Thread: broken straight axel

Tweet

there were clues leading to this failure that went uncorrected---the ill handleing, the toe in issues,---they should of raised an eye brow to something beyond a different toe setting--

the king pin area likely failed because of the method and quantity of material removed to get the chrome out of the king pin boss, the tapered bolt for securing the kingpin was over tightened causing the fracture--when the king pin boss failed the car was out of control--this led to further damage breaking the axle at the perch area---
Axles mounted like that with split wishbones need some rubber ends on the links to allow for a little flex/bind issues--the use of hard ends/heims will put the axle in a very high stress every time it moves in any direction

Agreed, the only axles i've ever seen break was because of an accident or been badly fitted.

I am running split whishbones and tie rod ends for the end on the wishbones, it that hight stress, and the weight of a blown bbc?

Check to see what revision axel you have (I am sure there are noticeable changes) and wether the changes to make it stronger give you a better feeling for safety. The chrome embrittlement issue? Depends on the design of the axel and what design rules were used for over kill if any. Heck don't use it too scarry!!
