Clutch Juddering

[IS 200]

Guys this car has an absolutely amazing look and drives beautifully. Well, apart from the occasional judder from 1st. Has anyone managed to find a solution to this judder problem yet?

[ChrisIS200SportTTE]

Dual Mass Flywheel judder so I'm told. It's completely normal unless the judder is severe :)

[Steve]

yeah pretty normal for an IS.. Flywheel judder

[CHUNKY CHIP]

mine does it on cold days and after a few miles depends on temp its fine other times it randomly gets upset if i ride it at the lights but it doesnt hurt on the odd occasion

[Dewfallsuk]

Mine is random goes weeks with no judder then next morning it's a pig. Takes the shine off the car, does not seem to be any cure?

Yeah mine does in once every so often. If it starts juddering I just put the clutch back in and then let it out again. Seems to cure it for me

Have anyone had luck with welding the flywheel together?

[jomo]

Try to keep the revs around 1500 rpm when pulling away, the dual mass flywheel is the culprit, read someone welded the two parts together when they had a new clutch fitted which fixed the problem.

Or buy a new one from lexus!!! I dare you to ring and get a price lol...

Sounds a bit drastic?

Nah. I think this would be the best way to fix it :) You are just gonna weld the 2 moving parts of the flywheel together, and make it a solid mass flywheel :) In theory it should work.

I work at Toyota/Lexus here in Denmark and i got the judder problem. I asked for a price on a new flywheel. The price was £830 and that is the price i get it at, working at Lexus. So if a costumer walked in it would be £1300. :S

There is an art to pulling off in these cars.

I find the opposite

I let the clutch up with Hardly any rev, the car takes up the drive with little forward movement, then drive off! Presume that is the duel mass cushioning the drive?

My judder is mainly on hill starts but as I said random, tomorrow she will be fine?

At that price I'll live with it.

[ChrisIS200SportTTE]

DMF part only £900. nearly £2k fitted at dealer!

Solid mass flywheel part only is less than half that price. I've been told a solid flywheel would work fine by my local mechanic.

Lexus told me I'd need a new flywheel within 2000 odd miles as my clutch pedal squeaks quite a bit. That was 8000 miles ago and it's not deteriorated and some WD40 every now and then and no squeak! :)

My judder is always only on an incline. Smells a bit on a steep hill start as well

changing to a fixed solid flywheel will shake so badly ( i know i did this to a certain model vehicle as there is kit and never again there is no control) my leg was shaking so much trying to balance and control clutch on short stops and the vibration would shake the gearbox to bit as it did on this vehicle

[PatrickM]

You must have gotten an out of balance Flywheel, It shouldnt do that.

I know that we actually put single mass flywheels on cars with Dual mass stock. We do it because people are complaining of clutch judder. We do this on a few Toyota models and that is of the advice of Toyota.

[IS 200]

Wow this problem is really well documented then. I will be changing the flywheel at my own expense. Does anyone know if that will fix it then. Or will it just be a waste of time. I am really not into the welding into one bit.

Cheers

[ChrisIS200SportTTE]

Waste of time in you replace it with a Dual mass flywheel. It's the DMF that makes it judder, even from brand new.

[IS 200]

oh i see. so is the welding suggestion the only solution then. would you say?

[ChrisIS200SportTTE]

No you dont need to weld. You can replace the dual mass flywheel with a solid mass flywheel

[ChrisIS200SportTTE]

All pointless in my opinion tho. I don't know how bad your clutch judder is but mine isn't bad enough to think about replacing parts.

[IS 200]

thank you very much for your help with this. I will try to live with it. Cheers

no imbalance just a terrible problem with solids against dual mass change over

toyota issues were fixed at many points judder etc but we found that changing clutch makes helped eg euro spec back to jap spec products made 75% of problems go away and that was over the last 30 years i been doing this.....................

Not sure if its the same thing as uz are talking about,but mine duz it going into 2gear too? Its a bit like a learner driver lol kangaroo petrol? Makes it look like I cant drive it haha
