Front wheels “hopping” in full lock

[Dezzy]

It's deffo a 4x4 thing. Not sure if its the front diff not letting the outside wheel to spin fast enough or the centre diff not allowing enough slip between axles.
Series Land Rover's are really bad for it in low box. Coming out of a field onto tarmac still in low range and they'll almost bounce on full lock. Ok in the mud as the wheels can all slip to suit.
