300TE Rear Suspension Sag

[uberwagon]

Just had my car aligned and the tech pointed out that the rear suspension is sagging on the driver's side. He suggested the accumulators (spring actuators) should be replaced. My question is could bad accumulators cause sag on one side? I will probably replace them as the ride is pretty harsh but want to know if this will fix the driver's side sag or if maybe this sag can be fixed by some other means.

Thanks,
