My 99 rides pretty hard, none of the cloud ride I hear about, lol. I've had it about a year and always assumed it was the globes, even though the system is "healthy" per the self-diagnosis stuff you see (7-8 gradations between high and low on the reservoir). I should probably take the ol' Techstream cable to it and make sure nothing is stupid off base with pressures, but I'm pretty glad to see the globes around $500-600 a set instead of $1000. A $500 once-every-22yrs maintenance repair is totally doable- that's about a car payment. A grand is tougher to swallow, mentally.
