Total loss of drive....bugger!

Yes the hole for the pin to pass through was ovoid, and the mechanic did say the diff was probably a gradual failure over time.

My CDL engages relatively easily, that's not just the light coming on, I check it every time before I go 4wd, just by jacking up a front wheel and operating the CDL.

The past week has been a bit hectic, but sitting back now with a bit of time on my hands having breakfast on a Saturday morning, I think it was just an unfortunate set of occurrences that all seemed to happen at once.

The diff had probably been on it's way out for awhile, and just decided enough was enough on the dealers driveway. As for my initial failure, total loss of drive, well it would've been great to see the old clutch. After speaking to the mechanic and the service assistant, I think the service assistant neglected to tell those that mattered that I required the old clutch. It wasn't a matter of covering something up, I guess it's so easy to blame the apprentice, the service assistant just forgot to tell anyone, even though I did ask on two separate occasions

Just like he forgot to call me before they started stripping the front axle. When I was arguing the point in regards to paying the $560 to reassemble, I got to speak to the manager of the service department, he asked the assistant if I was called at the initial stage where they suspected diff issues. The answer was no, to which he replied "then we can't expect the customer to pay".

And I agree with Jon's comments,

The problem was diagnosed as the clutch, which was replaced. After this the vehicle was driveable, as is clearly evidenced by the vehicle being driven onto the truck. Sort of suggests they fixed something.

As an owner of a work shop all my mechanics from the apprentice up know that parts never leave the premises or get chucked out until they customer has sited and been fully explained what has gone on.
On the case of no drive i have a fairly high tune in my 110 which we do in house and have spun the centre out of two clutches,one at 28000 and one at 42000 no sign of slippage at all the clutch facings were like new both time no drive but terrible noise

Thanks grinna, my car has a BAS tune with EGR delete, the mechanic did say that there was very little friction surface left on the clutch and it had hot spots all over it.

Our tune gives more torque than most
If the clutch facings were worn to the rivers it still wouldn't have lost drive totally you would have felt it flare up and then still try to drive you just wouldn't have nothing at all

Out of curiosity what sort of torque and hp numbers does your tune provide??

Sorry for derail of threat ozy013.....just curious

Sent from my SM-G925I using AULRO mobile app

The last thing i want to do is be responsible for derailing a thread which seems to happen all to often on this site which is one of the down falls of this site
There is a lot of information here and also a lot of b/s
I know that our tune has more torque than most but not as much hp,if you know diesels its all about torque.not saying ours is any better or is faster but will drive differently in different circumstances if you would like to start another thread on performance that's fine but i would prefer to talk on the phone.cheers

That's what I thought, I've had clutch's, two actually, let go in trucks over the years. One was like how you describe above, and the other was coming to a stop at a set of lights in Bendigo fully loaded, the clutch wouldn't disengage and she just kept trying to chuck along. First thoughts was master cylinder but when they stripped it the clutch was completely stuffed.

My clutch has operated the same since I bought the vehicle 2nd hand, 4 years ago, I don't ride the clutch, always start off in 1st even though it is a bit low. It's just hard to believe it would cause total loss of drive, that quickly.

Hi Ian,
Totally agree with what you have said. I would have expected a call as well if ongoing repairs were outside the original discussion of the work needed, especially given the major costs involved.


Given you are a professional driver of a Kenworth with a crash box, in no way did I think that in your case, you did not have the CDL engaged properly. Just that I was speculating "if" this happened then "that" would have to happen as well. I know my Defender has its little surprises just waiting to be discovered. As per my original reply, I approached a steep rutted hill with what I thought was low range selected and CDL engaged. Got to he to of the hill and neither was the case! That actually impressed me as everyone else was having trouble in low range.


I hope you get it all sorted soon. I like you, would go stir crazy if my Defender was off the road for too long!

Different model Landrover, but I have had a clutch fail by the centre breaking out of the plate - just gave 'no drive' as described.

Not sure whether I mentioned it earlier or not, but you don't realise how much time you spend tinkering, fixing and doing preventative maintenance over the weekends, until the Defenders not there.

I've now read all the books I got for Christmas, and today has been spent building a rebel base out of lego odds and ends, for my sons xwing that he got for his birthday. Quite therapeutic actually....:BigThumb:
