result of second test,new shocks fitted,hope this helps
..there thanks reply..
Ok givin i asume this isnt actually the brake inbalance across the axle and no work has been done on the axle in regards ***** ***** trailing arm bearings in which requires removal of the trailing arm which in turn if not previously marked or lined up when refitting can off set the height or imbalance so to speak..have they actually inspected arm bearing ..Its extremely common fault on all 206's inc the 206sw estate to fail MOT/test on them..so if they havent properly inspected those id say that would be something to consider getting rechecked..those 206sw have sway bars have those been checked .what about the axle frame bushings to body have those been checked..apart from that i doubt shocks would of caused this to be honest unless one was leaking..the fact that your garage have said a new axle maybe required ..in all honesty and through lots experiance with these cars replacing those axles/bearings even..replacement would likely be your best option..there are lots reconditioned units out there online etc..but rememeber the axle on the sw,estate is differant to those on the normal run of 206's...I do hope this helps
