I took my 110 Defender TD5 off road (for the first time) on some pretty muddy hilly sections. On a couple of muddy rutted up-hill sections I got in to trouble, lost traction and had to reverse and have another go. I tried with and with out diff lock which seemed to make no difference. When I select diff lock on, the warning light comes on if I hold the selector hard left. It goes off as soon as I loose it and stays off. So after all that rambling the question is, how do I actually know the diff lock is working?
 
The light should stay on. I don't think you are selecting correctly. Sometimes you may need to go into neutral, take your foot off the clutch then try to select d/l / low again ?
 
to make sure get somebody to watch wile u go up the hill again. at least 2 wheels should be turning. if only one is spinning then it isnt engaged
 
you should have gearbox in neutral, clutch engaged & be near enough stationary when selecting any part of the transfer box, otherwise you'll mash it.
if you're already doing this, check the cable...if it still doesnt work, search all forums for "diff Lock"...loads of threads

check what cable ?
 
Diff lock should just slide to the left whatever position the box is in, to see if it's locking up lift one wheel and try to spin it, if it doesn't spin the diff is locked...

Sounds like your linkage might be sloppy, get under and have a quick look - the linkage pins wear and give these symptoms.

que?

Diff lock can be selected at any speed as long as all wheels are turning at the same speed... Hi/Lo can be changed on the move below 20mph (IIRC)
 
The diff lock light switch mechanism is designed such that the diff lock light only comes on when the diff lock actually engages. The light has nothing to do with the lever moving left or right.

You should tell some one to watch it and when the diff lock is engaged one wheel from EACH AXLE shoud be turning. If they are it means center diff is locked.
 
really? would that not start wind up? thought it was if turning at different speeds, eg loose surface?

No, if wheels are turning at different speeds - thats when you'll fook up your transfer box by sticking it into difflock...

You can be absolutely stationary and have a wheel spinning and sticking the diff lock on then would most likely cause damage, but if you're driving up to an obstacle that looks dodgy, just sliding the knob across to the left will lock the diff before it starts diffing!
 
HAHA basically if the light is on its in lol. Try messing about with the clutch and dving forward slowly while forcing it over to the left. Sometimes without use they get a bit temperamental. As said the centre diff will only lock the 2 axles together so the only real way to test it is to get all wheels off the ground but if the light wasn't on then it more than likely wasn't selected. Have a look at the linkage.
