Sorry, can't agree on this - if the axle can go lower than the factory spring extension limit, the axle will move further towards the sump - simple geometry (the panhard rod moves in an arc - as the axle end moves down relative to the chassis, it also moves sideways relative to the chassis - how far is limited by the shock absorber extension limit on the side opposite the steering box). If, at the same time, the right spring is fully drooped and the left is fully compressed, the diff and prop shaft will be closer to the sump.Originally Posted by rick130

Yea, but when the suspension is returned to original height, it has no bearing on the postion, it returns back to normal, the panhard is a fixed item and doesn't change lenght.................they've screwed the sump design
YarnMaster
it doesnt change length, but due to the design, it will move the diff from side to side with suspension travel
OldBushie
Of course it does
But when its at standard height and in its original arc, the diff is in the same position, as in, if the front diff was in its standard limits of travel, even with a lift as the shocks were pobably not longer than factory, it can only be in the same position achievable before
Hence it can't be a fault of the lift
YarnMaster
you're still assuming they used the stock shocks with the suspension lift....... lets just toy with the idea that they didnt
ForumSage
No, I think we're all clear that it could droop further. But the difference it makes is minor.
The panhard on my rangie measures roughly 85cm, if the axle drops by 200mm from the bar being horizontal then it moves sideways only 2.5cm.
If it drops 300mm from horizontal it moves sideways only 5.5cm.
Not quite sure what numbers you're expecting, but that's not much.
OldBushie
as it drops it moves down below the sump........

LR have released a bulletin on this problem. It was originally issued for a specific market but has been revised to a general bulletin.
The fix is a revised sump.
It must be a very rare occurance. We haven't seen a problem on the cars through here (and that includes a few Press Cars).

Still wont make a lick of difference
LR have ****ed up
