Concrete blocks attached to rear suspension of Pluriel

Hi people,
My wife's Pluriel 1600 Sensodrive possesses these beasts. I am not sure what they are for and the internet is not very forthcoming with info about them either. But they are rattling and the last thing I want is for one of them to fall off and hit another vehicle or person.

Is it possible that there is a worn bush in side them that I could replace?

Does the car really need them?

Would be very grateful for any info.

John

Hi John

Can you take some pictures of the parts and attach them to a reply please?

The instructions for adding images to the forum are here - How to attach images to the forum


Did you read the rules at the top before posting?

Why have you posted the same question twice?

Sorry Guru. Didn't realise I'd posted twice. (I have been posting on other Citroen sites, maybe that is why, won't do it again.)

As for attaching pictures, I will have to wait until it gets light to do them.To save time, I know there are pictures elsewhere on this site of the rear suspension which show them just incidentally. If I can find them again I'll see if I can put a link in.

Anyone who has ever worked on the rear of a Pluriel will know what I mean, you cannot miss them, especially the offside one, it is huge!

I KNEW there was another post on this, and not my accidental other one.

Here it is: "Post subject: Weights behind the rear suspension spring"

I do not know how to link to it but using the site's search engine will get anyone to it who wants to look at it.

The OP was asking exactly the same question as me and did include photographs, which is the important thing for you.

If the OP had got an answer I would not be trying to find the answer.

I really am keen to just take them off and go for a little spin to see if I can tell the difference! The knocking noise is so annoying. If the noise remains I'll have to assume it is the dreaded shock absorbers and then test for that.

Sorry I can't help with an answer but here's a link to the topic you found Link

Thank you Missing Lincs,

They are nicely hidden in the Citroen documentation but make an appearance in this diagram as 17 and 18
17 is part number 7251EY - Floor balance weight - left

18 is part number 7252CV - Floor balance weight - right


Looks like they are bolted to the body, so apart from some rusted nuts and bolts, it may be possible to remove them, inspect and refit if they check out ok.

Arfur, thanks very much for your comment and the pictures from the documentation.

I think it would be great if we could all get access to this documentation.

I note that there is another part number 80 in the pictures, which links to the picture, which I would love to know more about, is it a bush, I ask myself. If so, I bet this is the bit that needs replacing. Would you mind awfully looking it up for me?

I have never heard of floor balance weights on any other vehicle. They are so crude it is hard to imagine a company like Citroen actually using them. I also cannot see why they need to be on flexible mounts. Why couldn't they simply have welded lumps of steel to the rear sub-frame, I wonder.

But then there are lots of things on modern cars which seem basically pointless and invented purely to keep some designer in a job.

Either that, or the chassis design was faulty and these weights are a band-aid solution to some problem that occurred. I bet there is a vibration that occurred under test.

Anyway, thanks again, and I look forward to reading your future wise comments.

Yes it would, Citroen recently took down the public access to their information systems

Its just a nut M8 x 125.

That could be the answer

That's ok, sorry part 80 isn't very exciting

Hi Arfur.

Thanks again for going to the trouble of looking this up for me.

There must be something that makes the mounting of these weights springy.

Once the snow is gone I will have another look at the situation.

Why do I get the feeling that one with a dodgy mount will mean replacing the whole shooting match?

I'll try to remember to take pics as I go so others can be informed.

Helpful of Citroen to take access away, isn't it? Pathetic attempt to make us all pay the stealers to do things we could easily do ourselves, I suppose. Money coming first while human decency follows a long way behind. Fortunately people like you and others on forums like these go a long way to making up for it. I'd be lost with my Land Rovers if it wasn't for forums, a lot of the time.

Cheers!

I think you will be right. One part number usually indicates its a single unit and not designed to be repaired.

Yes, please. Pictures of the procedures, part numbers, part prices and all those useful tips can help others decide if its worth tackling
