H&R Spacer... Lip shaved/broke off?!

Yah, I agree again that the manufacture needs to analyse this and find root cause. The lip should not break off. Completely defeats the purpose and a false sense of security. If this was a bad lot they need to recall and purge their stock, but atleast then they will gain user confidence.

phunk

analysis: broken

what do you think they are going to hire a forensics team to look at it and say what the entire world already knows; it couldnt handle the lateral load and it broke. LOL, thats all there is to it.

hey smartarse, since im a nice guy i will coach you how things are done in the manufacturing world.

if this was a non-injury or non-life threatening piece of a car like say an emblem, i wouldn't mind as much, but a spacer/stud failure can cause serious accidents especially if one is getting false sense of security while driving.

since you don't have basic knowledge of what real manufacturers go through, any top tier manufacturer will have lab equipment in-house to do this analysis... nowhere near involved as what a forensics scientist would go through. LOL

they will first look at the angles of the break under a microscope to determine if it was a stress fracture or material fatigue or material contamination. they can also find where the load was on the lip which caused the failure to see if within design. if the material appears pure, they will run spectro-analysis to check the material alloy itself, and determine root cause.

there's basically 3 suspects. design, material contamination, wrong material combination used.

fix the problem, prevent it from reoccurring, done. if our wheel design is outside the design tolerance due to material, then that needs to be highlighted on the box/instruction manual.

the end. hope you enjoyed basic QC 8D Reporting 101.
