​I have a 2011, TDV8, my rear passenger side suspension is creaking like a 1980s mattress, you can hear me coming about 400meters before i arrive,

i have replaced some of the usual suspects as part of routine maintenance, but i was under it yesterday while having 4 wheel alignment and it seems to be coming from the air bag/ strut, the strut was replaced last October. also the ride is a little hard at the rear (starting to get a squeak on the diver side rear) but not all the time. the rear airbags haven't been replaced in the 6 years I've owned her.

i am after some help on what it could be, its showing no codes, it goes up and down no problems, it creaks on the way down but not up. I have tried silicone spray on individual bushes to eliminate them without success.

any help would be appreciated. i am pulling out my hair 2011 TDV8 | overfinch genuine build | mapped

Mine did this and it turned out to be the upper outer suspension bushes. Got particularly bad in hot weather and so loud people would turn round and look..... 2012 TDV8 Vogue (L322)

I have just replaced both upper arms and bushes. 2011 TDV8 | overfinch genuine build | mapped
