Creaking Noises from 307

I have a 307 which is giving creaking noises from the rear on one side. It
is worse in the morning when setting off for a few miles and gradually
seems to get less during driving.
The dealers have changed a door striker and one of the suspension parts
but I still cant work out where it is coming from. I have ruled out:
Spare wheel and tyre
Boot floor
Seatbelts
Seat backs
I personally think it is suspension related - especially as it seems worse
when cold and improves over time - almost like it is loosening up. Any
ideas?
Has anyone any ideas or had any other problems with the rear suspension
that sound similar? Or has anyone else had a rear door striker changed to
fix a noise? It is driving me up the wall and the dealership has no other
ideas.
Thanks in advance

 

307cc 2 months old - same symptoms = F/N/S anti roll bar bush (noise did
come from the rear!) - identified by dealer and replaced under warranty -
problem solved

 

Thanks for the reply. Unfortunatly I had the anti roll bar fix done to the
front a while ago. Are there anti-roll bars on the rear too?
What do you mean by F/N/S?
Anyone else got any other ideas?

 

F/N/S = Front Near Side.

 

Mine was doing that too. I told the dealer it was coming from the nearside
rear door, which is what it sounded like, but they traced it to the
hatchback closing mechanism (whatever you call it) and adjusting that has
cured it. Now, I wonder what that crunching sound from the rear suspension
is when I go over speed bumps...

Thanks. I must admit I don't think they have looked at the rear hatch
closer, and its not something I have thought to check.
I personally think the 307 suspension is very noisy generally but dont
know whether it is just my car or whether they are all the same.

 

The usual cause of creaking is from the doors. The aperture seals dry
out and slight movement of the doors when going over bumps or round
bends makes a creak. Push the door when it is closed and see if there
is any movement inward and if there is adjust the striker inward to
tighten the door on the seal. Don't go too far with this as there will
be a gap beween the door and the wing. The the seals can be
lubricated. There are solutions on the market for this, OR you can use
what I did the other day--furniture polish! Sprayed it on the seals on
all four doors and the tailgate, leave it for 15 minutes to soak in,
then wipe off. I also put a small amount on the striker and the lock.
Worked for me.

 

Mine has very noisy rear suspension, like a van. The ones they've loaned
while it's being repaired have been just the same.

Happens also to me, it's probably the top of the suspension that hits the
plastic of the car. The solution is maybe to put some smaller screw on top
in stead of the original one.
