Hello,

Juddering from the rear.... on hard acceleration. 08 freelander 2 diesel auto. The fault was lost on wheel balancing which has now been rectified. Nothing through the steering wheel now, just juddering from rear..... and now worried its something serious

It's not unheard of for the Haldex to stick on. When was theHaldex fluid and filter changed last?

I have no traceable history... and even worse I have no idea what you mean. But sounds like I should get this done. I take it as the differential? Basic job and price? Thanks for your input

The Haldex is the electromechanical drive coupling to the rear. If the fluid breaks down, or the filter blocks, then the pump motor can overheat, and fail, or the pressure doesn't bleed down after activation, which causes binding and again failure.
The Haldex fluid and all other transmission component fluids should really be changed at 50k miles intervals, although it seldom is, as LR say 150k miles or 10 years for these fluids.
Not doing the Haldex fluid and filter effectively shortens the life of the Haldex unit (which is seriously expensive to replace). The fluid and filter can be bought for under £60, and it takes under an hour to do.
I'd have the Haldex fluid and filter changed first, and if it solves the issue, then have all the other fluids changed too, as all will be well past it.
If the Haldex still sticks after a fluid/filter change, then a reconditioned replacement will be needed.
