Hello again,

You may be better off just replacing the unit. If you do decide to disassemble it, remove the bolt on the end (10mm I believe) and pull the guts out (it will pull hard due to the o-rings sealing the inside). Clean thoroughly with carb cleaner. Apply petroleum jelly to the o-rings before reinstalling. You also stated that you replaced the timing belt 3 months to this. I am assuming that the problem just now developed, not shortly after the belt change? As I said, the solenoid is the usual culprit, but I make no guarantees. I have never seen a problem in the hub itself. As you figured, the solenoid controls oil pressure to the hub. The hub then acts as a worm gear to vary the timing. Anyway, let me know what else you may need. I am happy to help.
