Anyone has any experience or can share your knowledge on this? Thanks

Crap
Id be changing work shops what a load of bull ****

Was that an April 1 joke. You could say that about any vehicle. I comes down to how and where you drive it. A locker will get you through places the manufacturers never intended the car to travel.

Hi

I think he is sort of right actually. Just not expressed correctly. Nor in the context of how the vehicle may be used..

The rover rear diff is known to have too small bearings too close together and this leads to a CW&P that does separate under high shock loads during HD 4wding.

The normal fix is to 'peg' the diff - welding in plates and fitting a pin to limit crown wheel deflection so preventing pinion/crown wheel teeth separating too far leading to very high tooth loads and so destruction.

Some go further and install thicker HD CW&P from Ashcroft.

That said the rover diff while weaker than many on the market is fine for reasonable use with standard size tyres even with a locker.

Remembering that the throttle does work both ways can save a lot of money in 4wding.
