bigpike Posted January 27, 2008 Share Posted January 27, 2008 being a newbie to landrovers im not sure how the transmision works . i have a 1988 90 3.5 v8 csw . i was having a thrash around the orchard today without the centre diff locked i noticed from a standing start it seemed to be more front wheel drive than rear . i expected it to drive rear wheel only without diff lock any ideas ?

western Posted January 27, 2008 Share Posted January 27, 2008 Nope, the wheel with the least ground contact/resistance will spin, the power will try to find the easy way out without having to do any work, the drive is shared to both axles with or without the difflock engaged, when it is engaged it just locks the front & rear axles together.

BogMonster Posted January 28, 2008 Share Posted January 28, 2008 Front LH wheel normally spins first if not in difflock. Could be the weight on the drivers side on my vehicle though Quote Link to comment Share on other sites More sharing options...

Without centre difflock engaged, your vehicle is four wheel drive, BUT, if only one wheel looses traction, it will spin and the other 3 wheels will not be driven. When you engage centre difflock, a wheel at the front AND a wheel at the back need to loose all traction before drive to the other two wheels will be lost. The centre differential is only designed to cope with minor speed differences between front and rear axles which occur in normal driving on road. As soon as you venture offroad where there is the slightest possibility of wheel spin or slip, you should engage the centre difflock. The centre diff is not strong enough to cope with high differential speeds which occur when it is not locked and a wheel spins. Similarly, the diff is not designed to cope with the shock loads which occur when a spinning wheel regains traction. Once locked, the diff will take just about any abuse you are likely to put it through. Regards, Diff Quote Link to comment Share on other sites More sharing options...
nige90 Posted January 28, 2008 Share Posted January 28, 2008 All coil sprung Landies are permanent four wheel drive. Your front wheels let go first probably due to weight transfer on hard take off. Quote Link to comment Share on other sites More sharing options...
Roverdrive Posted January 29, 2008 Share Posted January 29, 2008 That is the advantage of the BW transfer box, as the viscous coupling arrangement prevents wheel spin when pulling out of junctions, or on hill starts with heavy loads. Ahem.. Also stops you forgetting to re engage diff lock when you have nipped out for a pastie at lunchtime when competing in a trial event.
