Help - I've got a clunking noise!

[Drummer]

Took my LCR to the dealer last week complaining of an intermittent clunking noise/ vibration coming from my clutch.

It doesn't happen all the time & only when in crawling traffic or pulling away in 1st gear, just at the biting point.

You can feel it pull/ clunk through the drive shaft and pedals.

(there is no pattern to when it happens)

The dealer blamed the brakes (new car, done 500 miles) and to that, copper greased the callipers but this hasn't fixed it.

Any help with this would be appreciated so I can go back to them informed.

Cheers

Had similar issue it turned out that the fuse had gone for the cooling fan.

Thanks for the reply Si

To be honest, I don't think its to do with the cooling fan as the clunk happens when cold aswell as hot.

Any more ideas guys?

Hi drummer, I have the same noise in my car. i noticed it when i was holding the biting point at a set of lights on a hill. its like i can also feel the vibration on teh clutch pedal too.

said to the stealer "can you hear that". he said "hear what sir". any way, he heard it and got it checked at the garage. they found nothing wrong with the clutch and said it may just be the car needs driving in as it was on the forcourt for a month. Cars done 5000 miles so far

Hi Diddy

Has the noise gone from yours now or is it still there?

I have done a forum search & seems like a few folk have had similar problems, from missing bolts, dog bones probs, brakes etc.

This is my 2nd LCR, the first one never had this noise/ pulling feeling.

I may just book it in again

Get a torque wrench get under the car and check the front dog bone mount bolts mate even a bolt that needs nipping up by 90 deg can make a clunk that can be felt through the pedals and heard. Might not be but its worth checking they are done up to around 30lbft

hey drummer, the noise is still there. but it goes once the car is warm. odd one really, i think il pop it to the dealer again.

My clunk is still there & I now get a clunking/ rattle noise from the engine bay when I come to slow down then stop?!

 

[Drummer]

Arrrgh!

The clunk, when moving off in 1st, is still there but not as bad

The rattle/ clonking from the front seems more pronounced when slowing & going round corners & when engine is cold.

I've done a big search & come up with this lot!

Wheel bearings (but only done 700 miles?)
cv joint
drive shaft
fly wheel
front anti roll bar
dog bone & bolts
brakes / calipers
gearbox
clutch

I am no mechanic so haven't got a clue what to put infront of dealers nose when the car goes in (the noise is not there all the time)....

HELP!

i would guess you should take that little list to the dealers and ask them to check all of them....

Hi Diddy

I did just that today!

They phoned at 4pm, can we keep your car another day sir?

I guess the bloody thing is in bits with lots of head scratching going on

I will let you know the answer....

Cheers

 

[Drummer]

The car has been with the dealer since last Thursday...

....They have just phoned, can we keep it another day (Tuesday)

They think it's the PAS pump?

 

[Drummer]

Update.....

It needs a new gear box!!!!!!!!!!!!

The car has done about 700 miles

What next?

My car makes the same noise.

Usually when holding at the biting point, of course you only do this when starting on a uphill stretch.

Mine seems to make that horrible clunking noise when revving at about 1,000 to 1,800 rpm, after that it goes smooth again (not just muffled by the engine noise). It's be surprised if it where tracked down to a loose/rattling part, it sounds more like a cog or something slightly mis-aligned IMHO.

I'm not experiencing any other problems at the moment so I just try to avoid it as much as possible. If anyone else has this problem and gets it fixed, please let us know.

 

[Drummer]

Good news!

Gear box replaced....Clunk gone

It was the diff' that had gone, because the car had only done 700 miles SEAT technical told the dealer to replace the whole box.

The old box is going back to the SEAT workshop for a post mortem.
