Thanks fellas
Just been to cape York, while checking my tyres noticed a 30mm crack in d/s UCA so i rang nissan as its only 8 months old but they told me that most likely it wont be covered due to the roads that im driving on, they offered to tilt tray it from Bamaga to Cairns but said i would have to pay for it if this was the case (bad roads ) so options were to drive with torn UCA , weld UCA and void warranty and maybe weaken it or tilt tray and possibly pay large cost if rejected by nissan,
so after many calls and running around l ended up welding it and continued my trip but taking it a fair bit slower I've made it to cook town so I might hang around till I can replace it
So thanks again
Cheers
