i wrote the wrong word here So what kind of damage could be done to the pump? i meant VALVE i don't buy that about the bad spheres causing valve problems but we shall see... when i bought my car years ago, the spheres were bad and i didn't replace them for a month or two, i'm sure then

So I went to a dealership for a Club High Mileage event and had an array of seasoned techs work on my suspension problem. :) The consensus was that the bouncy rear end was NOT related to the air cells (spheres), since they are new. We lowered the ride height by adjusting the rear valve linkage,

Andrew, From my experience with SLS, I believe that you've got leveling valve issues. Here's my logic: If changing the leveling valve settings causes the suspension height to change, the struts must be good. If by some chance they were bad, it wouldn't raise at all, assuming the seals on the

It pounds the base pressure and overpressure relief valves and their springs into oblivion. It will eventually also cause strut seal failure, lower balljoint failure, and top strut bushing failure. On Apr 19, 2014, Rick Hawkins wrote: i don't buy that about the bad spheres causing valve

Sounds like they further misadjusted the linkage. The valve is working if they were able to influence the resting height. The system's operation is clearly described in 32-501. It should be adjusted so that the unloaded vehicle's resting height is determined only by the base pressure. The

One thing also to look at it, and I presume your mechs did this, is the condition of the plastic bushings on the turnbuckle linkage. If those are not solid or are missing it will not allow the system to function properly. Have you ascertained if the pump is actually pumping pressurized fluid

Since I installed new spheres it rides less harshly. I don't notice excessive bounciness, but it fails the bounce test at rest (won't recover quickly enough after pressure is applied to the rear bumper). David: Are you saying that all components are sound, and that applying 32-501 will solve my

If the springs are too stiff the suspension will ride too high, and you'll never get the system adjusted into the proper range. -- Jim ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery
