Bouncing test for central hydractive spheres

Post by Juliso35 »

Hello

Nice to be here again. I have little doubt!!!

There's a simple way to know the condition of central Hydractive spheres? The bounce test on the corners is the suitable for themselves, but how to distinguish which of the three sphere per axle (hydractiva) is not in good shape.
I.e the corners spheres are very well, how can be noted that central sphere is wrong.

Regards

With the doors shut and igntion off for over 30 seconds push down on each corner then open a door and do the same push test, with the doors open the suspension should be softer.

Hi DickieG

A flat hydractive sphere could affect tick rate? This test you said should valid if height correctors and EV's are fully OK and non leaky right?

There is another way in case of failures in these two components? Just testiboules :(

A flat sphere will have some effect on tick rate as the sphere membrane will no longer have the ability to flex, how much effect a flat Hydractive sphere will have on the tick rate I couldn't tell you.

For the test to be effective yes the car needs to be at the correct height, if the electrovalves are stuck open or closed then no difference will be felt between tests.

I can't think of any other ways other than using a sphere pressure tester.
