Hi all,

Has anyone heard this annoying squeak before (see video attached).
I can’t figure out whether it’s from the interior or exterior, but judging by how loud it is, it sounds like something inside. Seems mainly to do it when on the throttle, even lightly, especially when first throttling on after changing gear.

Ive changed the tie bar bushes as they were worn and my mini specialist Colin has changed the top engine steady bushes.

I know it’s a mini, but this squeak is quite annoying!

Any help much appreciated

Duncan

Thanks, should be visible now!

Sounds similar to the noise I've had.. Turned out to be the Front Suspension knuckle joints

[phillrulz]

Lots of things , id say check out engine steadys the bulkead one mainly, front subframe tower bolt mounts , front suspension in whole subframe floorpan mounts?

My car is so noisy, I wouldn't be able to hear s squeak like that.  Makes one wonder what else I'm missing.

the cheep cheep noise?

[dunkyb]

Monkeymonk - I cant hear the noise if I bounce the car on its suspension so wasn’t sure it was suspension related, but could well be.
There’s a bit of rubber at the bottom of the trumpet which has come off and is just sat on there, but not sure of that could cause it.

Phill - bulkhead Engine steady bushes replaced - Any tips on the other bits?

Yep it’s the cheep cheep noise I’m trying to hunt.. does sound like a bird in the car with me.

That's the cover for the ball joint - should be located over the top edge of the plastic cup that sits in the top arm.

If it has been dislodged for some time there is a good chance the grease in there is dry, crusty and contaminated; at worst the cup may have worn through, resulting in the knuckle making metal to metal contact.  This could be the source of your squeak (if it was worn through it would likely be much worse though).  They're cheap and whilst a little involved to change (need a suspension cone compressor) it would be well worth it.

Thanks guys. The odd thing is if i coast along, even over fairly bumpy ground, I can’t hear it. Only when I go on the throttle. Pretty much have to have the throttle engaged, albeit lightly.

Perhaps it’s a placebo effect and it only puts enough strain on the suspension when accelerating, but feels more like a ‘forward motion’ rather than ‘up and down’ motion that causes the noise

This is the piece of rubber I was referring to at the bottom of the trumpet....

Yes - a very perished knuckle joint gaiter.  

Looking at that, I suspect that joint is very dry inside.

[dunkyb]

That rubber actually pulls off completely!  Looks like someone may have cut it to fit on, not sure it even looks like a genuine part.

Could I pop some grease in there for now and hope it works it's way in?   Looks like that knuckle joint is going to have to be replaced soon then and could well be

the source of the squeak

[dunkyb]

I think I found the source of the squeak.  Believe it or not, it's the towing eye rubbing against the metal on the frame.  I sprayed some WD40 on it and the noise went away.

Could easily hear it when pushing on the front bumper.

 

Is it normal for the towing eye to be touching, and can I adjust it so there's some clearance?

Thanks!!
