The Activa is seriously hard at the rear in hard mode but yes, there should be a little bit of give. Not a lot though. If it's absolutely rock solid then that's another pretty good pointer.
The speed hump test is the same in essence as the hump-back bridge and arguably speed humps are a lot easier to find than a good old-fashioned hump-back bridge these days, at least on you can attack at a brisk pace...
Remember the rear corners demand a special method to start them undoing and can be tighter than a tight thing. A seriously good sphere tool is required.
Yes, it certainly seems to be the case Jim. I'll go have a push down in a minute and see how it is, as it's been left in normal ride height since last night (naughty I know).
And yes I remember the method of loosening them off while on service high, so I'll have to get cracking making a tool up for the job!

That's about right Dom. Spheres are not ruptured then but likely to be about half normal pressure and that's enough to make the rear bounce like Tigger...
It does seem like the offside moves probably 1-2 cm, and the nearside <1cm, not a lot, but it's hard to judge when it's wet as you slide off the thing!
I'll get the rear corner spheres replaced regardless, then I'm sure I'll consider replacing more once I've done the rear ones.
For anyone interested, I used some carb cleaner on the front height corrector today while my brother was moving the height control lever back and forth. Then wiped off as much muck and dirty grease as I could, then used some white spray lithium grease on both the front struts and on the height corrector itself. Surprising what a difference it made as now everything raises and lowers much more smoothly (apart from the characteristic activa side to side movement when raising/lowering), but more importantly the front end raises up as it should from service high or low and doesn't stick.. Which is nice! And I'm pretty certain the front end feels more supple too, which I suppose it should do, so it makes sense.
I did spot a totally knackered inner CV joint gaiter though - I'm starting to doubt my MOT bloke to be honest! Basically the nearside inner gaiter (the one between the gearbox and drive shaft, that is called the inner one isn't it?) is in two pieces. There's been a grumbling sound from down there since I had the car and I assumed it was a wheel bearing, but this could be the cause.. Is there a bearing down there? And if so is it like a cartridge bearing or like a CV joint style bearing??
