 Hi
I had a look at the tech guides (I'm guessing this is the documents you get from Citroen Services for a fee?) for removal and refitting of spheres and they seem to go on about removal (and refitting) of a whole lot of other stuff as well (e.g. for rear strut spheres, it sounds like strut, harness and high pressure piping need to be either removed or disassembled etc).
I had a search but didn't find anything.
What am I missing?
Cheers
Sam

 All you need to do is de-pressurise the hydraulic system, then unscrew the spheres. No need to dismantle anything.

 Don't forget the front stiffness regulator sphere. Replacement requires the front right mudguard liner to be removed.

Make sure you have a stout removal tool. I found the rears especially to be VERY tight (changed after 8 years of service.

 Hi G,
you mention the rusty rear spheres being very tight! I invested in a sphere removal tool a while back and I've replaced all the front spheres for new, but I'm getting around to replacing hopefully the rear ones. I did notice while replacing the rear anti roll bar that it looks fairly tight at the back. What is the best technique to remove the left and right spheres as they appear set back in the rear subframe?

 My homemade sphere removal tool didn't really fit for the outer rear spheres. I found removing the wheels and working through the wheelarch (and dismantling my tool and then reassembling in-situ) made the job just possible! It took a while.

 321Dave,

I think you bought the same tool as me. It will fit on the space of the rear strut spleres.

Best regards,

Phil C.

Thanks Phil, it was I think your suggestion or maybe Niall. It's been great so far!

Hi G,
many thanks for your advice. I'm going to redo the rear hubs soon and hopefully rid the car of the intermittent ABS sensor issues at the rear, I believe coming in part from a small hairline crack on the abs ring I cleaned at a recent brake service. Time will tell if I should have bought better quality replacement sensors.

 Hi Dave, touch wood (tapping my heid), replacement of the two rear ABS sensors permanently cured all the ABS and related warnings.

I used Bosch sensors (about £25 a pair), replaced the rear disk shields which were shedding magnetic debris everywhere and spent some time cleaning everything up.

regards

 Hi all,
I read gmerry's post about his homemade tool (which looks like a heavy duty oil filter wrench).
How is it dexy350's tool sold on eBay different and is it what you have, Dave & Phil? And it's good for all 7 locations? (gmerry was saying rear corners were a bit trickier with his tool?) Do you have photos - eBay photo is'nt very clear.
cheers

 Hello ul9601,

Yes it is dexy350's tool I use. It's very simple. And you can access all spheres with it. The tool head is a band with 3 bolts threaded around the circumference. You tighten the bolts to engage with the centre waistline of the sphere. It can take a few goes to get it to grip but it works and the price is great!

Best regards,

Phil C.

 Hi ul9601,
same for me as well. Dexy350. It as was suggested to me, and I bought it from eBay about year and a half ago. It's been great so far. Thanks again. Dave.

 Is there a timeframe that the spheres should be changed? Only ask as I've no history of them being done on my car and it now has 214k kms on it. Car seems to ride ok so would it be a waste changing them or how do you tell if they need doing?

 Hi Keith,
I think the general advice I read somewhere states that the new saucer spheres never needed replacement or maybe they are guaranteed up to 100000mls?
