Driver's side dropped ... Orb failure?

Hi,



I drove over a (poorly marked) speed hump a little too fast at the weekend and the drivers side dropped, both front and rear. It dropped so much I had to take the mud flap off the front to stop it scraping the ground.



A little history, I've had to pump the driver's side up a couple of times in the last year, but have never seen any evidence of a leak of the hydrgas fluid - ie no little puddles on the ground where I park.



It seems to me most likely that one of the spheres has failed. Is this likely to be a good diagnosis?



Is there a good way of finding out which orb has failed, front or rear?



How big a job is it to replace the orbs?



Thanks for your help,





Mike
