Roomster creaks

Just to add further investigation to skoda roomster rear  axle assembly cures?  i totally. replaced all lower suspension components (car itself body and interior like new). after 2 weeks the infamous creaking when rocking!! 😒 Just repeated the original method of tightening, the cross bolts through rubber bushes, with baggage in boot,

This time using an air gun socket used on wheel bolts. 120 nm. no noises. when rocked side to side, because the centre of bush (metal to metal)  is torqued against the retaining  bracket.... phew
