disco tony Posted June 21, 2007 Share Posted June 21, 2007 I have been reading several threads on here about diff locks. I am now confused. I had trouble with diff lock on my 110, I was told back then to jack up one wheel and try to spin it with diff lock (DL) engaged, if wheel spins, DL shot, fine. Stu 666 recently suspected he had a problem with his DL so spoke to a garage, (LR specialist {independant}) about it, he said that the DL ONLY locks front to rear axles, thus two corners still had the potential to spin? If this IS the case, why do we get concerned with axle wind up? If this isnt the case, why do people spend a fortune on ARB or DETROIT lockers? Can somebody please satisfy my curiosity?

Tony The standard Land Rover difflock operates between the front and rear propshafts (it is inside the transfer case) and it does only lock the front to rear axles and (due to the differential in each axle) you can easily get one wheel per axle spinning while the other sits doing nothing. This is why people spend loads on lockers or LSDs - once you have lockers then you have to get all four wheels spinning before you lose traction. A normal car (or Land Rover with difflock disengaged) only has to spin one wheel to lose most of it's drive. A Land Rover with (centre) difflock engaged has to spin two wheels (one on each axle) to lose most of it's drive. A Land Rover with (centre) difflock engaged and axle lockers engaged has to spin four wheels to lose most of it's drive. Now - wind-up: With the central diff locked, wind-up is due to the front wheels traveling further when going around corners than the back wheels. ie It's front-to-back wind-up instead of side-to-side. If you drive on a grippy surface with the centre diff locked you will experience premature drivetrain component wear and heavy steering - and maybe other handling related symptoms. Hope this helps.

disco tony Posted June 22, 2007 Author Share Posted June 22, 2007 Thanks two sheds, that explains it properly, and also explains some slippery situations weve got into during some of our trips! Thanks Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted June 23, 2007 Share Posted June 23, 2007 And on some early Disco IIs the difflock is fitted but the actuating levers are not, and on some the actuating mechanism inside the LT230 is also missing. Luckily LR came to their senses and resurrected the difflock in (I think) 2003 or 4. Check on this when buying a DII (unless it is only to be used on the school and supermarket run).
