I have my driver, and a parts car that both have SLS. If I remove the 4 spheres will it be obvious if any of them is OK? I searched and someone mentioned that you could put fluid in them and see how much fluid each one takes. If I have 4 bad or 4 good, how will I tell? Do they take a lot of fluid when they are OK, or...?

Thanks,
Tad

The accumulators should be pressurized to 15+ bar. I believe they are 23 bar when new. You can't pour anything into them unless they are busted internally. You need to measure the pressure at which fluid starts to pump into them.

That line right there should be enough for me to at least get some idea of their condition. They might not be as good as new, but if the diaphram isn't ruptured I'll at least have a starting point for a rear suspension.

Thanks,
