Re: Rear Left Suspension Bucking
The cleaper sphere options may have older diaphragm technology that does not have the same service life.

Re: Rear Left Suspension Bucking
It doesn't help that some parts depts are shut due to COVID, struggling to find the correct part as those part numbers:
Rear Corners:
OEM Original Part: 1638045680 £143.18
Cheaper Version: 1638376880 £54.90
The closest I can find is this part that looks right and apparently fits my car? https://www.onlinecarparts.co.uk/suplex-10190726.html
Or
https://www.ebay.co.uk/i/121498365737?c ... VjEALw_wcB
There seems to be many different versions of these spheres it's mind boggling
Thanks, Mike

The expensive ones are the brand new originals as fitted to the car at new. They should provide a long service life.
The cheaper ones are supplied by Eurorepar - these are re-used units, hence the cheaper price. But don't ask me what the quality is like or what they actually do to them - whether they just re-gas them or whether they repair or replace the diaphragms I can't say, but Eurorepar are used by PSA to provide lower cost parts for older cars.
That’s interesting about the spheres, and without hijacking Mike’s thread (It may be helpful for future forum searches to find more about this in one thread), my ride quality has slowly but progressively been getting worse for the past year, though not as bead as Mike describes for his car. Mine’s just lost that lovely, fluid ride it had when a I bought it (now on 85k miles). Bouncing on each of the four wings makes that corner move up and down though the OSF is a little stiffer than the nearside. Perhaps Ill wait for it to get even worse to point me in the right direction!
Cheers

Re: Rear Left Suspension Bucking
Mike, my ride quality sounds similar to yours, and I’ve noticed it getting progressively worse over the past 12 months or so. How long have you noticed yours getting worse, or did it just appear instantaneously as a problem?FlyMike_88 wrote: ↑23 Jun 2020, 20:37 Evening all,
I'll try and describe this as best I can!
My C5 X7 Exclusive Tourer (83k miles 59 plate) rides very well on the motorway and over slowly undulating roads, soaks them up like no other car I have owned. When I slow down and go over a speed bump or similar bump in the road, I can feel the rear left of the car almost buck. That side goes completely firm and I can feel it in the car. I'm going to get it up on the jack tomorrow but any initial thoughts on where to be looking?
The car raises and lowers seemly okay when operated with the buttons.
I've read a little about checking the height correction adjuster and possibly changing the sphere on that side?
Thanks for all the help so far by the way, very useful resource this forum!
Mike
Can you bounce the car on the four corners (like when testing the dampers on a conventionally spring car) , and does one appear harder than the others?

Re: Rear Left Suspension Bucking
I've only had the car for a month but I noticed it almost straight away. If I go over a speed bump, the front is nice and smooth as is the rear OS. When the rear NS goes over the bump, it stiffens right up and puts the car all out of balance and upsetting the ride. I'm almost certain the sphere has gone on the rear NS.
Each corner bounces smoothly when I put weight on them stationary (engine running), it seems to be only when the suspension is asked to absorb at a quicker rate (if you know what I mean).
Thanks, Mike

Re: Rear Left Suspension Bucking
A rear corner sphere down on gas pressure will jump/bounce over a sudden lump.
A sphere of the wrong type (eg one with much tighter damping/smaller damping orifice) could also react badly to a sudden change in road surface.

Re: Rear Left Suspension Bucking
Swap the rear tyres one side to another before you do the Sphere, make sure its not tyre related first.

Re: Rear Left Suspension Bucking
Hi all,
I am still have trouble narrowing down what part to order for the NSR Sphere. The part numbers 1638376880 and 1638045680 show up as the whole shock absorber when searched online?
Any help appreciated
Thanks, Mike

Re: Rear Left Suspension Bucking
In the past I have used AEP Direct when ordering spheres for my Xantia. I cannot say how good they are for C5 spheres, but I never had any issues with the spheres I ordered. I have no links to AEP Direct;
http://www.aepdirect.com/
If you do order parts from them, make sure to give the full vehicle details (so they can check you have ordered the right parts for YOUR vehicle), otherwise they will contact you for them, and this could add a delay to dispatch of the parts.

Re: Rear Left Suspension Bucking
Mike, I wouldn't recommend a used sphere to be honest. Searching scrappies may well bring up the strut too, as they are not always inclined to separate these (not only will this be difficult to do when they are off the car, but is messy). By the time you have managed to separate it (if you can), you will have no idea what condition it is in to be honest, plus the cost of LDS fluid when replacing it makes it a risky job if you have to do it again.FlyMike_88 wrote: ↑13 Jul 2020, 18:13 Hi all,

Best you get a new replacement and if I were you as you know it will be brand new.

Re: Rear Left Suspension Bucking
I would also (unless the cost is too prohibitive) replace both spheres at the same time. That way you know you will have a smooth, consistent ride across the 'axle'.

Re: Rear Left Suspension Bucking
I’ve ordered a couple of new front spheres which should arrive tomorrow. I don’t have Lexia so will use the above procedure shared by Marc (Thanks Marc).GiveMeABreak wrote: ↑30 Jun 2020, 14:56
B) If you don't have a kit, you can manually depressurise the front or rear axles independently, depending on the spheres you are replacing.
Disconnect the battery.
Raise the vehicle and support on axle stands, wheels free.
You will loose fluid, so don't re-use any reclaimed LDS that comes out, so make sure you have sufficient new LDS fluid to hand.
BSI Reset / Battery Disconnect / Reconnect Procedure
How to remove the existing sphere? Is a special tool required or could I use an oil filter removal chain wrench, or a big Stilton wrench perhaps?
Also, is there an O ring seal fitted so I can buy new ones before starting?
Thanks

Re: Rear Left Suspension Bucking
Hi Steve. You will require a new large o ring seal - these usually come with the original spheres, but if you getting another brand, you'll need to check. As for removal, yes a similar sort of tool to a chain wrench, but as the shape is saucer;like, it may have some problems staying on. I think Elis put something between the sphere body and the wrench to give the chain a bit of grip and to stop it slipping.
