Power Steering Shudder or Vibration at Idle (Replace Power Steering Inlet (Pressure) Hose)

This bulletin is being revised to add 2007 model year. Please discard Corporate Bulletin Number 06-03-32-012A (Section 02 -- Steering).

Some customers may comment on a shudder/vibration while rotating the steering wheel at idle. This vibration can be very minor to where it is only felt in the steering wheel or major enough to notice a slight shake in the interior components. Rougher road surfaces can increase the intensity as it increases the drag against the wheels as they attempt to turn. Slightly raising the engine idle should eliminate the vibration.

At idle, turning the wheels causes the steering pressures to raise high enough to cause a load on the engine. The load is great enough to cause the idle to become rough and it can be felt in the vehicle.

Replace the power steering inlet (pressure) hose with a revised hose. Refer to the pictures below for new hose routing.

Vehicles with FE1 and FE2 Suspension

For vehicles with either FE1 or FE2 suspension, a retaining clip, P/N 88967174, is also required. After installing the new hose (1), attach the clip (2) to the hose just before the crimp. Secure the other end of the clip to the existing power steering return line.

Vehicles FE3 and FE4 Suspension

For vehicles with either FE3 or FE4 suspension, a screw, P/N 11609268, is also required. After installing the new hose (1), secure the clip (2) to the front crossmember with the screw.

Tighten
Tighten the screw to 27 N·m(20 lb ft).
