I didn't have any rattles or creaks to start with but I did have a very hard and harsh ride whenever I hit bumps or uneven surfaces. Switching out the stock shocks for Nitrons helped, but it was the combination of both a good set of shocks / springs combined with the spherical bushings that made the difference. Its expensive if you can't do this job yourself but totally worth it and the handing becomes incredibly tight with this upgrade. The bumps are not an issue anymore since the suspension does not stick or bind ( what stock bushings did) which allows the shock to fully absorb and dampen the impact as it should. It gets setup for the next bump much better since the dampening is not restricted.
