Activa dropping at the front

Post by KP »

In the last week my activa has slowly and worsely started dropping at the front.

Initially it was overnight but now if the car is parked up for an hour it drops :(

The ride is soft at the front (the rear has always been stiff) so I'm starting to think that one of the front spheres has punctured.

I had been thinking for a while to go to westroen and get the rear end spheres done but now I'm thinking of taking an afternoon and getting the whole lot done unless I have a really bad strut leakage which I'm guessing I can only tell by taking off return pipes :(
Along these lines does anyone have or know of a diagram showing which return hose is which when they get to the lhm tank?

Mine varies whether it decides to drop on all 4 wheels, the 2 rears or just one corner. I'm thinking the same as you.

David Hallworth (member on here) suggests it's probably a flat sphere somewhere. I was thinking of changing all the spheres as they appear to be a mixture of refilled and miscellaneous spheres on the car.

I've just had a vet's bill so the Activa will have to wait a month!

Well it's £300 from westroen for all 10 which isn't too bad really when I work out it would probably be a day of time for me on my back wrestling some of the worst ones out! I may get under the car and remove the spare wheel carrier though as I know that makes life easier :)

Will, see if it drops in the same way when the suspension is set high. If it then stays up then wear in the struts may be the cause...

Spheres are worth checking but they are unlikely culprits, especially if the front is soft when it should be and switches hard normally..

Anti-sink valves are normally very reliable and can be ruled out of the suspension stays up from high...

I had this exact problem on a 110HDi I had... Checked everything and in the end concluded it was wear in the struts.. It stayed up from high for ever...

It also went on quite happily for 10 of thousands of miles like it.

Drops like a Xantia exhaust backbox when the normal joint rot occurs :D

Drops like the atmosphere in a crowded lift when somebody lets one rip loudly (and, now, like the tone of this post)!

Think I'll just bite the bullet as I know all the other spheres are getting on and the rear corners are gone as in hard mode it's rock hard so will maybe see about comfort rears as well...

At the rear your best bet is Hydractive Xantia Estate ones are best Will... It's what I use on mine.

Unlike Jim, I dislike the under-damped ride given by estate rear spheres, good original spheres are best if you do any spirited driving.

I am also not understanding the theory that a sinking suspension cash be caused by flat spheres. When the suspension sinks, the LHM must be finding its way back to the tank, and I am sure that it isn't getting there via a sphere.

It's French, we know a front blower motor failure can also cause a heated rear window failure... there's no logic to it but when quaffing cheese, garlic and red everything can make sense lol

As you all know, I don't do spirited driving. I love an Activa because I cannot tolerate body roll in any form whatsoever, not for how fast it can corner, so my requirement is for comfort. Estate rears give me that.

Personally, in the case of the problem you have Will, I'd always exclude spheres from enquiries as a first action as flat/ruptured ones can do strange things, especially on an Activa..

As I said in an earlier post in this thread I very much doubt it is a sphere but do check them...

The only other things I can think of would be a scored strut that's allowing leak by as the seal can't seal it properly or the front version of the anti sink valve or such isn't shutting when powered off :(

Looking around and found this...

Now I don't have a leak but was wondering if it could be the culprit?
