Viscous Coupling

[BO00YA]

Hey guys,

I am pretty new to the forum. I have a 2000 XEDi Freelander and i am suspicious of my Freelander Viscous Coupling. I have done the one wheel jacked up method and unfortunately it doesn't turn. So i suspect it is seized.

With some research i have found that they have brought out a revised VCU which came out in the later models.

Mine looks like this


Is this the from the later models?


I've been told by a Land Rover garage that the single cylinder VCU (Second picture) is from a V6 and might not fit my 1.8L.

So i don't know if it is the revised VCU or just from a V6.

Any information would be greatly appreciated.

Thanks in advance.

Ok. Not convinced with my first test. I did the dot method. I went around the block and once i got home i checked the aligned dots on the shafts and they are no longer aligned which would indicate the VCU is not seized?...Now i am confused...

Jack up 1 REAR wheel .... Put a wheel brace on a wheel nut and then stand on it ...should turn the wheel if not seized
... (It will be hard to turn the wheel)

Hey Mike,

Yeh handbrake off and in first gear. I went off Garrycol's thread.

Fair enough .....

Another way to do it ....
Tailshaft in the left hand side of the photo ... You can see a space at the "uni joint" that you can slide a bar through ....


1: To turn the Tailshaft between the rear diff & VCU
Both rear wheels off ground / 1st gear / give it a 2 arm + leg pull on the bar //// CHOCK THE FRONT WHEELS /// USE AXLE STANDS

2: To turn the Tailshaft between the engine & VCU
Put the rear wheels on the ground .... hand brake on ... gearbox in neutral (not in park or in gear) give it a 2 arm + leg pull on the bar

I went off Garrycol's thread.

Send him a PM

Hey Mike,

Thanks, I'll give it a go. I need to invest in some stands first.

Thanks heaps for your help mate.

The correct VCU is the first pic - I have no idea what the second pic is of. As I PMd - the VCU comprises the VCU and a large vibration damper.

Oh - if the wheel did not move with the test but the dots have moved - then one of the tests was not done correctly.

In the test where the wheel is lifted off the ground - the wheel will be difficult to turn but if the VCU is OK it will turn with steady pressure - pushing at it in an ad hoc manner will do nothing - steady pressure is required.
