Creaking from Peugeot 5008 2012

mickger844posts

I had a fairly loud creaking noise from the front of my 5008 which was heard over bumps and on the flat so brought it to a local Garage. They said the shocks were gone and needed replacing which i got them to do.

When i got the car back first the creaking was more or less gone but the next day it started to appear again.

Booked it into the garage for today but over the weekend not a sound from it so didn't bring it in thinking all was ok only for the noise to return. Albeit the sound is nowhere near as bad as it was before the shocks were replaced its still there to a lesser extent.

It can also be heard when turning the steering wheel and doesn't seem confined to one side.

Any ideas of what it might be. I'll post a video of the sound in question

We had a creaking noise that sounds similar to what you describe in a 2014 Citroen C4, turned out to be the steering rack that was the problem...

Sounds like suspension bushes to me, rubber dries out and makes the same creaking noise as in your video

Would be hoping its the bushes rather than the steering rack as those racks are expensive.

The sound mostly disappeared last Friday after we had rain. It was less today compared to yesterday both being dry days but today was cooler so maybe a factor also.

Would i be right in saying those bushes and that part of the suspension would have a cover over it which would be needed to be removed in order the access them?

Thanks lads for replies by the way.

That to me says it's definitely a bush, if the sound is going away when it's wet and comes back when it gets dry again.

Bushes are just a rubber dampener in between connecting parts of a car, you'll find them anywhere there's two metal components being attached to each other.

Could be control arm bushes, sway bar bushes, that's for your mechanic to figure out.

The front section of the car would be covered underneath with plastic trims, but the wheel side suspension parts are exposed to the elements

this as well, my car creaks as well

First thing to try is a good dose of WD40 onto the shock tops under the bonnet.

I've seen a few French cars suffer from creaking and squeaking from there. Had one a

few years ago where I swore the noise was coming from behind the glovebox, turns out

it was dry rubber in the shock tops. Cost you nothing to try.

Will give this a try tomorrow and see how it goes.Would a Silicone lubricant spray do a similar job?

Yeah, silicone lubricant would be better really. WD40 is a water dispersal (WD) oil, so wouldn't be ideal.

I would have thought a penetrating fluid like WD40 or GT85 would be better?

It's actually recommended not to use it on rubber because it's a petroleum based product. It will work at first, but over time will degrade the rubber.

Been using it on squeaky shock tops for years with no issues.

May depend on the composition of the shock tops. Everything I've read says it gets absorbed into the rubber and causes swelling and eventual cracking. Also great for attracting dust and grime.

Best to use silicon spray. WD40 make that too.

Sprayed some silicone lube around the shock tops which wasn't an easy task in itself. A long nozzle was required as access from directly above was not available. We will see if it makes any difference. Hard to pinpoint what conditions its worse in. Drove the kids to school this morning and it was there and 10 minutes after dropping them off and driving again it was mostly gone. Will be driving a bit more tomorrow so will see how it goes.
