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 ?
