Hi, I have a major issue with the suspension on my 2012 E Class E220, hoping there’s some help on here as 3 garages have failed to find anything wrong with my vehicle. Here are the symptoms I am experiencing.

Worn inner shoulders on tyres
Creaking on rear passenger side
Banging on front and rear of vehicle
Juddering when cornering at passenger rear
Road holding is terrible

The wheel alignment has been checked and is spot on. All suspension bushes checked and ok. Anti roll bars checked and ok. Shocks checked and ok.

Theirs something clearly wrong with the handling of this car it’s driving me mad, any advice would be appreciated
