Land Rover Range Rover - 1990 vs 2004 -  

Did it work? :)

There are no lockers. We don't know if center visco has that hard setup or if it's stuck in hump. Handling seems to be fine.

@@4x4.tests.on.rollers It's true that the viscous coupling in the Range Rover Classic's transfer case isn't known for being particularly hard. It has a reputation for being a little lazy to react. Now, criticism often comes from off-roading, in the low range. If you look at how a VW T3 performs in the same situation, you can see that it might be good enough for this kind of test. Now, just the difference in the operating concept of a visco + differential VS Torsen differential goes some way to explaining the visual difference in operation. But I still ask myself the same question One thing that could have been interesting was to have one of the rare Range Classic in the higher trim levels with the V8, some models of which are equipped for the first time with the ETC system acting only on the rear wheels. It would also be interesting to compare it with the Range P38a...

@@Softroader I think ETC on rear axle came up in 1993. It would be great to test such version but there is not much of them here...

@@4x4.tests.on.rollersIn France, ETC arrived with the LSE version in 1992.

That's correct. Usually engine traction control goes off but brake traction control remains active.

There used to be side bars but we removed them, they were giving a lot of traction. It's much better to do slight corrections with steering wheel.

@@4x4.tests.on.rollers your answer inspired another suggestion: every roller is fixed to the ground by vehicle weight, what if you make the with two bases above each other, so a base is fixed to the ground by the vehicle's weight and the above base which connected to lower base by a rotating movement or a single DOF around vertical axis, and the above base must be fixed to lower base then this fixture freed after the vehicle's wheel is on the rollers!

@@LawatheMEid Unfortunately I don't understand what you mean, I don't see it. What would be the purpose?

@@4x4.tests.on.rollers to make the rollers spun with the wheel steering, in this case We simulate a horizontal two dimensional frictionless situation (wide spot of ice on the road).

@@LawatheMEid Oh I got it now. It would be complicated cause rollers would be higher. That means that all four wheels would have to be on some kind of platform in order to not exceed the suspension travel and to keep the car balanced.

Bring it 👍

Yeap, we noticed that during the test that it behaves like it was locked for good.

Couldn’t you have tried foot brake as handbrake won’t affect axles on the old Range Rover

@@dan8789 We tried in many different cars, it never worked.

@@4x4.tests.on.rollers Would be interesting in an older 4x4 like this without traction control to install valves on the brake lines so that you could control brake pressure to individual brakes and stop the unloaded ones spinning

Still waiting for it...
