Hi guys, I have just bought a 2008 fpv territory.. I have a vey bad vibration between 70/80 kph. I have replaced the engine mounts (non genuine) transmission mount (genuine ford) rear diff bushes, front and rear CV shafts, replaced center bearing and had the front and rear tailshafts balanced.. I have replaced all the tyres. The vibration seems worse under load? Can anybody help me with this problem.
