Thread: Engaging 4WD High/Low

When you go into low range the yellow knob is supposed to pop back up

you can just engage low range with the red lever though.

You sound a little confused here.

The yellow knob is to engage four wheel drive while in High Range.

To disengage four wheel drive in High Range, you need to stop select Low Range by pulling the lever with the red knob to the rear, as soon as you do this the yellow knob will pop up, then select High Range by moving the red knob forward.

In Low Range your Series Land Rover* is always in four wheel drive.

Thanks Diana and Pheonix,

Seems I was just a little confused. I was going by the plate that states only how to engage high range. My thought was the yellow knob was to engage 4wd low and high, however this seems not the case.

Thanks for clearing that up and seems its all working as it should, which is good news in terms of my list of things to fix .

Cheers, Josh

I love to see a colour co-ordinated response

So, Lotz-a-Landies, Diana,..........I'm to understand from all this, that ,whilst driving along in High Range 2wd, ....4wd can be engaged by pressing down on the yellow knob, but then 4wd can't be disengaged by trying to pull up the yellow knob, without changing down to low range either by skillful doubledeclutching with the perfect revs, or (more safely), stopping, going to low ,when the yellow knob automatically pops up,........then move to high range in 2wd,
Correct?...........(I'm a new owner novice as well)

Cheers Pete

Yes, you can not get out of 4wd by pulling up the yellow one, it's locked down. However you don't have to put the red knob all the way into gear to get the yellow knob to pop back up. I'm not 100% sure if that means that you are out of 4wd, but i'm pretty sure it is

Yes, once the yellow knob pops up, front drive will disengage when the red lever is moved forward*.

Just a word of caution - if you have free wheeling front hubs, do not engage four wheel drive while moving unless they are locked.

* Actually, the situation when the red lever is moved forward is that pressure is on a spring to disengage the drive. If there is a lot of pressure on the teeth of the dog, for example, if you have a lot of windup due to driving on a hard surface, it may not immediately disengage, and the same may happen if the selector shafts are rusty and do not move freely.

if your tcase is in orginal order and as per specs you must engage low range before the hi-range knob will pop up and it should do this by itself thanks to the spring you can see underneath it pushing on the tunnel cover.

you can mod the case so that the yellow knob can pop up as soon as you hit nuetral so you dont have to do the stop to go into low thing. but more often than not you wont have a reason to and the series rover being the speed deamon that it is your friends wont notice that youve stopped to do the hilohi shuffle to get out of 4 hi.
