    Dialed-in AHC

    For the first time since owning my '07 LX I have the AHC dialed-in. Holy cow is the ride smooth and comfortable! Potholes and rough roads are gobbled up. If your AHC is original and your globes are shot, it's worth replacing them. New globes, fresh fluid, and t-bars adjusted so the pressures in...

    Jumping Mode for AHC?

    So I just saw a video about MB creating a jumping mode with their hydraulic suspension to free a vehicle from mud or sand. It just kind of hops itself out while the driver feathers the gas pedal. Has anyone tried hot rodding our suspension to mimic that effect?

    Taking care of AHC

    Will my AHC system last longer if i do not use it often? For instance, i can decide to switch it off so that i only switch back on only if it is really necessary. Is this even a good idea?

I am planning on flushing the AHC system but before I do that, I wanna get opinions on what to do first. Currently, there seems to be barely, if any, AHC fluid in the reservoir. I came across...
