ACTTIVE SUSPENSION REBUILD

[rover3l]

Well I finally got my remaining 5 active suspension accumulators fitted today. The result is astounding. The level of ride and stability improvement far exceeded my expectations. I have now done all suspension rubber plus 9 accumulators. The ride is pillow soft and the handling razor sharp plus the stability over crests and undulations is unreal. I truely can't imagine a better riding / handling combo.

However, after fitting the accumulators there is a noise which sounds like a pump whiring. The pitch of the noise rises and falls with engine revs. It could be air in the system I hope or some other cause that will need fixing. I telephoned Keith Bowers (Texasoil) and we discussed possible causes. Could be something unrelated like an idler pulley or a bearing, could be air in the active pump or could be a worn pump.

I am going to see how it goes over the next few days before investigating further in case it is simply air in the system

A mechanics stethoscope http://www.harborfreight.com/c...41966 is a good investment for tracking noises like that down... I'd do what you said though and see if whatever it is works it's way out in a day or two. Just keep your eye on the fluid levels.

A trick I always used for air in a hydraulic system was running it up and down a steep incline slowly. My driveway here would be perfect.

Congratulations!

I am anxious to do mine and waiting to save the $$. Fuel pump is next on the list before accumulators.
