Sounds like the general opinion is applying the grease will do the trick but last year, I had what I considered as 'clunking' when braking especially when turning the wheel at slow speeds and coming to a halt. Dealer spent 6 months trying to fix.
After replacing steering rack, brakes (whole assembly), bushes, suspension etc etc, it eventually turned out to be the engine mounting brackets. Fortunately, all the work was done under warranty.
