Hi sorry can't help with the mechanic,but was just wondering where are those tracks in you profile photo?look very interesting thanks garry
The muddy rainforest one is to the east of moondarra reservoir around rintoul creek I think it's called. Just before rawson/walhalla.
I had been in 4wds plenty of times but this was the first track I ever drove in my own and my idiot mate took us down a purple dotted track (motorcycle only)
Took us 8 hours to travel 10kms and then the end of the track was impossible unless you were willing to break stuff.
We stopped at the point of the start of this video and had to turn around
