How To Check The Used Suspension?

[Alfred Y]

Hi all

Need some advices for checking the second hand suspension. I have buy a set of HKS suspension for a ER34 GTT (2 door)but I don't know how to do some basic check for the coilover. Can you guys give me some idea or advice? Thank you for everyone help!!

Take the hats and springs off and put the shocks on a shock dyno.

Check the dampers (shocks) for any signs of leaking or visible wear on the shaft. Turn the shock upside down and use your weight to compress it. Each damper should take about the same amount of consistent effort to compress. They should then return by themselves to full extension fairly quickly. If some take a lot longer (or don't come back) they could be worn out. Make sure any damper adjustments are set to zero when you do this check. A shock dyno is of course much better but not free.
