That is exactly my experience and while the silicon lube will help it probably won’t get rid of it. That will happen when the car gets back into its natural environment, especially in Wales, wet weather.

i know I’m Welsh!

Mine had this last year. The bushes had just been replaced within the previous 6 months. Sadly they were cheap Chinese So I paid for genuine parts from an Indie. Noise gone.

People used to turn and watch me it was so noisy. Previously owned 1999 Disco 2 TD5
Disco 3 HSE TDV6 2007
Gone 2007 TDV8 RRS1 in Buckingham Blue.

How do know if the knocking at the front has been sorted?

You can hear the knocking at the rear better

Mine is that noisy  Steve.

Do not use any oil based product (WD40 etc) or soap.

Use a silicon spray or get some silicon grease from a cycle shop and get it in the bushes. Silicon will not affect the bush material.

I ummmmm, found some silicone spray in work 😁 Steve.

I’m always “finding” things at work

I`m gonna sound like a right melt now....I`ve just had a look underneath, armed with my trusty silicone spray and I can`t really make out or see where the ARB bushes are  Steve.

Just behind your front brake caliper , and above the control arm , you will see the ARB
Follow it under the chassis and you will see the bush

I think the rears are level with the front of the rear wheel (if that makes sense)
Better of in off road height to see

Ah right, cheers matey I didn`t put it in off road mode...d`oh..would make it easier  Steve.

No problem Steve
I’ve just tested my theory and I can see them

 Steve.
