So where did you find your statistics to plot the graph and what size of a population did you do it over, given that that would alter the standard deviation?

You can tell from the way the ****in things drive! I don't follow the mysticism of diagnosing them!

I havent, but the concensus of opinion on this and other forums leads to think that 70K seems to be a reasonable life expectancy, but I agree with James. Dont leave it to chance. regular checks are the key, as the alternative can be very expensive, to say the least.

That's my theory! It depends how well you can pick up on faults and the way the car drives tbh, the reason people recommend 70k is that that appears average some go well before. I guess if you cannot tell by feel or can't do the tests you should either pay someone to do it, or do as advised treat it as a service item, cos if you can't or don't, pick up on it failing it will get expensive! I know from experience on different makes and models what seizing VCUs, LSDs etc feel like, and having a freelander that's just started doing it its pretty obvious to me! But may not be to you! So you need to decide the best course of action for you, just bear in mind it'll be an expensive mistake if you miss the signs!

:hurt: think i'm going to have to order a new vcu & get my hands dirty love to go to bell, a bit to far from me, do have a local lr specialist as i said, but only one review on the sight, & they have been there a good 2/3 years, dos'nt bode well me thinks, thanks guys, gonna have to have a serious think nowThat's my theory!

Changed my VCU at 103,000 miles, no visible defect just based on mileage. Once you start reading all the VCU problem threads you can convince yourself that if yours hasn't failed yet and taken out the IRD and diff then it soon will. What price peace of mind, £275 seems quite reasonable especially from a well respected supplier (Bell). I am also a firm believer in planned maintenance and not maintenance by defect as being stuck on the back of a recovery vehicle is not my idea of fun

Mines only done 64k and it's just started showing up. Shows the variation in mileages

See my simple torque wrench test under VCU on the sticky - good go - nogo test I think.

rear wheel is better ,measure the resistance taken to turn wheel slowly
Ha ha just tried reading the vcu sticky, is it 10 pages of slanging match lol? So I need a torque wrench, check, 1.2 meter bar, check, set it to 9 nm and see if it will turn the rear wheel from 12 o'clock to 3 o'clock. It shouldnt go past 3 o'clock? If it does vcu fooked? If it don't move at all vcu fooked?
Correct?
Correct?

more like andyfrelander ,i would use just use a torque wrench to turn wheel ,there is no limit to how far you turn it , it will or should stiffen/lock if you try to move wheel too fast but should turn slowly with even pull if you measure its lightest pull needed to turn it you could post results

viscous has a standing resistance ,but stiffens and locks as the difference in speed between both sides of it increase , so in normal drivng the difference shouldnt be enough and should act like a differential ,full lock has the greatest speed differential and 4 wheels that have grip ,some wind up is normal with a vc in tight turns as is noticeable if you turn into gravel drive with rrs as well ,its just if vc is too stiff or locked this wind up may increase rather than disappating through movement of vc
