Folks, I have written a kind of trip report here:
http://www.ausjeepoffroad.com/forum/...24#post1652224
Overall, I am gobsmacked my 24 yo car managed to do this trip without incident given the treacherous trail conditions north of William Creek. It performed flawlessly, and although the tyres were New, I had to baby them to avoid any early tyre failures or even suspension damage.
My drum brakes had some dust in them when I eventually returned to the blacktop. It felt like I was driving with my handbrake up, and made occasional UFO sounds.
As I mentioned in the piece, I would have expected few things would force me into 4LO, but the Oodnadatta Track southbound at Mount Dutton was it. Rocky and heavily corrugated, even though the surrounding landscape was breathtakingly beautiful.
At Halligan Bay, there were plenty of cowboys travelling the track at dangerously high speeds and doing reckless overtaking with bulldust everywhere. One of them arrived at the campsite and got stuck in the sand after revving his engine to show off (Ford Ranger). Embarrassing. Had to be pulled out. Must have been running tyre pressures at 50psi.
I am back in semi civilisation, had all the fluids drained and a major service, including tyre inspection, rotation and alignment. Car drives like it just rolled off the dealership. Back to shopping and family duties without repair or modification. Same tyres....
