Clunking noise from gear change mechanism

[ex-Chinese Dave]

As you may know I’ve been chasing every noise on this car since I got it. There is this strange clunking noise that I hear went on and off the throttle very very gently at different speeds, and also when I am changing gear. The gearbox has been refreshed by Mark so I know the internals are fine. However, I have looked under the car and there is nothing loose that I can see apart from the gear change mechanism. Obviously this has to have movement but just look at this video and see if this is normal, which I suspect it is, and also if there is anything I can do to reduce the amount of play if it is not. The clunking noise also happens when I am about to stop the car but I don’t dip the clutch as normal. The vibration from the engine almost stalling makes the noise happen quite loud. As the mechanism is the only loose thing under the car, I’m sure it has to be this. If this is not normal then is there a way to reduce the amount of vibration, movement here? It also had the new brass bush fitted to the selector when the gearbox was re-fitted.
This is one of those irritating noises that I would not be able to put into a video as you just wouldn’t hear it. If someone was sat in the car with me, they would obviously hear it. Or maybe this car just is making me paranoid.😱

I tried to see if there was anything I could do to dampen the movement and hopefully get some kind of result to point me in the right direction. There is nothing I can do that won’t restrict the movement of the mechanism. I did notice that the spring, near to where my hand is, is possibly weak. There is a shaft that goes into the gearbox and I think that when you put it into reverse gear, the shaft moves up and down. The spring that is there seems to offer only a little resistance, meaning it’s very easy for my hand to push the gear change mechanism upwards. Is this spring something that can be upgraded? If so, I guess that that would hold that shaft in the down position for changing gear but would still allow the movement to put it into reverse. Am I making any sense here? Or should I just go back to bed?

That selector noise is normal

They do clunky into gears. The only place they would have play is at the red bushings under the shifter tower. But if they had that much play you'd be struggling to get gears consistently

I would look at balljoints/lower arms/rack bushes personally. That's going to be the most likely cause if you've replaced all of your engine mounts

The spring on the selector is purely just to keep tension on the selector arm so it doesn't just slop around and the shift feels more direct

 

[ex-Chinese Dave]

The ball joints, track rod ends and ARB are all new. We didn’t replace the two bushes in each wishbone due to time but there is no suspension knock from anywhere so I doubt it’s them. They look in good condition.

Is there anything under the gearstick itself that can be replaced or adjusted?

Did it does those noises before all the work was done?

When I first bought the car it felt pretty tight but the more miles I put on it the looser it got. It had only done 1.5k in about 11 years so time caught up with it pretty fast (hence all the new bits). I'm fairly sure this noise was always there but I couldn't distinguish it from all the others. Take that squeak for example. You could not hear that until the suspension was refreshed and after it drove me mad. Turned out it was a worn top engine mount and even fitting a decent used one solved that. Drive over speed bumps and uneven roads and you don't hear this clunk, but curl your toes on and off the gas pedal at 35 and you can hear it.

It's frustrating that it will be something and nothing. The last noise that annoyed me turned out to be a worn top engine mount.

Was it a squeaking noise, when you were going over speed bumps etc?

 

[ex-Chinese Dave]

Driving home tonight on a smooth road surface (yes, there are still some of these left) I can make the noise happen if I dab the clutch a little when traveling at 30ish in 4th and 5th gear. It’s had a new clutch pack when the gearbox was fitted so surely it can’t be that. I really need to get the car back on the axle stands and have a good fettle but I’m still leaning towards gear linkage being the cause.

 

[ex-Chinese Dave]

I’m sure I’m boring the forum with this now….

I’ve noticed that when the car is cold, before it gets up to temp, I don’t hear this noise as much. Probably just me but I thought I’d just add it.

(Disclaimer: “It’s 22 years old, just turn your f***ing radio up!”)

Check the balljoints haven't come loose and ovalled the wishbones

Or that the subframe holes haven't ovalled

It could literally be anything

 

[ex-Chinese Dave]

"It could literally be anything" totally explains my car lol

It just passed an MOT last week with no advisories. I just know this will end up being something stupid like someones left a hammer on top of the exhaust!

After a bit of searching I found this old link on here...

Parts diagram needed for Gear linkage

I need to find some parts diagrams if possible of the gear linkage from and including the selector arm all the way the the shifter, Does anyone have any? Part numbers for the parts would be ideal also! Thanks in advance :) James

cliosport.net

It contains this video...



From 4 to 14 seconds the sound this chap is getting is very similar to what I hear. I think the video maybe from a phase 1 car but the sound is almost the same.

I'm going to try the easy idea first and change the gear selector spring. I don't know if it's well worn but I can easily push the mechanism against it with little effort. I think this is the correct part...

Is there anything else I could change on the linkage that may also help?

I also think that the hook on the longer piece is missing from mine as it is just straight. Maybe it's an earlier part and is meant to be that way but Christ knows.

The selector return spring might have rusted. They do wear away too

I had one the other week that was basically paper-thin in one spot

 

[ex-Chinese Dave]

So i'll order the spring from RPD. Is there anything else that I should order that is a DIY fitment job?

 

[Brigsy]

Selector sounds normal to me.

Mine snapped on my orange dci, years ago. Not noticed much difference without it 😅

That's fine, if its just when accelerating it has to be either shafts, hubs, engine or box touching something, get it on axle stands, fire it up and have a mate find the issue

 

[ex-Chinese Dave]

Well, well, well.

Today I fitted the new spring that is attached to the gear linkage mechanism and although on the video it looks like it’s not seated properly, that’s as good as it gets. The old spring was worn and a little twisted so probably need changing anyway. I didn't changed the nylon bush and circlip simply because I didn't have any time if I had ran into any problems. It didn’t feel like there was that much play in it anyway. I checked everything else underneath and I couldn’t find anything loose or damaged at all. I shook the exhaust vigorously and it didn't knocking against anything.

I let the car get up to temp before starting to listen for the clunk and it is way less than before. I'll go as far to say that I couldn't hear anything at times. I changed gear the same way as usual, not too gently but not ramming the stick, and nothing. I did the lightly tapping the throttle at 35 on and off and couldn't get the sound to happen. Possibly solved? Let's see how it goes over the next few days.

If you look at the vid and see where my fingers are you'll know there is a shaft above that which goes into the gearbox. I don't know what is on the inside of the box where the shaft goes in and out but is there a bush or something that may have broken or is there just the spring I fitted that dampens the movement? I have checked everywhere else and nothing is loose. I'm thinking that when I change gear/go on and off the throttle gently and the engine/box rock about then this shaft is knocking/touching the box housing and that is causing the noise. The box has recently been refurbished so i'm hoping that it was just this spring that although it looked ok was worn. I know that Clios are no RR's and there are plenty of noises but this was annoying. The squeaking noise I had a few months ago turned out the be a top engine mount that looked fine, much like the spring I changed today.

 

[ex-Chinese Dave]

After a few drives today and tonight this is 90% sorted. The new spring has definitely made a huge difference meaning the noise is coming from shaft that goes into the box touching the side of the box. Not sure if I can dampen the noise any more but I’ll have a look at a diagram showing what does what and try and work something out. If that shaft was made of plastic it would make a sound, I’m sure of it. I’m also sure it would last one gear change before breaking, too.
