Subject:
Steering Shudder or Vibration at Low Speed
(Replace Power Steering Cooler Line)
Models:
1998-99
Oldsmobile Intrigue with 3.8L V-6 Engine (VIN K - RPO L36)
Condition
Some customers may comment on a shudder/vibration condition while steering under low speed or stationary conditions, such as parking lot maneuvers.
A low frequency vibration may be felt in the steering wheel and body of the vehicle. In addition, this vibration may be audible in the passenger
compartment. This vibration will only occur while the steering wheel is being rotated.
Cause
This shudder may be caused by a mechanical vibration of the steering rack, tie rods and tires which is reinforced by hydraulic pressure in the power
steering system.
Correction
Replace the power steering cooler line with a shortened and relocated cooler line.
Important:
The power steering cooler line referenced in this bulletin should only be installed to correct vehicles which exhibit the above shudder/vibration
condition. The original equipment power steering cooler line, as shown in the GM Parts Catalog, should be used as a replacement for any other
concern.
Procedure
1.
Open the hood and apply fender covers.
2.
Siphon the power steering fluid from the power steering reservoir.
3.
Suitably support and raise the vehicle.
4.
Remove the power steering pressure line (lower line) from the steering gear and reposition to gain access to the power steering cooler line.
5.
Remove the power steering cooler line at the steering gear (upper line).
6.
Remove the constant tension clamp at the power steering reservoir and remove the hose of the cooler from the nipple.
7.
Disconnect the power steering cooler from the retainers along the right side cradle member and the retainer under the front air deflector.
8.
Remove the cooler line from the vehicle and discard.
Important:
The revised power steering cooler line is of a substantially different shape than the original cooler line.
