Hi, new to this forum. Looking for any thoughts on what can been up with my disco. At speeds around 55-70mph (after 70 no rumble) I am getting a rumble/slight vibration. Still there if I put my foot on the clutch and disengage gearbox. Replaced front uj's and centre bearing on prop shaft and has a new rear shaft. I also get slight vibration when breaking into a corner could bushes, ball joints, hubs etc be the problem?
