After a bit of spirited driving today I seem to have developed some clutch judder, especially noticable when setting off in 1st.
What have I done!!!!!!!!!!!!!!!!!!!!!

Maybe you just overheated it and it'll be ok tomorrow. Here's hoping as it looks like a sod of a job.

I'm starting to wonder how long my clutch has left, it judders like a good'un when it gets hot. It recovers once out of traffic and this has been going on since last November !

Mine was like that. I did at least 30k on it. As soon as it aproached an area with 1920s road infrastructure and the resultant congestion, it juddered like mad then cooled down and was OK once moving again.

I'm going to change mine this summer I think. My car is 20 years old, the last owner had it for 12 years and didn't have the clutch changed in something like 50k miles and it's now done 92k so my guess is that it's the original clutch. Still feels great but as my main seal is leaking oil in for a penny...

Just need a transmission jack to lower out the transaxle.

I think some clutches are like that. Our mondeo started doing it after I (I can barely bring myself to say it) beat a mini cooper s in a mini (sic) traffic lights grand prix this afternoon... well it amused my 2 year old daughter ("green! go daddy!") and I although my wife less so and that clutch has about 1000 miles on it.

I'll go out & try it later, I had also been stuck in traffic for a while so we'll see how it is today.

Thanks for the replys :-)

My S2 used to get rather juddery after heavy use in traffic, and I know sevreal 968 owners who have the same problem (not noticed on mine but then I've not been stuck in heavy traffic since I bought it). When the S2 clutch finally gave up the ghost at 105000 miles it was the rubber hub that failed - a common problem apparently.

hope that helps

Wouldn’t worry about it too much. Common problem, my S2 when I had it, 38k on the clock (5 years old) used to do it, when hot. After crawling in traffic lots of clutch up/down movements, you just couldn’t pull away smoooooothly, without juddering no matter what you tried.
I used to hate getting stuck in traffic jams with it, for this reason. 2 x friends with S2 Cab’s both had the same. I think it just all gets a bit hot back there…

My old 944 used to do this also when hot, then fine again later. I haven't experienced it with the 968. Can anyone who knows about these things explain what is happening and why the 944 is particularly prone to it ?
Thanks.

Hi Bananaman
Been interested in a lot of your postings as I have recently purchased an S2 and have wished to ask similar questions. Well guess what, my clutch also judders when hot as others also describe. This week discovered a mag called 911 & Porsche World, April 2004 addition with article on buying an S2, notes 'clutch judder can indicate that the friction plate's shock absorbing rubber centre has broken up' what ever that means! Can anyone advise how expensive this is and if it is the most likely cause. From other's comments it seems that you can continue to use the thing in this condition for some time.

I don't think that the judder is the rubber centre breaking up, as mine did it for 60,000 miles before the rubber centre failed. When it did break there was a lot of take up in the transmission, causing progressively severe lurching on gear changes and ending with an £800 bill for a new clutch.

My S2, still on original clutch, has done it for the 35,000 miles I have had it. It's going in for the clutch next monday. I will try to post pics of the rubber center.

I was worried that I was needing a new clutch & had a look on the hartech site £520+VAT
www.hartech.u-net.com/Docs/service_prices12Aug02.pdf
My car has done 98000 miles so I recon that sooner or later I'll need a clutch, any ideas on life expectancy for this item?

I thought it was only the 944 Lux that had the rubber center, all the others has real clutches as I have replaced the clutch on my lux with one from a turbo and with no rubber center on it

Same with my old S. It juddered like mad when hot in traffic but was fine when cool again.

Ah 'they all do that' then do they? Had it happen a few times when slipping the clutch in stop start traffic.

Can you tell me if changing the clutch actually cured the problem? On my 1989 944 Lux the clutch just failed at about 102000, I never actually suffered any juddering. On my current 1991 S2 (I'm second owner and have had it 12 months / 14000 miles), the clutch has always juddered when the car is hot. It's the original clutch, 153000 miles, and it works fine, except when I'm in traffic jams and it heats up and judders. I do find that there's less judder when I pull away in 2nd gear. As soon as it has had a run and cooled down it works fine again - until the next traffic jam. My mechanic seems to think that this is a 944 trait and that changing the clutch won't cure the problem. And what's this about changing to a non-rubber clutch? Any ideas please? Thank you.
