Depends which model LC100 you ae talking about - but maybe it being weak was an urban myth anyway - I would be interested to hear FIRST hand experience of weak front diff - I do recall someone said the LC100 - IFS - was same as HiLux diff

There are many examples of such diff breakages . A friend of mine who runs 4wd tag a longs in NZ had a cutomer break one on a patch of ground that other vehicles had no worries with.
He was suitably horrified and his personal tour vehicle is now a Nissan.

There was an article in an older issue of 4x4 Monthly which showed that hilux and 100 ser diffs were NOT the same.

It seems you only broke them if backing uphill in reverse or snatching in the same situation.
Would possibly not be covered by warranty and classed as abnormal use.
Has anyone tried a warranty claim in this situation

"you only broke them if backing uphill in reverse or snatching".
How this rumour got going I have no idea as both 100 & 105 series Cruisers blow up diffs in any direction. Doesn't matter if they are V8 petrols, diesels, manuals or autos they all suffer the same fate. Greatest single cause of breakage is in 1st gear going forwards, lifting a wheel (which starts spinning) then regaining traction. BANG. It's alarmingly easy to do!
Unfortunately those that blow one often do a 2nd or 3rd shortly after as it seems many dealers don't know how to set a diff up correctly. But............all is not lost, & we shouldn't all rush out & buy a Nissan as although the diff is physically undersized for the weight of the car it can be rebuilt to take regular offroad use.
Autocraft in Geelong (amoung others) have developed a fix which in part involves fitting an ARB locker with other adjustments & despite repairing well over 60 diffs has only had one back. (Comp truck) Many serious about their offroading have the upgrade done beforehand.
The other confusion being these diffs are the same as in the Hilux is also incorrect. They are very similar in size but not the same despite sharing the same ARB part number for the locker.
Cheers Craig..............
HZJ105 with 4 blown diffs in 40K but no problems since upgrade.
Toyota Australia barely question a diff breakage fixing imediately under warrenty & perhaps why there is very little backlash :-))

Hi SJP,

While the 100 series front diff was a known weak spot, the 200 has the Tundra diff (USA Toyota equivalent of F250). It is much stronger and needs to be, the old reverse cut diff had issues with 272Nm of 1HZ power, unlikely to hold up to 650Nm of V8 diesel torque.

Cheers

Won't fit, it is larger and completely different. ARB locker for the 200 is not the same part number as a 100. Rear 200 is same as a 100 though, and front in the 200 is the same part number as Tundra as Captain indicated.
