Herman, do you have to sent the broken bar back to JS, so they can figure out what happend?

I personally think that when milling the hex on the bar a miniscule fracture developed.



I would think the supplier/manufacturer would out of general professionalism would want to study the broken bar, unless this is a common failure for their product, unbeknownst to us, or they don't care. I am sure the op would be willing to cut off the end say up to 8" and return ship at their cost. I don't see how any hammering without very visible abuse could cause this issue in the first place, maybe only aggravate a hidden defect. I would at this point in the discussion insist on replacing both bars if my car.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
