Subaru: Power Steering Groan/Vibration

Tech Tip: Diagnosing Power Steering Groan/Vibration on Subaru Vehicles

A customer with a 2000-'02 Legacy sedan, wagon or Outback with a 2.5L engine may complain of an abnormal noise (groan) coming from the power steering pump and/or slight vibration in the steering wheel when turning at very low speeds.

A customer with a 2000-’02 Legacy sedan, wagon or Outback with a 2.5L engine may complain of an abnormal noise (groan) coming from the power steering pump and/or slight vibration in the steering wheel when turning at very low speeds.

The new style hose assembly was used in production starting in April 2002 with the following VINs: Legacy Sedan, 2*215560; Legacy Wagon, 2*310501; and Outback, 2*660215.

Repair Procedure:
1. Remove the bolt (A) and clamps (B) that secure the high-pressure power steering hose (see diagram).

2. Confirm that the abnormal noise and/or vibration has been reduced. If so, leave the clamps off; no further action is required.

3. If the abnormal noise and/or vibration have not been reduced, replace the high-pressure power steering hose with the updated hose, P/N 34610AE09B, and leave the clamps off.

4. If, after replacing the hose, the abnormal noise and/or vibration is still evident, replace the power steering pump.

Buick Encore Alignment Service

Alignments are key to the health of the tires and some of the advanced safety systems like automatic emergency braking and lane keeping.

The 2012-2022 Buick Encore is based on the Gamma II platform that is shared with the Chevy Trax. This has been the best-selling Buick for several years. Like a lot of modern vehicles, the alignment specs are tight with almost no adjustments built in except for toe. However, alignments are key to the health of the tires and some of the advanced safety systems like automatic emergency braking and lane keeping.
Front Suspension
The front suspension on the Encore has a single lower control arm and MacPherson struts. Some models have a suspension dampener on the front bolt of the lower control arm. The part helps to control vibration that could be transmitted to the subframe. If the caster is out of specification, look at the bushings on the lower control arm for damage. Camber can be adjusted by installing cam bolts in the lower hole of the strut mount. This should give ±1.75 degrees of adjustability. Inspection of the lower control arm is a critical part of aligning the Encore. The arm can be bent due to curb strikes and the bushings can quickly deteriorate. Also, inspect the sway bar links for any signs the ends have play.
Rear Suspension
The Encore comes in front-wheel-drive and all-wheel-drive versions. Both versions use a trailing arm beam axle. The camber and toe for the front-wheel-drive version can be adjusted with shims. Unfortunately, there are no adjustments for the all-wheel-drive version. If camber or toe are out of specification in the rear, look for a damaged wheel. If the thrust angle is out of specifications, inspect the trailing arm bushings.
