Is that the model with the HALDEX abortion?My customers gift from her freelander 2 is a rumbling rear diff and a blown front diff... Happy effing Christmas from landrover
Tis indeed Keith. Technically an awd not 4wd.. The rear diff is unbelievably priced over here along with the front diff

Unusual for both to go at the same time. Tis a 4wd. The driver can't deselect 4wd when its active so its full time transmission.My customers gift from her freelander 2 is a rumbling rear diff and a blown front diff... Happy effing Christmas from landrover
Lucky she int got air suspension and a snapped crank anorl.

It all depends on how much hair lacquer is on board and how it's loaded.HALDEX, another abortion using slipping clutches to apportion the torque front to rear and eliminate the need for a center diff

The lady drives it quickly but her husband damages every car they have owned
.So is it supposed to be in 4wd all the time or not?
Part time 4wd or part-time 2wd is not full time 4wd if it's selectable surely Shirley

It's not full time 4WD but then full time 4WD is pretty pointless for every day use IMO. I much preferred selectable 4WD on my previous 4 X 4's.The front diff isn't turning the prop and the back diff has a rumble when turned

Both the FL1 and FL2 are considered full time transmission as the driver can't choose to disconnect 4x4 when it's activated. They both run as front wheel drive until 4x4 activates. The driver can't choose to disable it when it wants to activate - which is why LR quote it as full time transmission. It is, but not all the time. You don't always know when that will be. I can see why this annoys peeps in the description of what happens. The FL1 uses a vcu and the FL2 a haldex. You can disconnect drive to the rear wheels by pulling out the fuse powering the haldex setup on the FL2 which is helpful for diagnostics. It will then run as front wheel drive only.The front diff isn't turning the prop and the back diff has a rumble when turned

The FL2 applies power initially to the rear wheels when first pulling away, breifly, to reduce wheel spin. It automatically applies power to the rear wheels in normal driving mode when it detects it needs it for betterer traction (wheel spin etc). Terrain responce will apply it all the time, with different setups of traction control sensiitivity.
The FL2 rear diff, front bearing can fail. There's a stronger bearing fitted to the later haldex 4. When either the rear diff or haldex fail, it's not uncommon for the other to fail. Peeps forget to change the fluid and filter in the haldex which is the cause of most problems. The filter gets blocked and the pump fails. It's bad luck to have problems at the front and rear. Some owners keep going regardelss of a rumble, until it stops working.

Thanks for the explanation. On some cars with a similar set up, it's possible to manually select 2WD or 4WD.
You've got to hand it to them, all cars are full time transmission as long as they're in gear. VCU is full time 4x4 occasionally locked front to rear and haldex is full time FWD occasionally 4x4.

which is why LR quote it as full time transmission and are careful not to misrepresent as a 4WD or 4x4, only insinuate
