Diff Lock

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.

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

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?
see above
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!).
sounds like your cv joints could be buggered
So could somebody try to explain what's going on here?

thanks if you can.
