    ok, so have freelander 1 with L series motor. Prop was missing when bought. I have a replacement with decent bearings and a moving VCU. So, without attaching it all, is there a way of checking if IRD is okay? Flange turns a bit both ways with a gear mesh clang. No sideways movements.

    Drain the oil, but only after you have loosened the filler/level plug, inspect the oil, the pinion can also be removed for inspection which gives you access to light up and view bevel gear in ird.

    Yes the fill plug is on the rear facing side - its the soft one made of cheese!

    When you drain the oil you won't be looking for bits of gear teeth - if you happen to find some then you're diagnosis is very simple - enjoy 2WD motoring! You're looking mainly at the colour of the oil. If it still looks like oil, then signs are good to reinstate 4WD. If it comes out greyish - then that's the bearings ground to a pulp and suspended in the oil. Once again, enjoy 2WD motoring. Even on a good IRD its common to find quite a bit of swarf (sludge) on the magnet at the end of the drain plug - don't be overly worried by this if you find any.

    If the oil comes out looking like oil - then things are looking up. However, its possible whoever too the props off changed the oil then - they would have been foolish not to if there were problems. So then you can unbolt the rear pinion, remove it and inspect the crown & pinion gears for signs of damage.

    Don't forget, you'll need 4 indentical tyres (make and model) that are pumped to the same pressure, and once you have the props installed do a 1 wheel up test to ensure the VCU is within acceptable 'tollerance' for use.

    Good luck.

    to remove the IRD fill plug use a 6 sided socket - 19mm - it won't check the fill plug.

    thats all for the info. This check will be added onto the list. Just found the rear subframe is crusty, somebody must have parked it in the sea i guess...

    Unfortunately they all get crusty, especially the fuel tank cradle. :(
    Having said that they are much better than most other cars of the same age. :)
