As per title.
When reversing, on full right lock (not tried it on left lock), there is a definite feeling of something binding up, the same sensation is there after straightening up forwards and not there after reversing again. My head is telling me it's the front diff on its way out. Is there any way of testing or checking for diff failure? It wasn't me! |

You've not bought a Freelander have you Ozzy? It's not the centre diff dropping in, might happen if the linkage hasn't got enough free play. It might be the handbrake shoes dragging, or it might be that when on full lock in reverse your tyres are rubbing with the slight movement of the suspension as you are dragging the front axle.

One wheel up, will not turn. Both wheels up, spin one, prop turns but not the other wheel. Spin the other, and the same thing. It wasn't me!

......and spinning the prop by hand causes both wheels to turn in the same direction. It wasn't me!

Ok, that is exceptionally weird!
What happens if you lock the centre diff and, with both front wheels off the ground, try rotating one wheel? I don't at the moment see any reason why with one wheel in the air you cannot rotate it, but with both you can without the other moving! I presume it is a standard diff not an ATB or LSD? |

When the single wheel was lifted, it span about a quarter of a turn.
Standard diff. I'll go and try with the diff locked now. It wasn't me! |

Okay, false flag on the single wheel not turning. That turns out to be the diff lock not disengaging or engaging properly, it's only got about 3/4 of it's designed sweep. It engages and disengages properly by hand though.
I've still got the same symptoms with both wheels in the air. With the centre diff locked, neither wheel will turn. So, pooped diff? And CDL lever/linkage needing a tweek? It wasn't me! |

Are you sure that with both wheels in the air, only the one you were rotating was moving. Everything else you've described is consistent with a failed diff, but not this! |

Yup. Spin the prop, and both wheels turn in the same direction. It wasn't me!

The results you're reporting seem inconsistent. If everything is working correctly then:
1. Jacking one wheel and rotating it will turn the propshaft. This is causing the differential gears and the crownwheel and pinion to rotate. If the differential has broken then generally you won't be able to turn the wheel (because it's locked to the other wheel by the broken diff). 2. If you lock the centre diff and jack up both wheels, then the propshaft cannot turn of course, so rotating one front wheel with a good diff will cause the other wheel to rotate in the opposite direction (the crownwheel and pinion are locked by the propshaft but the differential gears will transmit the motion of one wheel into a reverse motion of the other). If the diff has failed you won't be able to turn either wheel. The only situation I can match to your results is that your diff is on the point of failure and sometimes locks and sometimes doesn't. I do think it would be advisable to drop the diff out and check asap, before using the vehicle any more. A front diff failure is dangerous and may well cause loss of control. The front diff on my DC failed in this way (it's an 07 and had the early two-gear diff) and more or less instantly it became virtually impossible to steer. Quite disturbing, and with almost no warning. |

have you been off road recently?
any TC lights coming on or ABS noises? so one wheel up, with CDL not engaged and it turns or not? just trying to clarify. Cheers James 110 2010 XS Utility 130 2011 M57 bespoke Camper 90 2010 Hardtop 90 M57 1988 Hardtop |

If it's only one wheel maybe the brake has seized on?

Now I know to move the CDL linkage to fully engage/disengage it, yes one wheel up CDL off - wheel and prop turn. CDL on, no turning of prop or wheel. This is the same with either wheel.
Both wheels up, CDL works as it should, ie neither wheel turns. There are no lights on the dash indicating an abs/tc fault. Yes it has been off road, however these symptoms have been present since I've had the vehicle - approx four months. It wasn't me! |
