    Very informative, will be useful... One Day

    Very informative write up you've got there. Im in a bit more of a predicament. and hoping you gents can help pointing me in the right direction for a spare part.

    The story is. I've had my Landy for 6 months, and at the time was told there was a problem with the front right freewheeling hub.This weekend I found some time to open them both up and investigate. It turns out the collar on the base plate is sheared of in the corresponding locations to the locking pins. My guess is that a hard nudge on the hub ie rock/ tree whilst off road did its number.

    What it looks like...

    What it should look like...

    Thankfully the hub stays on whilst in the fully engaged / disengaged position, so everyday driving is no problem, however its something I need to fix soon. Any ideas where i could go looking for parts... ideally located in Australia.

    Thoughts and help welcome, and thanked in advance.

    Not sure if you'll find spare parts so you'll have to look for another Selectro hub.
    Maybe someone has one that's damaged but the part you need is OK. Worth advertising under Wanted in the Markets section of the forum.

    Excellent writeup and rebuild - thanks Colin.

    FWHs weren't the best idea on Series vehicles and I suppose most owners ended up removing them (I did - still have them "in stock").

    They seem to have found a new lease of life from owners of 6X6 Perenties who fit them to the rearmost axle in the hope of reducing tyre scrubbing

    The advantages of free wheel hubs on Series Landrovers are minimal, and the disadvantages very real. They were mostly fitted by dealers eager to sell "optional extras", and contrary to your supposition few owners actually removed them, I suppose because they were not about to admit (even to themselves) they had wasted money.

    I have difficulty seeing how the free wheel hubs on the rear axle of a 6x6 could have any effect on tyre scrubbing - the reason the tyres scrub is that they are being dragged sideways on corners, not because they are turning the diff and prop shaft. But I suppose the same factors are at play!

    ... got it in one JD

    maybe I should have termed it "unnecessary tyre wear & driveline stress"

    Quite often replacing the O-ring doesn't do a thing because there is a groove worn in the part you rotate, where the O-ring sits against. Selectro and Dualmatic parts are inter changeable.

    I've removed FW hubs from most of mine, I reconditioned the Selectros in this thread but haven't re-fitted them.
    The biggest downfall of using them is the lack of lubrication to the Railco bush unless you regularly engage them (that reminds me I must engage those on my SIII shorty next time I use it.....)
    They might be handy if you snapped a front driveshaft, just drop the propshaft and disengage the FW hubs to drive home.
    I was considering getting a couple of worn drive members and machining out the splines, these could then be fitted to front or rear axle as a 'get home' bodge should a driveshaft break.

    A little considered potential issue with free wheel hubs - you are driving with the hubs unlocked, climbing a hill and you break a half axle (not an unknown occurrence!). You stop it from rolling back by applying the brake. If you are alone, now what do you do? As soon as you take your foot off the brake, it rolls back. The handbrake does not work. Unless you have a passenger who can hop out and engage the hubs, or you can allow it to run back slowly into something that will stop it, you are in a serious pickle!

    I should point out that to lubricate the top swivel bearing, you do not need to engage the hubs. Engaging four wheel drive (while stopped) will have the same effect (unless one side is a lot easier to turn than the other, a rather unlikely situation. This saves getting out and getting your hands dirty.
