so I really wanted my cruise to work went through everything I could do to test it.My fix not sure which one did it but I reglued the solenoids back to the accumulator and silicone sealed the bellow on the ends and surprise it work like new every time hope this helps someone.

 

I think sealing the bellows is the important one to do. I need to do this because I had a brain fart and without thinking, squeezed the bellows together and now my cruise does not work. I must have broke the seal. Why did I do that? LOL. Stupid.

 

Uro Parts makes the replacement bellows also. I got one from Rockauto.com, P/N AEU4090. It SHOULD seal without sealant, but whatever works.

 

I agree it should, but I used brand new bellows, new solonoiod seals and replated metal components in my rebuild and still required sealant before it would work consistently. A very small bead around each end does the job.
