4wd struts

struts struts

Struts are basically another shock absorber, so they need attention.

Put simply, struts are an additional shock absorber, so shock engineers give a lot of focus to the strut length and strut travel when designing shocks. If they make a mistake, the strut could "top out" before bump stops engage, leading to bending or failure.

Getting under the hood in strut design.

A strut uses a wishbone, which gives a point to affix the hub carrier or axle... this lower arm system gives wheel location. The upper section of the hub carrier is fixed to the underside of the outer strut, enabling a sliding motion which extends upwards to a fixture in the vehicle shell. The line from the strut's top mount to the bottom ball joint on the control arm gives steering axis guidance.

If the vehicle has an anti-roll bar or swaybar, it's connected by a ball-jointed rod to the spring-damper, or by a ball or jointed rod running to the wishbone.

The pros of struts

  • Vehicles with struts in the front crash area are simpler to engineer and pass more safety crash tests than vehicles with struts over a double wishbone suspension.
  • The simple design means there are fewer joints in the suspension to avoid degradation and the poor handling that results.
  • Inverted monotube struts give additional strength in the front suspension.
  • Struts move more efficiently than other types of front suspension.

The cons of struts

  • It's not possible to achieve vertical wheel movement without experiencing camber angle change or sideways movement.
  • Struts overall do not give the same standard of handling as a double wishbone or multi-link suspension.
  • If your vehicle's cabin height is adjustable, struts are a no-go due to the camber changes built into the design.
  • Drive experience is negatively affected due to the shock absorber having pretty much identical vertical motion as the wheel.
  • A standard single pivot strut normally has positive scrub on the middle of the steering axis, which negatively affects steering.
