Symptoms of the accumulators..
I forgot to mention, before I replaced my accumulators, I replaced the rear shocks with OEM parts. The left side was leaking oil so I replaced it. A year later the car was bouncing so bad that I almost hit the ceiling when I hit a bump. Someone from this forum told me about the accumulators.
After they were replaced the car rides and handles better. I got the accumulators and the fluid from parts shop.
