I’m after a bit of advice & guidance here people - my 2017 300 ST (with 25000 miles) has started creaking from the rear suspension when driving. The strange thing is that when going over speed bumps (slowly of course ) and “general” undulations in the road the suspension is quiet, however when driving over literally a very minor bump in the road the rear suspension creaks like mad?? I can’t decide which side it is - I think it’s the passenger side but not 100% - it also doesn’t make any difference if someone is sat in the back or not Anyone else had this annoying issue - if so how did you cure it? TIA
