Guys, please read this and take it on board. today i had a very lucky escape to what could have been a very hard hit, while going through Hawthorn bend on the Brands GP circuit i had a rear upright failure, the mid corner speed is well over 1oo MPH and i nearly lost the out side rear wheel!. Lesson please take a look at the age of your upright, this could have been a hell of a lot worse.

At first glance of the rather fuzzy picture it looks like it was the Hub that failed??
The Upright looks to be fine.
How many hours were on that Upright/Hub???

you cant just life them in hours a bumpy circuit like croft or coombe will fatigue them quiker than a smooth one like silverstone + kerbs contact with other cars etc

You are correct it was the hub that fail, by upright I was referring to the up right assembly, you can see its sheared off. As for hours of use very hard for me to say as I did not purchase the car from new, apologies for the poor picture adrenalin rush when changing in out, wanted to get back out.

The odd thing is how you managed to break it when you were driving so slowly.
I don't understand.

That's because your not allowed to overtake on bends and you were in front of me!

So did the stub axle part of the outer CV also shear off?
If it didn't then surely the remains of the hub would have been held by the stub axle and hub nut?

the stub axle was in one piece as the drive shafts on the SR 3 are floating, the hub snapped just at the end of the shaft! Thus detaching from the upright, I then of course lost drive as there was nothing for the drive shaft to turn

Hi Arnold,
How do you tie your car down to your trailer?
Thanks,
Ron

Ron I do use the radical centre tie downs, the are however fully inserted with locating bolts. The up right that broke on me was the rear left and it was six years old, so in my view the two real factors there are load and age., and now they are all new!

Thanks Arnold. I am sure age was mostly to blame too.
Did you replace the entire upright or just the Hub?
