Freelander 2 (LR2) Haldex unit.

I have a Freelander 1 and know that during the MOT brake test, a wheel on the untested axle should be allowed to spin so as not to cause transmission wind up and damage to the transmission.
Is the same true for the Freelander 2 with the Haldex diff?

If one or both rears weren’t allowed to spin I’d of thought the front wouldn’t spin far before stopping.

Dunno about the F2, but I believe most Haldex cars you can switch into 2WD.

Whether the switch would work on a Land Rover is another matter!

are switches meant to work on landrovers .or should that be
are landrovers meant to work. lol

Bit of both really.

Thinking about it, on an F2 switching between 4 Lock, 4 on demand and 2WD is probably wrapped up in "Terrain Response".

mine does not have terrain response,it is just the s model,

LR did that with the D3 too. Basically the best part of the LR 4WD system wasn't supplied with the base model vehicles. All a bit pointless really imo.

The s model FL2 does have terrain response monitoring for wheel slip etc but it doesn't have the dial which allows you to select the special programs like grass gravel snow, sand, mud ruts.

I assume they removed it on principle they were selling the s model cheaper than the next model up (gs) which has the full system. It's still a very capable vehicle oft road if it's only a s model.

ref the mot, dont they put a special brake testing box onto the seat and take it for a road test if they haven’t got a suitable 4x4 rolling road tester

Yes. It's called a Tapley meter. Full description is a decellerometer. They use it to measure how good the brakes are when they don't have the facitiy to allow all 4 wheels to turn on rollers. It gives an indication of brake performance. Still allowed and still used today int UK for mot testing. Normally sits int floor at my local not tester as they're heavy.

To answer the op's question...

The haldex should only enable when yer first pull away (then release) or if yer FL2 detects it needs 4x4 (if in normal driving mode and yer haven't selected one of the special terrain response programs which may permantly engae it). Yer right to be concerned. But mot testers should know about 4x4's regardless of the type.

Most mot'ers have one set of rollers for one axle testing at a time. This shouldn't be used for a Freelander 1 or 2 if the props etc are fitted if the rollers only travel in the same direction. If the rollers will allow travel in opposite directions then it is ok, as the tested wheel goes forward and the other wheel on the same axle can go backwards due to the differentual between the axle pair wheels. The props won't turn. Not many mot'ers have this setup so they will use the Tapley meter instead.

Some mot'ers have a full 4 wheel roller setup which allows all 4 wheels to turn. The rollers need to adjust position to allow for differing wheelbase distance between axles. Even fewer mot'ers have this setup as it's not needed and very eggspensive. It's not mandatory so they won't buy the kit. The rollers on an axle will allow wheels to turn in opposite direction across axle pairs.

Roller testing is the better test as yer can test individual wheels for brake efficiency. Yer get to know if all brakes are working indivually as opposed to the Tapley method which tells you the vehicle as a hole has stopped and by a value measured.

If it were me then I would find a typical mot'er with one roller setup for one axle only. They will use the Tapley meter. This will be the vast majority of mot'ers I would guess.

The rear wheels should turn in opposite direction on a Freelander 1 or 2 if yer lift the rear end and spin one of them.

When I refers to axles... I knows freelanders dun't have axles because they're betterer but it makes the explanation easier.
