Went and did some digging back in the forum, seems that this has been one of those recurring topics over time, many people have entered the debate with ideas and opinions and experiences..saw some photos too. It seems the concensus of all that is:
Poor design (but it has lasted 20+ yrs), frame material too soft, bonding getting old and cracking due to UV, heat, vibration, etc. as well as strut pressure.
I think I will bow out of this one until it happens to me...but I sure hope it doesnt!
