Can you perform the One Wheel Up Test on your vcu and post the results? If you prefer you can pm me the results. Thanks.

Hi Hippo, I tested it when first installed, I jacked up the rear wheel and I could turn the wheel grabbing hold of the tyre by hand, it has a bit of resistance. You don't get any wind up when reversing on full lock just like the prop is removed. I have tried it off road, no problems yet and on grass all four wheels spin. For what I need it's better than the original.

Hippo was probably not wanting to advertise the company.
I think it's strange that they have 3 different types, I've not heard that one before.
How did you test it off road? Was it just on grass?

Hi Duncp,
No off road too nothing serious though just up some rocky slops, if you are using the Freelander for just general off roading it's good. i found that there is no wind up at all on reversing full lock, obviously the more the more the front wheels slip the stiffer the VCU gets. i tried the four wheels spinning on grass to insure all four wheels would spin.

I put that in. didn't want to advertise.
For a company to say they offer different versions of a vcu, is difficult to understand, when looking into the detail of how they work. What I think a company would be trying to say is they've set the "activation" point different to the original, which LR (GKN) produced. The "loose" version being one which passes less power to the rear wheels until it needs to, when 4x4 is needed. The "competition" version which presumably would activate sooner than the original giving the driver a more permanent 4x4 action as it "activates" sooner to reduce spin, giving 4x4 quicker and more often. The thing is vcu's "activate" in such a way that they do so to give what you need, dependent on the situation. Proportional to requirements if you like.

Sounds like a bit of a gimick to me mate. I've never had a drama with the standard one.
I would of thought a loose one would slip if to much was asked of it and a stiff one would fail a lot sooner than a standard one.

Possibly? i'm not sure how they do it, the guy i spoke to there was very helpful, i don't off road much only sometimes on my way to work if i take the scenic route so it suits me fine and less worry about putting stress on the IRD.I put that in. didn't want to advertise.

Sometimes the loose ones are too loose which is when they never have the strength to pass power to the rear wheels. Other loose ones are looser than the average original, but still work ok. A quicker reacting vcu would be worked harder so in theory would cause more stress in the transmission. Like when on road say. LR and GKN must have worked on the vcu to balance need for 4x4, reaction time and mechanical stress causing failure due to over working.

It would be good if you could one wheel up test it with a weight and bar. This tells us the effort (force) needed to turn the wheel, as gravity pulls the weight to the ground. It's possible to turn the wheel by hand but it's too difficult to compare the force needed to do this. If your not able to one wheel up test it then that's ok.

Yes, there is another company that has been mentioned in the past that sells ones that are way to loose. I think I'll stay with the standard one when I come to change it lol.
