diif lock inquiry

okay so when you people lock the center in (high lock) do you just push the diff lock lever over to the left? or do you go up thru nuetral and back down into lock? I have thought about this some and just wondered I always go to N then down into lock. or up for LL.

I just give it a little push and it locks right in no neutral. Sometimes I let it roll while shifting the lever to make it easier.

Yes as long as you are moving very slowly (like you are just about to stop). This is what the owners manual says.

You can lock at any speed as long as you are not spinning a wheel. There is no need to be travelling really slowly.

To lazy to type the entier page out of the manual but here is what it says

In and out of LOCK: Hi unlock to hi lock or lo unlock to low lock can be made while vehical is traveling in a straight line witout wheel spin or when stationary.

But to shift from High to Low or Low to high: as long as you are moving very slowly less then 5 mph

Actually, yes I do think so.....

Probably 50 km/h (30 mph). It is no problem. As stated above, straight line, no wheel spin. I wouldn't do it at high speed (just in case) but you certainly don't need to be moving very slowly.

First lets make sure we are talking about the same thing--going from high to low gears is ONLY done at low speeds.

O.K.

Locking the center diff can be done, well, pretty much any speed. I have done it at highway speeds when going skiing in Colorado and passing through the Eisenhauer Tunnel and all of a sudden there is snow. There should be no reason this would not work as long as you are going straight and not slipping a wheel. I have been doing this for years, never a failure. All my manuals on all my 4wd's say this is cool.

cool. well i think the reason i thought you had to be going slow to lock the center is because on the disco I's they got that little thing in fronta the diff lock lever that emphasises the 0-5 to lock.

My apologies

Changing from hi to lo only when going slowand vice versa.
Sticking the diff lock in but not changing ratio can be done at any speed provided there's no wheel spin and you're not hacking round a sharp bend.
Better to put the diff lock in before it's needed like a big snowy bend on the road than struggle to twirl the steering wheel and try and move the difflock lever as everything's going pearshaped.
I've been doing it that way for years.
Hitting the difflock just slides a sort of dog clutch and locks the diff action.
Bad if there is a differential speed between the front and rear axles but coolin other conditions.

Having attended an off roading course run by land Rover I can attest that there is no prolem chnging from low to high on the move as long as you match the engine to road speed Ok - just like normal gear changing only it is more critical. No need to stop at all. In a manual anyway. Need to use the clutch correctly too - I can't really remember what order - just instinctive now. One guy on the course (in a 110 TDi - we took turns) just could not get the hang of it - eventually out of sympathy for the gear box the instructor gave up with him. I guess I am usually at around 20 mph max when I do this. I dont go from high to low on the move, though i dont see why not possible. Diff lock makes no odds. sometimes it sticks and you need to drive backwards to release it.

I equate that to 2wd->4wd in a parttime system. I did that on-the-fly all the time before. I continue to do it on-the-fly on highway when necessary with the full-time 4wd.

Catch - no pressure on the driveline. IE, ease up on the accelerator so there is no power going to the wheels when you do this.

Going from Hi to Lo - different story!

Double de-clutching helps with the lo-hi gearchange.
Better to use low box if pulling away up hill with a really heavy trailer then change carefully up into hi box.
