that totally depends on whether some idiot put them on with something like a chain wrench!! which alot of non citro garages do because they dont know what they are doing with these systems. i have also previously had serious problems getting them off. ended up welding a kawasaki motorcycle chain to a socket.

At my last MOT they failed the accumulator because they decided it was leaking. I knew the sphere was ok because it wasn't clicking fast, but I let them change it anyway to get the ticket and I asked them to keep the old sphere for me --- I knew that the accumulator on my other SORN'd BX was knackered so I could put the old one on there. When I eventually got around to installing the salvaged sphere, I found that not only could I not get the knackered sphere off, but I couldn't even get the new sphere off my recently MOT'd BX. I broke a Halford chain wrench and I also broke a Machine Mart socket-chain wrench. The MOT garage agreed to break the new sphere for me so I took it back but they couldn't even get it off themselves. They had used a large articulated pliers to tighten it when they put it on, and they couldn't get it off even with two people trying to work the pliers. In the end I hired an industrial strength chain wrench from Brandon Toolhire for an afternoon for £6 and this did the job with me using my full strength with my feet jammed against the cross member for purchase. The chain was so thick that I only just managed to get it around the sphere in a diagonal direction.

Yep, broke two of those and the spheres do not have to be ultra tight either. A heavy duty strap wrench works better. My Cit guy has a hand made tool made out of metal bar that can be bolted to clamp the circumference of the sphere.
Removal of the accumulator sphere is easiest achieved with a club hammer and chisel on the weld on the sphere circumference.
Huge thanks to Bandit,
not only did he have a pair of front spheres that he wouldn't take anything for,
but he even fitted them for me !.
now the front end no longer feels as if it has concrete suspension.
the guy's a credit to the club.
it was great to meet and chew the fat.
and one fact is sphere's should only ever be put on hand tight not with tools!! 
Well done that man
