Have you checked all control arm bushings (front and rear). 2011 RRS HSE Luxury 3.0 TDV6 Fuji White on Ebony/Ivory

I had the same issue, I went trough discs, track rod ends and the problem was still there. Turned out to be bottom arm bushings, the hydro bush had split and emptied so I replaced with solid bushing and the problem has gone, I did fit new OE bottom ball joints too but the old ones seemed fine, so I would say it was 100% the rear hydro bushes that were causing the wobble when braking.

Front lower arms news,
i have to check the others, but could it also depend on the rear ones.....?
thank you
