I'm with Dave, too. Leave as is - the ride should already be good. If dampers (shock absorbers) are past their best, then by all means replace these. (You can do a simple test by unbolting the lower end of a damper, and pulling it out to its maximum length. You should feel steady resistance when you pull, and similarly when you collapse it - steady 'thick oily' resistance all the way. Any loose spots, or hiccups, then replace the units - and do all four together.) Also, remember that the tyres are the most critical item in the suspension chain. They absorb all the sudden bumps/ridges/potholes. If tyres are ancient, replace. Also, avoid over-inflating tyres, even by 1-2 psi. An over-inflated tyre can wreck comfort. Always check pressure when tyre is cold (i.e. first thing in the morning). If car has tendency to 'wander', or be imprecise on the steering/cornering, check out the rubber suspension-pivot bearings. If back end flails about when the steering wheel is waggled, suspect under-inflated rear tyres. Buy decent tyres - eg Bridgestone, Michelin or whatever. Avoid all budget stuff. Chris
