Hi mate sorry to hear of your problems, so you saying that you have no drive at all no mater which gear you are in? so with engine running no foot on clutch can you select gears? if so your clutch has failed, no big deal, Rick

Hi and welcome aboard. I do know that you are not supposed to use 4wd on hard surfaces, wheels need to be able to spin slightly to release tension. To be honest it sounds like clutch has failed but others will be along to give a bit more advice I'm sure. Happened twice on my truck the friction plate of the clutch basically rips apart hence the noise.

No drive at all yes can select gears release clutch an nothing, no big deal clutch failure lol last clutch failed on me was on a td5 cost me £600 this is the 2nd terrano in a matter of months done this I wont chuck money at them get rid an get another I cant afford to chuck £500 - £600 quid at it to find out its not clutch but gearbox. but thanks for the advice waht was the banging noise then i thought the transfer box had gone bang????

Could have taken the transfer box out but that would have only affected front wheels, if it was the transfer box, even when you were in 4WD you should have been getting drive at the rear wheels still.

The fact that you get no drive now at all means it's got to be the clutch, I've just done mine, I'd say click the project thread link in my signiture but as you're not a paid up member you wont be able to see the thread, I've done a well documented write up on the job and did it on my own, on the drive for under £200, depends how handy you are with the spanners.

If you do want to get rid of it let me know

Hi and welcome to the forum.
I think you have been given the correct diagnosis, but it might be worth checking if the 2-4 wheel drive select gear lever hasn't been thrown into neutral.

If you select 2 wheel drive high, do you still have no drive ? EDIT just read your original post, looks like you tried that.

Couldn't you nip it down to Scripp's garage in Aidensfield lol.

There have been a few reports of clutch failure, clutch material breaking away from the plate, is there a common factor?


Are they all original clutches fitted to the tdi version, if so between what years?

Having the earlier non intercooler, with original clutch, I would be aware of failure for this model, so either the clutch material is different, or Renault have done another cost saving exercise.

Or it could be a poor batch of friction material.
Clearly the tdi has more power than the td, this might have an effect, just seems odd.

I am wondering if as a result of descending the hill with 4 WD engaged in low you have started to get some diff wind up as you should not use Low drive on essentially hard surfaces as has already been mentioned.

As a result something had to give so the weakest point was the clutch rather than the transfer box or diff. Just my thoughts on the subject.

I don't think transmission wind up can really directly affect the clutch.

Basically, on an unmodified T2, there is a Diff in the front, so no cross axle wind up there, and at the rear, is the LSD, so that will break away to to stop Rear cross axle wind up becoming a problem. So on a T2, the only wind up that can happen is front to rear, via the prop shafts and transfer box, but there is no wind up between the transfer box and the gearbox, or engine, as that is just the normal direction of drive.

The only thing is, may be the snatching caused by the "wind up" suddenly unwinding as the wheel is forced to slip, and then re-gripping might have cause it to go, but I would have thought it was already well on it's way for that to happen.

I have never taken one apart, but when Ryan did his "Photo Expose" on the transfer box, I thought there was a large chain that took the drive from the rear to the front. I would think that would be the weakest link, but even then, if that broke, you would still have drive to the rear wheels.

A well reasoned point but are we saying you can get diff wind up if the clutch pedal is depressed ? If so you are right. I am just thinking that the cause of the turning momentum into the transfer box comes from the engine so can't that be a counter force from the transfer box as an opposing force ?

Just as an asside on a different type of 4 x 4 set up.........

On my old Merc 300TE 4-matic there was a limited slip rear differential that had some sort of electronic lock and the front wheels were driven from the front transfer / gearbox unit through very spindly front drive shafts with a hydraulic link of some sort that engaged the front wheel drive when needed, it was also an automatic.

Most of the time it was in rear wheel drive only and the front wheel drive only kicked in at lowish road speeds (below 50mph I think) when the wheel sensors detected slipping. Mine had a fault in that the front wheel reluctor rings that were built into the front drive shafts were badly corroded so at higher road speeds a fault would come up on the dash (SCS ?) in the form of a yellow triangle. If you reversed the vehicle with a fair amount of steering lock this would cause the rear diff to lock causing some horrible rear axle hopping noises as the front and rear seemed to be in competition. As the drive shafts were £1500 each and the motor was only £1000 I lived with it for 3 years. I soon found out that if you cadence braked as you reversed this would disengage the electronic diff lock and stop the rear axle hopping. Luckily none of these faults would come up on a normal MoT test so it always passed.

Yes you can if for instance you are in 4 wheel and decending a hill but main gearbox in neutral and make a turn then wind up will take place, I am not for one minute saying you should decend a hill in neutral just trying to explain, Rick

Okay now my brain really does hurt I guess it's an internal battle between the front & rear drive trains if it can occur in neutral !

[elty001]

Yep,in neutral you are only stopping the power to the wheels not disengaging 4wd.

thank you for your reply gone are the days were i roll about underneath cars 25 yr ago I would have had it stripped an repaired to auld for that now i'm afraid ebay it will go for spares or repair cos I'm not chucking loads money at it will just go buy another its easier lol

[Deusiri]

transmission wind up you cant drive in 4x4 mode on hard ground excuse my ignorance why not??? if the hard ground (Road) is icy or snowy i thought that was what the 4x4 feature was for????? this being the reason I got a 4x4 as winter here is icy snowy an bleak its a 1st I have heard you cant drive on roads in 4x4 mode whats point owning one then if they only good for off road an mud??? I might aswell just go buy a freelander permanent 4x4 if this is the case with terranos but then freelanders dont have the towing capability
