What's the typcal schedule for replacing shocks of 100S wagon? I have a 94 100S wagon with 91K of city/hway driving. Car is a bit harsh over bumps and shimmies a bit to the side in hard turns. What else should be looked at in the suspension at this time??? Car has new Dunlop tires.

Not sure when to replace shocks / struts

but things to check out, first make sure the tires are inflated correctly, and are balanced correctly.
If its harsh over the bumps, you could try inflating the front two tires by 2-4psi more than the back. It tends to smooth out the ride, by countering the weight of the engine.

Also, have your strut mounts looked at. They can get worn down, and cause squirly handling, harsher ride, etc..
If you replace all your worn mounts (Struts, engine, tranny, etc) you will feel like your driving a whole different car.

Also, any sign of the suspension going bad? Any clunking, squeeking, grinding, binding, etc when turning at slow speeds, or going over bumps?
