This is a quick mock-up with central and rear locking diffs, high-low gearbox and live axles (notice the front diff mounted the wrong way - I've had those axles around for a while and couldn't be arsed to turn the diff around just for a mock-up). The trackwidth is narrower than 42070, whereas the wheelbase should be pretty close. (Edit: the wheels are all mounted the wrong way around, too ) Edited July 18, 2017 by suffocation Quote
schraubedrin Posted July 18, 2017 Posted July 18, 2017 Question: Wouldn't it be enough to lock the front differential to get quite a lot more truck trial capability? Quote

Expand The priority for locking would be 1) centre 2) rear 3) front Locking only the front would make it a 2wd with no steering capabilty. Locking the centre would give you min 3wd - one wheel on each axle. Quote

But isn't it far more probable that one wheel on one axle looses contact than one whole axle loosing contact? On 7/18/2017 at 7:25 PM, valenciaeric said: no steering capabilty Expand I've got to admit, i completely forgot about steering Quote
valenciaeric Posted July 18, 2017 Posted July 18, 2017 If one front wheel loses traction then all torque will go to that wheel with an open centre diff. If you lock the front diff then you will have less efficient steering and any slip from the rear wheels will transfer torque to them. Ideally, it is best just to eliminate the centre diff as the turning circle is so wide anyway and there are no drive shafts to break, just uni joints on the front. Quote

I thought that it might be improbable that both rear axles will lose grip. Anyway, thanks for this short lecture on diff locking, i quite enjoyed it Quote

MattL600 Posted July 20, 2017 Posted July 20, 2017 Lower the whole thing, remove the outriggers, use independent suspension on all wheels and swap out the bed for 4 XL motors and a W16 engine. Maybe, we can call it a dakar truck or something. (basically a fast version without all the tow truck functions :3) Quote

nick97 Posted July 29, 2017 Posted July 29, 2017 Hi all, As this is a mod topic, I have one for you. I the pictures you can see the HOG I've made using the second gear on the gearrack. Replacing the batteries is still possible, you only need to remove the gear. It took me about 30 minutes to build. The hardest part was removing the 3L axle with stop and placing a 4L with stop. And I had the tan gear on the wrong side, so it turns the wrong way. You are free to use it and/or improve it. Quote
Aventador2004 Posted July 29, 2017 Posted July 29, 2017 Nice! I don't think I will get this, so I can only look. Good mod. Quote
