Hi all,

I've just been on to my local Nissan garage for a quote for a new clutch as mine has done nearly 70k miles. I've noticed that when I accelerate hard I get a little bit of clutch slipping, so think its time to replace it. Also, it does the grating noise on quick changes, which I've read about as a sign it is on the way out.
They said that they need to replace the clutch with a dual-mass clutch as I'd be using it for towing - £531.29+VAT, but with labor comes to £1022.31. If the Flywheel needs replacing I'd be looking at £799.81+VAT, but they wouldn't charge for the labor on this. So, by my estimates that comes out as £1982 for a clutch change?!? Is this pretty standard? I am pretty technically minded, and may have a go at doing it myself - assuming you don't need any special tools? I've a copy of the Electronic Workshop Manual, so I know that it involves dropping the gearbox and transfer boxes. Is it something I can do myself (without a ramp), or is it something best left to a specialist? I'm wondering if it might be worth giving a few specialists a call.

Cheers,

Yes, I put dual mass clutch for a reason - that's what the girl at the garage said. Surely a dual-mass flywheel would have been more appropriate...

I had a new clutch and solid flywheel (cos I tow a 3tonne trailer) fitted to my truck in October 2011. £334.75 for Clutch kit, £26 for crankshaft sensor. Charged me £300 labour but that also included changing the leaf springs.

Obviously not done by a dealer, but a local mechanic I trust and who knows his 4x4's.

If you are going to do it yourself, be wary of damaging the crankshaft position sensor.

Do a bit of searching on the forum regarding the Dual mass flywheel, there are pros and cons of fitting a Single mass flywheel as a replacement.

Have a read of this... It should help you decide.


Daily telegraph & honest John (online mechanic) review on DMF

It's very common, unfortunately. Dual mass flywheels (DMFs) have been an unmitigated disaster. The reason for them is to absorb some of the engine torque, putting less strain on the transmission, particularly on the upchange from first to second. But their failure rate has been so high that companies like Ford and Mazda are now abandoning them in favour of ECU software that damps the throttle on upchanges, achieving much the same effect without the huge cost of having to replace DMFs every 60,000 miles.
------------------------------
My clutch has just started to judder (5yr old only 29000miles) so been doing my homework, as an ex fitter an garage owner I was going to do it myself, but time and the warranty factor don't make it viable for me to do it.
If you buy the parts and fit them, you have warranty on parts only, if a garage does it you'll get parts and labour warranty...
Inc vat, £400 parts and £300 ish labour seems to be the going rate for the dual mass flywheel conversation kit to a solid clutch, that's a new flywheel/clutch plate/clutch cover and release bearing. Although the initial purchase of the conversation is more expensive than replacing a DMF with a DMF- in the long run you'll find it cheaper. Do be aware though, the DMF is there to reduce vibration and torque stress through gear changes...easy acceleration from standstill is always a good way of saving your driveline !

My navs booked in 21/5/12 for the converstion, quoted £700 all in with (whilst im the owner/non transferable) lifetime warranty.
I'll post back on here when it's done.


Hope that helps.

Forgot to add...
Nissan advised £450 to remove box and investigate an a total of £2000 to replace it,
As you can imagine it didn't take me long to say NO !

Managed to get it booked in at a local Clutch specialist -they specialise in 4x4s so knew exactly what I was on about. £595 including labour and VAT, and they are fitting the Exedy Clutch and a dual-mass flywheel, both with a 2 year warranty. Took it over this morning, so if all is good, I will let you know how they get on...

well, I've just had a call from the garage. Apparently there is a brass collar around the input shaft into the gearbox? Well, mine is in several pieces! A £4.50 part, that normally doesn't fail. I wonder if that is what was causing that grinding sound?!? :-s

Hopefully be ready for collection tomorrow (fingers crossed).

Well, Car is back and clutch feels light as a feather! Biting point is right low, and no feel of crunching or slipping through the gears!
Place I went was Cannock Clutch Centre on the A5 in Cannock. If you are in the Midlands, I strongly recommend the place. It's owned by a chap called Tony and he really knows his stuff. Got to take it back in 500 miles and he'll put a spanner on everything and check all is okay. Wouldn't get that level of service from the main Dealer! £600 for dual mass flywheel and an Exedy clutch, both backed with warranties (12 for flywheel, 18 for clutch).
