Alloffroad #137 - 4x4 Victorian High Country Discovery 4 Rollover

I don’t fully understand how the engine would stall with an auto box and torque converter.

I don’t fully understand how the engine would stall with an auto box and torque converter.

They do stall quite easily - especially on steep, long sand dunes and hills. Typically when the right boot was not used enough.

BTW, Mark (owner of D4 in roll-over) is on here - SimmAus. I have been on quite a few trips with him including VHC, Firetruck Hill at Lidsdale SF, etc. He is a really nice guy and such a shame it happened to him.

Cheers,
Rob

It is a hard lesson in how easily things can go wrong and being aware of the potential to stall in extreme situations is important.

Poor, poor bastard. That's God awful. My 'new to me' D3 stalls on the odd occasion (only when slowing down with my foot off the accelerator), but that is due to the low pressure fuel pump being on the way out. Would hate that to happen to me on a steep slope.

Good tip about engaging Hill Descent Control (HDC) on difficult terrain for both climbing and descending.
They stated that HDC works even if the engine has stalled, and suggested that if it had been engaged during the climb the situation that led to the rollover may have been avoided.
Do any experts here have any further HDC advice or caveats to add please?

Could he have jumped on the brake pedal.....??

How hard is it to brake a D4 without engine running??

I watched that vid the other day, and I'm surprised that the swearing was only mild. It was a very nasty roll, and I'm glad Mark is ok.

Looks to me that the suspension was set at max max height. I wonder if he had LLAMS or rods plus LR off road height set. This would have reduced the droop to almost nothing. Surely that could contribute to a higher centre of gravity and also not all 4 wheels in contact with the ground. That combine with dropping in the hole would have been his undoing. Good to see that the driver is OK.
I know that when I have had that setting the car has very little grip and is only really usefull used sparingly. Good for getting out of deep ruts. I am not sure that HDC would work if the ignition or engine was turned off if indeed it was.
A friend of mine in her auto 80 series had a very similar rollover. Car was written off.

The D4 looked to be loaded up to the hilt which would have been a contributing factor in this roll over one would think.

Do we think it’s time this forum grew up a little on the extreme enforcement of mild swearing rules? As far as I am aware most if not all of us are adults here and even my kids have been exposed to mild swearing out ther in the real world since they went to school.

not having a go at you personally LRD414, but really?
