Vehicle owner here. Upon inspecting the PTO winch and selector cable after this video. I have figured out that the selector cable was out of adjustment, causing the PTO drive shaft to not fully engage, and so the grinding noise when the winch loads up with the weight of the truck. I was able to use enough pressure from the winch, with a little drive of the wheels and unstuck my rear crossmember from the bank.
@colinduncan908 That’s very useful to know as I have an identical Perentie 6x6 to what you have and I’m actually fixing up the PTO atm. By the way can you tell me which wheels and tyres you have on it please. I’m looking at replacing the 7.50 R16’s it came with as they are over 10 years old and I don’t trust them on the highway. I’m trying to workout what are the tallest off road tyres that will fit with and without playing with the offsets. Not looking to go too wide as it’s mainly for sand driving and I know from having lived on Straddie that skinny tyres do just fine in the sand as long as you lower your tyre pressures appropriately. I would like to go to taller tyres to effectively increase overall gearing albeit slightly, gain a little extra ground clearance and increase the tyre footprint when running low pressures for sand driving.
