do all disco td5's have a manual select for the diff lock ?

my 52 reg does but my mates t reg doesn't seem to, or so the picture on the centre consoles would have us think.

i guess the linkage on mine is seized as it wont budge over to the left but nor will daves. we can both select high and low no probs.

the only other difference is mines an auto box, his is manual.
 
It's only there if it's on the transfer leaver. otherwise you got electronic traction control.:D
 
so it looks like my mates t reg is electronic and my 52 reg is manual.
thanks for the replies.
 
saying that though the levers are identical and feel the same when you try and push to the left.
the only give away was the sticker on the centre console.
would a dealer have a list of those with as we haven't ruled out an incorrect sticker yet.

They all have electronic traction control. The sticker on the console will tell you if you have the optional diff-lock or not. Most don't.

Various options for retro-fitting, but its probably only viable if you have the guts in the transfer box and only need to fit a linkage.
Discoparts do a solenoid kit and you can always buy the proper linkage from the stealer or some gearbox specialists.
The tell-tale for the guts being present is apparently a 'nipple' at the top of the transfer box. You need to crawl under and have double-jointed arms to find it. Do a search on this site as its been discussed before.
 
the difflock is still in the transfere box regardless
just is the linkage arm was removed as land rover thought diff lock wasnt nessicary in their new revised model discovery !! until they had enquirerys about it and thus diff lock was re-enstated on the 2000 models and some 99 models
you can get retro fit parts for the difflock from www.ashcrofttransmissions.co.uk
or give him a ring and ask for dave very good people

have searched the internet high and low for an answer to this question.
here goes

The locking centre differential was still fitted, although the linkage to operate it was not attached, as Land Rover believed that the traction control and newly-developed Hill Descent Control would render it redundant. In 2002, US models saw the mechanism itself finally removed. At this time the mechanism was removed on European 02 Model Year vehicles and remained fully deleted until the face-lifted model was introduced later in that year.



Facelifted Land Rover Discovery Series II



Customer demand saw the mechanism and controls fully reinstated as a cost option only (standard on top of range HSE/ES vehicles) on UK/Irish models.


with this in mind i contacted williams landrover in manchester.
they confirmed that the cost option included the needed linkage to be connected. no cost no linkage, no manual diff lock.


so in short they are either manual or not operational at all.
when asked about the sticker on the centre console the reply was "it is cheaper to supply and fit one set of stickers."
 
In my limited knowledge, the electronic traction control as fitted to the S2 discos negated the need for a manual difflock, with the electronics kicking it in and out when it sensed the need. That was great until it was discovered that there were times when you needed it to work and it didnt, or it didnt work properly, so in the S2a (facelifted S2) they put the manual difflock back in to solve the problem.
Mine has the electronic selection and I got an aweful grinding sound as the difflock was trying to engage as I crossed a deep but narrow creek bed and lost traction to one wheel only that spun very fast... I thought the box was going to fall out.
I am lead to believe that when you select low range, that automatically electronically locks the diff, but dont bet the house on that, it's only heresay.

this was the case but it was only standard on the top of the range.
according to l/r over here, the internal workings are still in place for the facelift, but the linkage was removed only to be replace as an optional extra.

your comment on electronically selected on low range would also make sense, as you can purchase solenoid kits as after market fits.
 
This is taken from the Ashcroft Transmissions site - with acknowledgements of course

If you have the diff lock stud on your unit you will only require the linkage parts, to determine this you will need to find the transfer case serial number and check it starts with either 41D or 42D.

If it starts 61D, 62D, 69D or 70D then you will need the diff lock parts to go in the transfer case which are an additional £ 175.
Suggests the internals are not always present
 
Not sure if this will help....

Edited to add-----looking at it in more depth it probably doesnt, but I might as well leave it there as someone might find it interesting

breakdown of the vin did come in handy outbackjack, but not for the diff lock unfortunately.
i have now learnt that mine is a td5 egr/cat built iin 2003 in that special place in the middle of the country, where everyone goes on holiday called solihull :eek:

maybe thats why my other mate likes them so much, they speak the same language :) lovfl
