems but do have an 800w inverter so will carry an angle grinder just in case when going bush.Any more troubles and in goes an Air locker and leave the detroit in the front as it has been ok so far.

I was always taught that cooling weld with water is a no no as it weakens the metal and they should be allowed to cool slowly.

Thanks for your reply Patrolman Pat, I'm no engineer but's only 3 little spot welds to help the 6 studs so i guess it's not real important and it seems to be holding ok . just don't know if i should trust the lockers behaviour to do the Canning,I will more than likely later replace it with an ARB air.

Hi All,
Mild steel really does'nt matter if you quench it straight after welding,but once you leave this low carbon content steel the red flag should be find out how weld,mid, high carbon content fe,alloys you should really refer to trade text..I no this sounds boring but the life you save could be your own....Hope your welds stay true.

They break the studs without any form of diff lock or lsd.

Thanks to you all for the suggestions and hints, I really don't think i've done any harm to it by welding as i only done 3 small spot welds to aid the studs,not as if i welded all the way around, was out in some very rugged country yesterday near Mt Isa and did not even get a click from it, I did have the axle out a few days before the drama's and just maybe the nuts were loose thus giving it the start it needed to sheer, It will be a few months yet before i head to the Canning so if i have any doubts i will replace with an air locker, That locker will fit older Cruisers front Diffs so i been told so i could sell it .

I second that. Watch for any leaking diff oil on your rims, and keep a torque wrench handy to check them now and then. see if you have a hub that can slot an extra 2 locating pins in there to help.
