Thrust Arm Bush Failure (50mph Shimmy)

ModerateSuspension & Chassis

The front suspension relies on large rubber hydro-bushes in the thrust arms. When these leak or tear, the car develops a severe vibration through the steering wheel.

Est. Repair Cost: £150–£400
Warning Signs:

Steering wheel shake at 50–60mph, Judder through the steering when braking lightly from speed, Vague steering feel

What to Inspect:
  • Road test precisely at 50-60mph on a smooth road
  • Brake gently from 70mph and feel for steering vibration
  • Visually inspect the bushes for black fluid leaks (on original-style bushes)

The ribbon cables connecting the LCD screens to the instrument cluster and MID (radio) degrade, causing lines of pixels to disappear.

Est. Repair Cost: £100–£200
Warning Signs:

Illegible odometer or trip computer, Radio display missing text or numbers, Missing warnings in the check-control display

What to Inspect:
  • Check all displays in various lighting conditions
  • Run a cluster test (hidden menu) to see all pixels illuminated
