"Heavy" riding 850

I have a '93 850 GLT 2.5 20v auto saloon.

I drive it with care (she's getting on), but am becoming increasingly aware of the car's harsh ride.

She now crashes into every bump on the road and I find myself steering to avoid any road imperfection. On the last MOT the suspension was passed as OK with the exception of one of the front sway bar bushes that needed to be replaced. It's still a hard ride, but now it makes an occassional squeeling noise from the front when turning and going up the "up" ramp in the local multi storey carpark.

The ride is so harsh, I regularly go through lamp bulbs (tail & headlamp) : broken filaments due to impacts.

It's standard wheels and tyres. MOT station says shocks are OK. Any ideas ?.
