    Standards for refreshing suspension

    If one were to replace many of the main OEM suspension wear parts, what would he be replacing, to get a factory smooth ride?

    -Control arms
    -Control arm bushings
    -Tie rods inner/outer
    -sway bar end links
    -sway bar bushings
    -springs
    -shocks


    What am I missing?

    Also, as far as the rear suspension goes, will I be okay with just doing shocks/springs?

    Subframe bushings, diff bushing and RTABs.

    If you're after a "factory smooth ride" you also might want to look at replacing your CSB and giubo.

      EDIT: Slow typing version:

      Plus-
      Strut mounts/bearings

      rear trailing arm bushes
      rear subframe bushes
      diff mount bush
      rear shock mounts


      This assumes your wheel bearings are good

        Hopefully no one is replacing their shocks/struts without these being part of the job...

              You can just replace the ball joints in the control arms instead of the whole thing, and use m3 control arm bushings.

                at a machine shop I assume? How much does this cost?

                  Where I live, major city, it does not worth the hustle, unless you have a connection of some sort.

                    what?

                    you mean it's cheaper to just buy a whole new arm?

                        An OEM arm will cost like 100$ where as some mooge ball joints will run you around 30. Just need a friend with a shop to press them in for you, so add the cost of a 6 pack to that.

                          Oh note though, if you're strapped for time or money, and your car has under 200K, you're probably fine to leave the Subframe bushings alone for now. Same goes for the rear diff, unless there is obvious cracking in the rubber. Both of those are in the little benefit for pita work category of parts.

                          Everything else mentioned should be done at the same time as the shocks, as they are highly related pieces, are easy to do at the same time, and provide good benefit.

                            That depends entirely on what shape they're in. They are likely okay but if they are shot it can cause all sorts of fun issues.

                              True. My suggestion was only to leave those out if something needed to be left out. Failed rear shock mounts can cause interesting problems too ;)
