The Spit?GT-6 rears are pretty strong, except for the early ones. I've seen stub axle & pinion gear shaft breakage on them.
They are all prone to bashing in the side & spyder gear thrusts, resulting in a mysterious clunk.
Rear gears in general are pretty rugged and maintenance free, except for oil changes. This is one of the biggest problems with TR rears, no oil drain plug on most TRs. Also running low on oil cooks a lot of them.
In this case, like I said, I wouldn't even speculate, it's a disaster!!!!

: I considered it but can't convince

: I've held off speculating on the cause
: of
: failure... because I really can't come
: up with anything, based on what I see
: in the (good) pictures. Obviously the
: carrier pretty much disintegrated. The
: spyder gear shaft looks like it was in
: place, and there doesn't appear to be
: major gear damage, suggesting that this
: was immediate catastrophic failure.
: What is also unusual is a failure like
: this, with an open differential. Over
: the years I have seen a few failures
: similar, on race cars with sticky tires
: and locked rears, where there isn't
: enough left to make a determination of
: what the cause was...

: Hi.
: It's somewhat modified but I barely

: only 4000 RPMs
