    Perentie front diff failure - help!

    So on my way back from fire tower duty today, I was accelerating out of a roundabout and suddenly and abruptly lost drive.

    The sensation was of a failing clutch.
    No loud crunching or rattling sounds.

    It failed quite luckily right out front of my favorite mechanic who quickly diagnosed front diff failure.

    in on-road setting with center diff unlocked, front shaft spins, rear does not.

    Drove it home with center diff locked (approx 3km) glad it failed then and not in the remote area I work.

    With center diff lock engaged both shafts spin as you would expect.

    Have not yet had timd to drain the diff and pull the cover off to inspect.

    I'm seeking advice as to likely causes and what I'm looking for with cover off.

    I replaced front U joints a while back after the one closest the dif ran dry and failed.

    Mechanic seems to think i should be driving the rear not the front and says "something is ass about".

    I'm leaning to the thinking that the british just design things ass about...

    Any advice would be greatfully received...

    Im guessing you have broken a front axle
    Now the cdl is a diff and if you have even drive front and back when it is unlocked that is what you have until you loose traction or break something .
    In this case all power goes to the axle that has the least traction either on or off road conditions or you have broken something then when you engage cdl both front and rear axles will be driven

    It could be a stripped drive flange. They are a lot cheaper. A sacrificial part.

    As rar110 said, Pull the dust caps off the front drive flanges and engage first gear, diff unlocked and see if the shaft is spinning in the flange, we have done 4 on our 6x6 so far..

    No inspection cover on front diff, only rear.

    You have to strip all of the above items before the diff will come out anyway, start on the flanges and work your way in.

    If i were a betting man i'd put my money on Blknight's suggestion

    Driveline is behaving exactly as it should be with such a failure, trusty mechanic just having a bad day I suspect.

    Your mechanic was having a bad day, thinking it was ass about. The open centre diff means drive will go to the axle offering the least resistance ie the axle with something broken and spinning freely.

    Thanks for the replies guys - I had been locked out of my account due to some password reset issues.

    what I have done so far:


    pulled the filler plug from the font diff and stuffed an inspection camera in there.

    looks shiny and clean, go bits of gears.

    with CDL disengaged and 4 wheels on the ground, I can freely turn the drive shaft.

    I feel resistance every 180 degrees of turn.

    I can see the crown gear and spider gears turning.
    oil looks good colour.


    with passengers side wheel jacked up, and rotating, the crown gear moves.
    with drivers side up and rotating, crown gear does not move.

    A slight wriggle can be seen every 180 degrees.

    So thinking axle issues.

    I also put it in gear, and observed the splines on the passengers side drive flange, they don't appear to be turning independently of the wheel, so I think I can rule out stripped drive flange.

    Next question - where do I find a replacement?
    and how can I determine what side of the CV it is?

    I found something on ebay, but lost the link.

    More likely to be half shaft than CV as indicated by Dave.

    Inspection camera, good idea.

    Probably inboard of the CV, outboard shaft is usually part of the CV.

    Can your camera see up the axle tube from the diff housing? spin the wheel and you may be able to see where the breakage is.
