Before anybody slams me for creating yet another AHC thread, please know that I have searched for weeks and not found anything on this specific issue that I am having.
History:
I have a 2001 LX470 with 299K miles that the dealer replaced the front AHC globes on at 265K (12/05/2017). Around two years ago, I replaced the rear AHC globes at 293K. The vehicle drove smooth for the last 2 years but I now have developed a pogo stick front end. I have flushed the system several times but ride is still harsh. I am getting about 6 graduations on the reservoir from L to H, which I think means the globes are likely bad.
Pressures:
Front = 6.4MPa
Rear = 6.1 MPa
Issues:
1. Poor ride quality in front only.
2. When flushing and bleeding, I am getting nice fluid out of each globe actuator but the accumulator continues to have air and poor fluid appearance (grey). Also, when bleeding the accumulator, I start to see some very small rubber diaphragm debris from the old globes (I assume) followed by an abrupt stop of fluid evacuation.
Questions:
1. Is it likely that the front globes need to be replaced again?
2a. Is it normal to have the accumulator just stop flowing or should it continue to drain the reservoir?
2b. Could this cause dampening issues in the front only?
I have ordered new front globes from Cruiser Parts but I hope I don't need them...
