Judder

Post by **Pyoor_Kate** » Fri Oct 01, 2004 5:17 pm

Hey folks,

I've got that judder back, in fact I've had it for a little while: Having replaced the engine steady bar / mount the judder went away, maybe for a day or two. Came back. Tweaked engine steady, went away, came back, took a few days to get around to it, tweaked it, went away for a few days, came back.

So, I'm thinking I can't *keep* tweaking the engine steady bar, and it's *probably* not that that's the cause of the problem.

It is only in first / reverse gear; I had a new clutch 15k miles ago, so presumably not a clutch problem (we hope)... The gearbox steady wire looks, well, slightly slack but not incredibly so (and was a little unsure of how to adjust it, then it started raining on me so I decided I didn't want to adjust it).

Has anyone got any suggestions for what it might be?

Could it be the old, very sorry looking engine mount rubbers?

Incidentally, it came on at the same time that one of the rear springs broke (i.e. there was no shudder, spring broke, car obviously shuddered horribly, replaced spring, reduced shudder, but shudder none the less remains.....).

what does 15k mean 15000 or 1500
if its 15000 then your clutch will probably be worn out again.
r u sure that the full clutch was replaced and not just the clutch plate

15,000.

The clutches only do 15,000 miles in a mog? Meep.

1 x Clutch Kit was fitted roughly 15,000 miles ago....

yes 15k is 15,000 (good old metric units - everything in thousands)
Cutch judder can be a pain and rarely goes away once it has started.
First thing to do though would be to replace the tired engine and gearbox rubbers - Unfortunately the new ones are reported to be 'quite hard'.
It might cure the judder but you may get some new vibrations instead

[Clutch life all depends on your driving style, so 15k could be either barely run in or nearly worn out. Some people hold their car on hills using the clutch everyday hence needing a new clutch every year but others can nurse a clutch for a couple of 100k's by never doing boy racer starts and not holding the car on the clutch.]
Clutch judder due to the clutch itself normally means a defect somewhere on the clutch, flywheel, pressure plate or a wobbly input shaft (eg damaged support bearing) - it is more likely to show up in the early years.
Clutch judder due to contamination is also possible - oil on the disk gives it a stick-slip behaviour which can be a real pain if you wanted a smooth take up.

IIRC there is the possibility of "glaze" building up on the flywheel. This can cause judder and vibration, and can be reduced by sanding the surface lightly, although I'm not sure it's recommended...

If you fitted Grumpy's top steady, make sure that the mounting bolts are still tight...

they can work loose over time.

15k? Madness... Our Metro's done 40k and hasn't needed a clutch yet - AND it went through two learners! ;) If the clutch is badly worn at 15k, there must be something amiss, surely - like riding the clutch, or it being badly out of adjustment??

I agree with Gareth - none of my cars have needed a replacement cluthc plate. The best was a Fiesta 1.4 which topped 108,000 miles on the original.

As you erite, gentle use, no boy racer starts & it will last a long time..

Tighten the gearbox steady wire just enough to give slight tension this often helps to stop judder.

I should hope not. the comparable German car I had did 97K before one of the clutch plate fingers broke. Even then the friction plate was excellent and I certainly used to give that car some hard driving. Incidentally it broke on our holiday down to Cornwall. I drove from Salisbury to Penzance, trying not to change gear, screaming round roundabouts at 40+ mph. Where I did have to change I tried to match the revs to the speed and mostly got it right. Damn good fun though

15k for a clutch

, my wife's mk2 golf td has just hit 340,000 with lots of towing and has only had one clutch in it (been in family from new)

Agreed that 15,000 is low mileage for a Moggie clutch if all 3 parts were renewed but as Ray states driving style has a lot to do with it and you cant compare modern cars with self adjusting cable type clutches to the Moggies direct action manually adjustable one.
Adjust the gearbox steady as Les suggests, and have you overdone the engine steady bar as it should allow some slight engine movement.

Funnily enough, having posted this the judder seems to have got markedly less. Indeed, I didn't notice it at all on the way home from my parents which is odd.

I'll have to see if it comes back, but I'm hoping that whatever it is might have resolved itself

It probable felt threatened by your posting, it knew the game was up.

What?! You mean Kate's car can read and use a computer?!?

Yes, why can't Phyllis???

Hah, it came back today, after a noticable 'TWANK' noise (while travelling forwards, in 3rd at about 25 mph). I've yet to locate either the source of the 'twank' noise or, for the time being, the judder. But rest assured that come next Sunday, if it's remotely dry, I shall be found relaxing under Rebecca.

Not only can Rebecca read and use a computer, but she can telepathically communicate with Hebe. They seem to hatch plans together... It's most distressing

Crikey! And I thought Phyllis was clever by choosing to break down close to home (seriously - never breaks down further than 10 miles from home

)... Maybe I should sit her down with a bit of Mozart and Milton so's she can be educated?

Kate, if the twank is sorta metallic, could it be the propshaft bearings?

*hopefully* not, she had a new one of them not long ago.

But did you have both uj`s changed or just one.
I may be going mad but does not one of your postings say Rebbeca is under warantee with CW ? and you were having some work done by them.
