doug,
have you used lockright before?
I had my first close up experience of diff locks in action last weekend at that 4x4 course I did.
There was this big rutted hill (alternately rutted so it was intentionally difficult for anybody to get close to getting up).
My truck barely got half way before she was spinning alternate wheels and I had to back back down.
There was the bosses sun who was in a 79 series cab chassis diesel ute, with front and rear lockers and absolutely unroadworthy stock tyres.
The terrain was loose soil with some rock by the way.
He cruised up that rutted hill like nothing, I could not beleive it. :eek:
The cruiser wasnt even struggling. As one front wheel would slightly begin to spin, the other would continue to drag it up.
And the cruiser has a pretty stiff suspension setup....made me think, if my hilux with the soft suspension and good tyres had lockers, imagine would I could get up more easier?
The only other vehicle to make it to the top was a GXV V8 landcruiser with traction control.
It spun wheels alot more but the ABS system enable traction to the wheels that needed it at each situation and it crawled its way up with street tyres.
Crazy what technology can do. We think our rigs are pretty tuff till something like those two cruise uphill like having a shit.
Which is why I need difflocks.......one day!
