Thread: Centre diff lock stuck on

Ok tried rear wheel up. Won't do a full rotation (handbrake off). I have the front and back drivers side wheels up now. They spin same direction in unison. Can do full rotations. Centre diff light still on.

Regarding surgery - off with drive shaft, any wires, linkages and bolts. Pulls off with out too much trouble - just a pain. Oh, draining oil might be an idea. Just remember how it all assembles as you pull it apart. Watch for detente bearings incase they roll out - from my experience they should be reinserted from inside the casing before re-insertion of shaft - grub scrw and spring from the outside of the casing. The on/off ring and its fork should be obvious. Inspecting internals of the diff itself require splitting the two halves, and mark the two halves before you pull them as the bolt holes are not uniformly spaced from memory - you'll need torque wrench etc for reassembly.

Hi no unexpected noise but have had trouble disengaging in the past but usually after 20 mins of reversing and swerving it comes good

And you didn't suspect something at this point?

Or did you do the "I'll drive it till it really breaks" trick? I'm known for doing this...

Thanks for all the help but finally came good. 2 wheels in the air. Spinning the back while my mate changed the gear on and out of diff lock and finally it unlocked!

Sorry trundle what do you mean. How can I drive it until it breaks when it disengaged previously. As I said no unexpected noise. Thanks for the positive advice

Just mean that if you've had an issue with it sticking and needing to reverse and swerve around for 20min to get it out several times before then there was an obvious issue, but you seem happy enough to re-engage the diff and continue to use it.
Nothing smart arse intended, as I am happy to drive some with a known problem sometimes, for any multitude of reasons, mearly a question, of are you going to look for the cause, or continue to drive it knowing it will likely happen again?
Be interested in knowing what was causing the sticking if you go down that path.
Cheers

Good to hear you got it unlocked. Before your Iast post was going to suggest one more thing, and it may be worth trying pull (unscrew) the sensor out first in case it is hindering the change mechanism. I'm used to being under Disco so you may have a bit more room for reaching it in a Def. Reach up over the rear of the box and you will feel it by following its wire down, then figure out which ring spanner or open end will fit and unscrew.

Best if you take it apart and find the prob
