<BR>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.
<BR>
<BR>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.
<BR>
<BR>In search of the weakest link, the axle is next. My vote remains with Southwick.
<BR>
<BR>Just curious, but has anyone looked at MGB axles? What is their history?

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 body quickly. 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.
<BR>
<BR>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....
