I have had the same thing... It turned out that after I had replaced the lower control arms, I had not fully tightened up the bolt that goes through the large rubber bush. It was allowing the slightest of movement that transformed into a loud crack when it moved. Only happened in carparks and pulling out of drives etc, all low speed.

Re your comments on the ARB links, I noticed this too when removing/replacing them. One side (can't remember which now, I think RHS) required significant effort on the ARB to remove/fit the droplink, whilst the other side was easy peasy. .

Thanks. I'll take a look once I'm back from Poland.

Tuono man for sure. I had an RSV Factory before but found it too hard on my wrists. The Tuono Factory has all the good bits of the RSV without any of the drawbacks. 2006 FFRR 4.2 Supercharged Vogue SE

yes suncream. Was more when taking foot off of the brake and pulling off though. I have a similar issue to the op though and am ignoring it as it only happens at the extremes of lock. Personally i think it is the ns bottom ball joint with a little wear in it. Will get them to have a look as its due for a service soon. There is nothing that can't be fixed with a hammer😜😜

Disconnect the steering rack track rod ends from the hub but leave them on the rack grab hold of the bit behind track rid end and push / pull if the steering joint moves in / out its the inner track rod ends that are bolted to the rack under the big boot that are shot i had to replace both mine

Just to confirm i am not on about the ones that bolt to the hub its the ones that bolt to the end of the rack under the black boot  onto no6 Range Rover

Well, I just got back from the specialist and it needs a new steering rack. Great. £2.5k that's going to be.
Oh well, welcome to FFRR ownership I guess. 2006 FFRR 4.2 Supercharged Vogue SE

i'd be tempted to get a second opinion , just in case its not the rack.. ... - .- -.

If you do need a new steering rack then there are a few second hand on Ebay starting at £250.
They are all P/N QEB000083 which I think will fit the SC but I've not been able to confirm.  

Are all the racks on the FFRR the same regardless of model year? I thought some had variable ratio steering and some didn't.
I'm going to try and source a used or re-manufactured rack. £1700+vat is just bonkers for a new one. 2006 FFRR 4.2 Supercharged Vogue SE

I did. They didn't budge.
I might get a second opinion as others have suggested. Any recommendations for a place in the Berkshire sort of area? Rovertune are the guys who have diagnosed the rack by the way. I don't have any real reason to question their diagnosis but it's a shed load of cash. 2006 FFRR 4.2 Supercharged Vogue SE

But is that the same rack as on a 2006 SC? I can't seem to find anything definitive. 2006 FFRR 4.2 Supercharged Vogue SE
