LOOKOUT for your BUSHES !


Suspension Diagnostics
It’s important to note that in identifying a worn suspension component, all surrounding or relative suspension components should be reviewed for contributing or affected signs of wear

Worn rubber bushings look for:
  • degraded, distorted, elongated, compressed or torn bushing
  • free play of centre sleeve in bushing
  • delamination of rubber from outer steel casing or inner steel sleeve
  • Poor wheel alignment
Key areas to inspect – control arms, leaf springs, sway bar mounts, steering idler,
steering rack mount, strut and panhard rods


Worn hydraulic bushings look for:
  • leaking fl uids from core of bush – simply run a fi nger over bush to collect any moisture
  • Poor wheel alignment
Key areas to inspect – front control arms, strut rods and rear crossmember


Worn sway bar/ stabiliser link with bushings look for:
  • Bushings have degraded, over compressed, split or even missing
  • Bent or snapped link rod
Key areas to inspect – front and rear sway bar/ stabiliser link


Worn sway bar/ stabiliser link with ball link joints:
  • Split ball link boot
  • excess compliance in joint- simply grab the sway bar, pull up & down and listen for knocking
  • Bent or snapped link rod
Key areas to inspect – front and rear sway bar/ stabiliser link


Worn spherical bushings:
  • Split spherical joint boot
  • excess compliance in joint
  • Poor wheel alignment
Key areas to inspect – control arms, strut and panhard rods


Worn ball joints:
  • Spilt ball joint boot
  • Knocking
Key areas to inspect – control arms

  1. Accidentally running over a pothole or running into a curb is jarring not only for the passengers in a vehicle, but also for the vehicle itself. The impact from a pothole, curb, road debris or other obstacle can damage a vehicle's suspension. The force from an impact can bend metal suspension parts or damage the rubber bushings found in the suspension's joints. The effect is similar to suspension parts that have worn out over time. The suspension changes the way the tires are positioned, throwing off the vehicle's alignment.
