Hi David,davidc wrote:Just looking at this thread perhaps someone can advise. My Estate rides like a truck yet have regassed spheres, good rear arms, new accumalator and overhauled regulator etc but still rough as. Today in desperation I checked the sphere numbers and found they aren't on the sphere chart mentioned here! The numbers are front - 96199318 rear 96239028. All are chevron stamped. Anyone know the story behind these numbers?
cheers

Check my sphere charts here:

These are the Citroen part numbers, and both your spheres are listed here on page 4, and they are the correct type numbers.
Therefore poor ride would be the condition of the spheres, or something else in the suspension.
Is it only the front or rear or both which is riding poorly ? Can you describe in what way the ride is poor ? (Bouncy, or wallowy, or harsh ?)
If you let the car lift to normal ride height and then press down on the rear bumper are you able to press the suspension down to the bumps stops very easily ? A weight as little as 20kg should be able to bottom the suspension. (Before it corrects for the load)
The front will feel roughly twice as stiff but you should still be able to press it most of the way down by pushing on the front bumper with two hands or sitting on the front with the bonnet open.
Is the ride height in fact correct ? For a quick and rough check of the ride height check here:

If the ride height is more than about 15mm out either way it will certainly contribute to a poor ride, especially at the rear and especially if it's in the too low direction. (It will hit the bump stops a lot especially at the rear when accelerating)
Does both the front and rear correct accurately to changes in load ? If you get an assistant to sit on the boot and bonnet tray (bonnet open) and you measure the ride height before they sit on it then after it has corrected for their weight, and then after it has corrected after they got off, and it should be consistently within +/- 10mm of the same height after each time it has made a correction.
