What happens when the viscous coupling and IRD are shot on a Freelander?

I know how much it will cost to fix it all I need to know is what will happen if they completely fail? Is it safe to drive?What happens when the viscous coupling and IRD are shot on a Freelander?
It is usually failure of the viscous coupling which causes problems with the IRD, and more often than not, the rear differential or its mounts.





While the VC is faulty (I'm presuming it's seized?) it will continue to wear out the IRD.





The temporary fix to save further damage to the diff and IRD is to remove both propshafts; you then have a 2wd fwd vehicle - they actually work quite well in this form!





Good luck.What happens when the viscous coupling and IRD are shot on a Freelander?
Its unlikely that both the viscus and IRD have failed on your freelander at the same time. If the IRD fails then you will loose drive, there is no diff lock feature of the IRD fitted to freelander.





If the viscus it as fault and is damaged then there could be a serious safety issue here. If the viscus failed and broke up, the prop shafts it connects could seperate and potentially and at worse case flip the car. Obiously this is unlikely but it is possible. Also it could smash its way through the floor. Again unlikely but still possible.
Continuing to drive it could damage other parts, resulting in a more expensive repair. If the viscous coupling suddenly violently fails, or if a minor vibration turns into a major vibration, it could rip the driveline out.
my ird failed striped nearly all the teeth and the bearings broke up so i lost drive on the motorway!! it cost 拢180 for a second hand replacement and 拢200 to fit it and every body said that was cheep. get rid of it quick.
