Spin too hard and knock !


Hello, on my old (15 years) Bosch washer, the spin sometimes seems too "strong", all knocks and it finished to brake both the driving belt and the drain hose (hole in it) !
This machine was supposed to detect any "off balance" (it worked like this since now) :
-> Could it be this detection system that is out of order ?
-> Or could it be the 2 "shock absorbers" that have become loose and so to be changed ?

Thanks for a rapid answer if possible (the dirty cloth pile is growing !)
