Hi all, been reading about faulty diffs. Went out jacked up rear nearside wheel, turned wheel by hand turned quitèabit, very clunky , noticed lot of play where shaft enters diff. Should I be worried!

All diffs are frightening when jacked up and the wheel rotated by hand, your worry is grinding, rumbling and sounds like a lorry in low gear struggling, if that is not happening keep driving and enjoy  my PC is slightly to the right of Genghis

Cheers dartman, felt slight vibration , more In higher gears, am I right in thinking back wheels dont drive till terrain response is engaged

Thanks for info pab, when jacked up dri eshafts goi g into rear diff feel very sla k and clunky! Its a 58 plate 90k maybe take it to lr have them look at it. Had a disco1 before fl2 ,was easy to work on fl2 not so easy , getting old!

I understood the Freelander never drops below 10% on the rear, or is that only later versions? my PC is slightly to the right of Genghis

The LR docs don't seem to specify a minimum torque transfer explicitly, but they make various references to no torque transfer or torque dropping to zero for both Gen 3 and Gen 4 Haldex. Thus, I think that torque transfer can be zero (or as close to it as makes no difference) for all FL2s whatever their Haldex gen or MY.

assuming no speed differential across the haldex? Otherwise the swash system on gen3 would activate?

The swash system in the Gen 3 drives the hydraulic pump and generates the hydraulic pressure (Gen 4 uses an electric pump), but the control module and control valving will ultimately determine whether that pressure gets to the clutch plates. But, of course, a speed differential across the Haldex is exactly when the Haldex will engage, in pretty much any mode and circumstances.
