    While coasting alone fwy at about 100km I developed a problem. My speedo hand started to bounce. Anywhere between 0 - 200km. Where do I need to look to fix this.

    Sounds like the speedo transducer on the transfer box, the normally square drive wears and ends up round. AMR1253 (YBE100540) Speed and the O-ring seal is 571665. Easy to change.
    Cheers

    As a short term solution just use your GPS, if you have one it gives a true speed better than an anolog speedo

    Just behind the handbrake drum as shown in the pic attached. Its held in with a single bolt. They are not cheap and Karcraft have them listed at $146.15 part No. YBE100540. Or if you can wait get one from the UK for around $60 shipped (UK EBAY).

    My speedo did this before it "died".

    All it was was a dodgy/loose connection on the electrical spade bit at the transfer case. Fixed.

    The same can happen with the tacho, a loose/dodgy spade bit on the alternator. Give it a little twist with pliers or something to make the connection a lot firmer.

    excuse me being a dumb ass...

    how do I get to that photo.. I'm happy to pull things apart but I can't find anything that looks like the electrical spade on the transfer case...

    I did have that problem with the tacho, easy fix...

    Ahh, found. Speed transducer had some mud in it. Ordered one off paddocks. Hopefully that solves it. Btw how often should you change oil in you transfer case?
