Seen several MG's with broken axles. Seems the same problem there.
To say this....Triumphs aren't the only cars which leaving wheels on the
track lanes.
There are BMW, Porsches, VW Golf's and hundreds of other cars which can't
stand racing stress on the axles.
They replace axles after some hours of racing - that's it. I could imagine
that axles don't last forever - like spark plugs.

OK so why can't you use the MG design?
To pricey or hard to install?

"Just curious, but has anyone looked at MGB axles? What is their
history?"
The earlier MG cars, including A & early B, used a nice fully-floating
axle design. The later B uses a (very robust) semi-floating axle.

List,
I have mentioned this before but I took a TR3/4 Hub into our Axle
Engineering folks at John Deere for a thorough examination. One of the
outcomes was that "it is designed to break".....this might have been a
bit facetious, but the fact is that it works well to have the hub break
before the axle.
The stress risers are located in the hub in such a way that breaks in a
conical shape and traps the hub and wheel on the car. If you look, the
cutting tool comes to sharp corners with no attempt at a radius.
In search of the weakest link, the axle is next. My vote remains with
Southwick.
Just curious, but has anyone looked at MGB axles? What is their history?

Driving slow is not the answer either. I broke the left rear axle on
the Warwick in turn 6 at Roebling Road. I was lucky in that turn 6 is a
slow carasoul and when the axle broke the wheel exited out the
fiberglass body20quickly. The brake backing plate just bulldozed the
Georgia sand out of the way and did not dig in enough to cause it to
roll over. The Warwick uses the same TR3 hub and tapered axle even
though it is a De Dion axle. The same as the TR3 all the way to the
same key way with stake point to prevent the key from going in too far.
This is right where it broke. The same place as any TR3 & TR4 I have
seen.
A year later and the Warwick is back together but with a redisigned De
Dion axle with hubs from a 280ZX. Sorry but I am not racing with any
more TR hubs....
