Control Arm Strut

Print

The control arm strut, also called the radius rod or strut rod, serve to locate the lower control arm and prevent fore-and-aft movement. Except for impact damage, the rods rarely fail. The rubber bushings on each end are prone to fatigue and wear, and may need to be replaced after a few years. This part is found on all 960/S90/V90 models.

REMOVAL & INSTALLATION



See Figure 1

  1. Disconnect the negative battery cable.
  2.  
  3. Raise and safely support the vehicle on jackstands.
  4.  
  5. Loosen the rod-to-bracket bolt but don't remove it.
  6.  
  7. Remove the nut at the control arm. This is sometimes easier said than done; the control arm bolt can be very tight.
  8.  
  9. Once the front nut is loosened, the back mount may be removed and the rod placed on a workbench.
  10.  

To install:
  1. If the bushings are to be replaced, press them free of their mounts and install the new ones.
  2.  
  3. Reinstall the rod, attaching the bracket bolt first.
  4.  
  5. Make sure the front bushings seat properly in the control arm and that the front nut draws tight against its washer.
