4pin diff were fitted to rear 4.6 to cope with the torque and then others willy nilly on the run out p38 as what ever was in the bin at time

Power is split 50/50, however the rear has slightly less weight on the wheels so maybe they spin more easily making the TC on the rear work harder.
For sure if my diffs fail I will be fitting a LSD as replacements
The rear diff takes more weight than the front one when pulling away with an heavy load.

I know about the randomisation of diffs fitted depending on what they had laying around - but I always thought Thor 4.6s were supposed to have four pin diffs front and rear due to the standard fit 4 wheel TC.
That was my assumption. To be fair I seem to remember a thread where someone else assumed that and it turned out his Thor only had a 2 pin diff on the front. The problem with these motors is that you never know who has done "a cheap fix" on it before you get it.

usually with 4wd system rear has greater weight when you set off or pull hard as the opposite effect of driving the wheel forward is trying to lift car front up
That makes sense. Would the front diffs not work harder seeing as the steering is happening on that axle?

Indeed, wouldn't the more planted axle be less likely to have spinning wheels scrabbling for grip putting the diff under strain?

Hi guys I've now got a wheel brace and my wheel does not turn
I've jacked up the car
Put the hand brake on
Put it in neutral
And the wheel doesn't turn

So the VCU is seized. Need to replace it ASAP before it shredds a diff.
You do realise that the wheel will only turn very slowly?

I will try again but it moved a little about an inch or two then stopped

That's the back lash in the drive line, when it stops just exert continuous pressure and it should continue to move very slowly.

Ok will try again but I was using a load of pressure before
Sadly whilst it can cause other problems and is best changed ASAP it is not the cause of your loss of traction. Think you mentioned being stuck and the front wheels spinning. It is not possible to spin just the front wheels at least one of the rear wheels would also be spinning. That should cause TC to trip in with a lot of clicking. Wheel should turn VERY slowly with moderate pressure applied to wheel brace.

an rtc6044 , it sits in the housing directly behind front prop flange, you an change it with box in situ
Any of these take your pick. http://www.island-4x4.co.uk/advanced_search_result.php?keywords=rtc6044&x=28&y=10

Ow bloody hell. Anyone want to buy a Range Rover.
What will happen if I leave it for a while
Considering I don't use it every day and only use it for the bees once every other week
