Not sure if its a problem, maybe just my curiosity but - ........

I know what the Diff Lock is for - it ensures that all wheels will be driven even when there is no friction. It stops wheels spinning by locking out the differential on both front and rear axles.

BUT, what I don't know is how does shifting the diff lock lever to the left make this happen? I could maybe see how it could physically do something to the front diff., but how (physically) does it make the rear axle differential lock?

Car is a late '94 M reg Tdi300 Disco 138 k miles used for towing because the tow hitch has had work done to the trailer socket wiring. Reverse gear is to the right and towards rear.

I am asking because I think that sometimes my diffs are stuck in locked position as the wheels tend to 'jump' or 'jerk' around bends on the road (at say 20 - 25 mph - diff lock light NOT on and yes the bulb does work when I consciously put it into diff lock). Also, sometimes when I try to come out of diff lock, the dashboard diff lock light stays on. It can sometimes stay on for 5 minutes and then goes off, typically at the same time as I change a gear (any gear!).

So could somebody try to explain what's going on here?

thanks if you can.

nope the diff lock on standard landrovers works on the tranfer box, it locks the centre diff so both prop shafts turn at the same speed if one wheel on both axles has no traction it will just spin aimlessly andyouwill loose drive

see above

sounds like your cv joints could be buggered

Thanks for the quick response G man! I understand completely about the diff lock now. Yikes, I hope me cv's will last acouple more months 'cos I guess they would cost a bit to get replaced!
 
no probs mate, it might not be cv's, check all the bushes etc, if it was diff lock stuck in the gearbox would be buggered by now, as it would hae 'wound' itsself up and gone bang
 
CV joints aint too bad to replace - about 30 quid each and half an hour each side.
