Assume nothing ! The IRD has to come off but what did they put on the worksheet??

Hi,
There is no way to know if the oil was changed. when the clutch was done.
You can do the clutch without removing the IRD ... so you don't need to renew the IRD oil.

If you take it off and don't tilt it too much most of the oil stays in, then top up. Did you pay for IRD oil? If not then assume not done!
Thankyou the clutch was changed before i got the vehicle and no mention of iRD

You need to remove fill plug before the drain plug if you don't want to get stuck with an empty IRD.
You can easily find a compatible oil for the IRD compared to the TD4 gearbox.

If the car has different tires with uneven wear or the VCU is too stiff the IRD is more likely to fail than because of an oil issue.
Check you have 4 tires all the same.
If the VCU is to stiff, VCU bearing and universal joints should break before the IRD, and the read Diff.

May I ask a possibly silly question? what would happen if back tyres were different to the front?- mine are all the same. The complete prop I have got hold off is in good condition with new bearings either side of vcu it came off of a vehicle with an electrical fault that could not be cured. so I could in theory push my luck and bolt the complete prop straight on?

Odd tyres should be avoided, as different tyres have different rolling radii. If the rolling difference between front and rear is too much, then the VCU can start to transfer torque, which loads up the IRD and diff unnecessarily, resulting in rapid wear and failure.
Ah I see thankyou.

Have a read of this...

The brakes were obviously not on, the transmission was fighting the VCU because of different diameter tyres - there's only 1 loser in that fight... the IRD by a knock out.
