I got the car in Dec. 07 and the PPI showed new tie rod ends and brakes. The car has 325,000 Kms so I expect my question is redundant, however on rough pavement I get alot of shuddering while on the highway over dips and so it gives good control, although it doesn't want to run straight and i'm correcting alot. I can't tell from the record if shocks have been changed so I expect that would be a reasonable start. What else should I be looking at? BTW how firm should the ride be?

The steering dampner runs from the frame to the tie rod, in line with the tie rod. Disconnect it at the tie rod and attempt to push it in and pull out, much like testing a regular shock absorber. If it pulls in/out easily, then replace it. Its often overlooked during chassis maintenence.It controls feedback from rutted roads back through the steering wheel.
