Engineering Tip #17: Miata Steering & Suspension Maintenance

Suspension and steering are often thought as something that you install at the time of the build and from that time forward only adjustments are needed; this is incomplete.

Racing conditions severely punish suspension components with constant high-G loading, bouncing off curbing, and off-track excursions.  Don’t wait to inspect the car after a component failure… Remember, it is not just about saving money – but being safe rather than sorry.

What suspension should you inspect?
•    You should inspect shocks for leaks
•    Examine control arms for bending
•    Check bushing deterioration
•    Scrutinize ball joint slop/play
•    Torque check all nuts and bolts and replace any that will no longer torque to spec. (Note: Every time a bolt is torqued, it can/does stretch. Regularly check bolts.)

What steering components should you examine?
•    Examine inner and outer tie rod ends for play, bending or damage
•    Inspect steering rack boots for tearing
•    Inspect steering rack for free movement to ensure there are not stiff spots through the range of motion
