Please help loud knocking noise coming from under my Range Rover
 

Sounds like a loud knock under the car as I’m driving the noise stays knocking as as long as the wheels are moving it’s a 06 Range Rover hse

Hi. Other then on a perfectly smooth road surface I had constant knocks and rattles from the front and rear of my 08 TDV8 Vogue - particularly when turning, especially going left. The problem was worn bushes on the front anti-roll bar. replacing these and drop arm suspension bushes front and rear solved the problem completely. The front anti-roll bar bushes are very awkward to fit.
