--- Quote from: "doris" ---Hi All

I have the same problem, only with low range, and have the shed booked in for a recon t box.

I have heard of this grub screw, but haven't been able to find it..........  but then I am fairly pants at nuts and bolts and the like.

Can anyone explain in words of few syllables how to find this fabled grub screw and how to fix it please??

Pictures would of course be great too?

Much Thanks

Damon

right
remove the gear sticks and peel the rubber cover off
now remove the plastic center console
you should now be faced with a alloy cover with pop rivits around it holding it down drill the poprivits out and remove the cover
you can now see the transfere box and maint gearbox
ontop of the transfer box there is a rectangle alloy casing where the selector arm goes to
its bolted down by 6 (afink) 13mm hex head m8 bolts
u need to undo these o and the 14mm breather union, and the linkage itself
and then you can remove the housing
inside the housing on the selector shaft at the end is a arm on the arm there is a 6mm alan key grub screw, and thats the f***** that backs itself off so often
but 1st what exactly is the problem with your box ? secribe in full maybe we can help out and its something simple, as lt230's dont really go wrong, ive just blown 1 center diff up  :oops:

Well.......  it has jumped out of low range every now and again for ever.  Lever will not move sideways to engage diff lock....... imagine its the linkage seized, but lots of WD40 and BFH hasn't shifted it.  

But just recently it has been getting whinier on overun, and now it will not hold high range (pops out on decel) and low range has just disappeared.  The lever goes way  forward and way back in a very sloppy fashion, but there is nothing at the low range end.....  it does feel like there is a very slight 'click' as the lever approaches the radio, but there is no drive.  There is drive in high, but the lever has to be all the way back (with the gate removed) before it engages.

At the mo I have stripped out the sound deadening foam, and removed the rubber gaiter and the gate around the lever, and it is held in high with a big bungee around the rear of the centre console.  I have researched it a bit, and have been looking for this grub screw, but didn't realise it was under the lever housing mechanism.

ill take some piccys of a transfer box for u tomorra and flirt the housing off and show you what your looking at
whining they all do, just more evident without sound proofing  :lol: , its just a land rover  :shock:
change the oil in the box see what comes out
as for the sloppy lever yes that be the grub screw
difflock if it aint been used for a while itll be siezed so u need get underneath with a whackometer  :lol:  (hammer) and nock it into difflock
