How do I know if I need to replace my suspension?

Hey all,

The Specifics:
2nd Owner
2002 330Ci
Sport Package
Upgraded to M3 Wheels - Staggered
136,000 miles

My question is simply, how do I know if I need to replace my shocks/springs?

Handling:
- There is very little body roll.
- The ride is very rough (has been since purchased). Sometimes it seems so rough I wonder if something is worn out and needs to be replaced. But that could just be by design?
- Bushings have been replaced a couple years ago.

Anything else that would be helpful to know?

Thanks in advance!
J

Yeah assuming that they have never been changed, then 136,000 is a long time. Once you start to get a lot of squeaking and rough ride, vibration in the interior, they (shocks and or struts) are probably already shot. The springs are probably still good.

Just did mine fronts and rears with all new OEM parts associated with shocks and struts (minus the springs) and total parts cost was just over $1000. Did labor myself, ended up having the springs compressed and removed and installed on a new set of struts ($20 total) done by a Big O Tires. Tried to use the "Death Sticks" on the sport springs and they are a *itch. Kept sliding around after like several hours of trying everything. Next morning woke up and just brought all of the parts to Big O to have them swap the springs for me. Done in 20 minutes. Taking them in and out, maybe an hour per side, fronts and like an hour total for rears.

In some other threads through searching when I got mine, one thing that was brought up, was that the stock suspension doesn't usually seem to just go "bad" like other vehicles, where it's bouncing all over the highway, or rolling and swaying. But once you replace it, you'll notice quite a difference. Seems to be more gradual over time, but never seems horrible, but the replacement is apparent. That aside, with 136k, it's definitely time, unless you know for sure any of it was replaced (and what with) by a previous owner.
