Thats a £ 450 - 500 job too (new/recon centre VC + labour)
We do an uprated centre VC for £175.00+VAT exchange
There's an interesting side issue here, regarding how 4wd rolling roads actually work. I'm assuming the roller pairs are independent, as the applied torque will be different front and rear (although speed must be the same)..., and hence why they can tell that the centre VC is knackered..
But how are the rollers loaded? does the operator have to load them up progressively in relation to each other, whilst maintaining the same speed on each?
Surely they can't rely on the centre VC to equalise the speeds on the roller pairs?? But if that's the case, then what does it matter if the VC is faulty?...

This is an interesting anomoly.
I have had people bring supposedly knackered centre VCs in for rebuild/uprate because of this very issue. You take the thing apart and find nothing wrong
Has me thinking that maybe some r/roads bring the load up the same on both sets of rollers, and with the already discussed torque bias in the transfer, you will simply stop the front wheels, maybe.........
