Did a bit of spannering...
Changed the track end rods, lower ball-joints, stabiliser rods, changed oil, oil filter and fitted a new steering gaiter. Stabiliser rods lasted 6 months and started rattling. I don't remember which brand I used but now I have TRW and hope they will last longer... Well its no surprise they didn't last long considering sh**** roads we have
Then went to a garage to adjust the track rods. The car feels much sharper on curves and there is no more rattling from the suspension

And ride quality has improved also
