Hello ladies and gents,

Would anybody know if the 6 spd manual transmission on this engine (same as fiesta ST trans I think) has a peep-through hole where I can check the clutch assembly in the bell housing? I'm getting some nasty knocking sounds and I think I've narrowed it down to the clutch assembly. The noise seems louder up by the turbo but seeing as driveability was unaffected in my 1500 mile drive back home through the Colorado mountains, I don't think it's turbo related.

Symptoms: Really bad knocking sounds and the engine shakes like crazy but when I clutch-in the noise is gone. Once the RPMs go above 1000rpms, whether cruising or just pressing the gas while at a stop the sound goes away too. Drive-ability seems unaffected but I was in the middle of a roadtrip 1500 miles away from home before the noise started (drove the 1500 miles back without an issue.) Car is currently on stands and nothing looks broken from what I can see. I've had a similar knocking sound, but 10x quieter, since ~30,000 miles but I never thought anything of it since the car drove the same.

No modifications, car has 180,000 miles on it. I just got an oil change before the trip (~2000miles on oil + filter). Oil is still pretty clear and isn't milky.

Engine shakes? Do you have a broken engine or transmission mount?

That was the first thing I looked for but they all look intact.

Looks like there's a pressure plate recall for my car. Looks like I'm in luck, I'll just bring it in and get a new clutch assembly and hopefully that solves my issue.

There is probably broken/worn or loose spring on the clutch disc or there are some worn/broken fingers on the pressure plate.

Which engine do you have? 1.0? The 2.0 NA only came with the MTX75 transmsision. Unless you have the ST 2.0T or 2.3 (1st generation US) , that is.

Either way, my old 2011 Focus 2.0 5 speed always had that rattle in the transmission. I was always told it was gear rollover noise, whatever that means. That's also the cause for the rattling in my ZF 5 speed 350 transmission when the engine is lugged down.

Edit, just watched the video. Could it be a problem with the dual mass flywheel?

While I don't have any vehicle specific knowledge, that sure sounds like a flywheel/clutch/pressure plate problem.

Typically when the clutch springs break, there is a buzzing sound upon a specific level of acceleration or deceleration. Along with a knock at idle when the clutch pedal is not depressed.


People who count on their fingers should maintain a discreet silence.

Yep it's the 1.0L with the 6spd manual.

Thanks for the replies guys. The video is exactly what the noise sounds like. I may have just dodged a hefty repair with the recall.

A really common issue with VW/Audi cars, the turbo engines can really tear them up in a hurry if driven with any enthusiasm, the only real fix is a single mass flywheel.

That's good to know, I never knew something like that existed. All the clutch issues I've ran across were from broken throw out bearings or clutch forks.

Hi folks, an update:

So the dealer won't cover it under the recall because it passed the "clutch slip test" but they did say the flywheel, TOB, and the bolts are all damaged. They'll replace it all for the lovely price of $1020. I really don't have any other choice since the backup car I'm using has summer tires and I do NOT want to be driving that in this freezing weather (plus snow/ice.) I'll pay it at the dealer but should I contact Ford for a [censored] statement to see if they'll reimburse me, maybe part of the cost if not the whole thing? The description of the recall is down below. What else should I do? Can I ask the dealer for the damaged parts back in case Ford corporate wants to see them?

Search that recall number on NHTSA, theres some interesting reading in the documents.

I feel like I’d be on the phone to Ford and NHTSA... If it is under a recall for a defective pressure plate and they’ve determined it has a bad pressure plate it seems a bit irrelevant whether is passes a slip test or not...

On the other hand at 180,000 it might just be worn out In which case it seems like it would fail the slip test.

Very interesting result from the dealer. I have the same car (Focus 1.0 / 6M) and just assumed that recall was a new clutch assembly and new programming - no questions asked.

I’m at 85,000 miles and was just planning on waiting until past 100,000 miles, to get the most life out of this clutch I can. I doubt I’ll ever “wear it out” though.


Whatever's on sale...
