Squeak or rub type noise heard from the steering column area when turning the steering wheel at slow speeds.
The cause of this noise may be due to insufficient grease in the pinion shaft seal.
The pinion shaft seal to pinion shaft interface and lack of lubrication may generate a noise.
This noise originates in the gear but may sound like it is coming from the steering column area.
The noise may not be evident immediately after sitting and the power steering may need to be operated briefly before the noise will occur.
Tip: The intermediate shaft can be disconnected to confirm the source of the noise.
Recommendation/Instructions
Important: DO NOT replace the steering gear assembly for this condition.
Replace the steering gear housing. Also, flush the power steering system and refill with DEXRON-VI Automatic Transmission Fluid.
Note: Analysis has determined that the power steering fluid reservoir inlet hose is not required to correct this concern long term.
The DEXRON-VI fluid offers the permanent correction.
For this reason, the hose is no longer required for this repair.
The new steering gear housing kit will include either a tag or an owners manual insert that identifies the vehicle has been converted to DEXRON-VI.
If the kit includes the tag, it should be installed on the power steering reservoir filler neck and secured with the cap. If the kit includes the insert, it should be placed in the vehicle owners manual in the appropriate section.
Also, please advise the customer that their vehicle has been converted to DEXRON-VI.
Note: Due to the interface between the pinion shaft seal and the fluid, it is critical to ensure that no old fluid comes in contact with the new seal. Be sure to thoroughly flush all old fluid from the system prior to installing the new housing.
- Flush the power steering system with DEXRON-VI Automatic Transmission Fluid.Note: Do not reuse any drained power steering fluid regardless of appearance or condition.
1.1 Raise and support the vehicle until the wheels are approximately 61 cm (24 in) off the ground.
1.2 Place a large container under the vehicle in order to collect the draining fluid.
1.3 Loosen the hose clamp (1) and disconnect the power steering fluid reservoir inlet hose from the power steering fluid reservoir.
1.4 Plug the power steering fluid reservoir inlet port.
Note: This step may require 3 L (3 qt) of DEXRON-VI fluid until the draining fluid appears red.
1.5 With the key ON and the engine OFF, turn the steering wheel fully to the left and to the right while an assistant maintains the minimum fluid level in the reservoir using DEXRON®-VI Automatic Transmission Fluid. Continue until the fluid from the power steering fluid reservoir inlet hose runs red.
1.6 Remove the plug from the power steering fluid reservoir inlet port.
1.7 Connect the power steering fluid reservoir inlet hose to the reservoir and secure the hose with the clamp.
- Raise and support the vehicle.
- Remove the intermediate steering shaft bolt and separate the intermediate steering shaft from the steering gear.

19.1 Remove the steering gear solenoid valve bolts and valve.
19.2 Remove and discard the three O-ring seals.
19.3 Install the new O-ring seals provided in the kit.
19.4 Install the steering gear valve and secure with bolts.
Tighten the steering gear solenoid valve bolts to 8 N•m (71 lb in).
- Install the blue seal protector (1) provided in kit onto the steering gear pinion shaft to prevent damage to the seal when installing the housing.
- Install the new steering gear housing and bolts to the steering gear. Remove the seal protector.
Tighten the housing bolts to 21 N•m (16 lb ft).
- Connect the electrical connector to the steering gear valve solenoid, if equipped with Variable Effort Steering (RPO NV7).
- Install the power steering gear inlet and outlet hoses to the steering gear.
- Install the power steering gear inlet hose retaining plate bolt (1).
Tighten the plate bolt to 12 N•m (106 lb in).
- Install the power steering gear inlet and outlet hoses to the power steering gear inlet and outlet pipe clip.
- Install the power steering gear inlet and outlet pipe clip bolt (2).
Important: Be sure to install the transfer lines in the correct location. The longer transfer line should be assembled to the upper hole on the steering gear and the shorter line assembled to the lower hole.
- Install both transfer tubes to the steering gear. Use new O-ring seals provided in kit.
Tighten the tube nuts to 15 N•m (133 lb in).
- Install the steering gear heat shield.
- Raise the front frame to the vehicle body leaving a gap of approximately 12 mm (0.5 in).
- Install the left and right front frame reinforcement mounting bolts. The left side is shown. The right side is similar.
Tighten the bolts to 50 N•m (37 lb ft).
- Install the NEW front frame rear mounting bolts (1).
Tighten:
- Tighten the bolts to 100 N•m (74 lb ft).
- Tighten the bolts an additional 90 degrees.
- Install the NEW front frame mounting bolts (2). The left side is shown. The right side is similar.
Tighten:
- Tighten the bolts to 100 N•m (74 lb ft).
- Tighten the bolts an additional 90 degrees.
- Tighten the front frame reinforcement mounting bolts (1). The left side is shown. The right side is similar.
Tighten the bolts to 50 N•m (37 lb ft).
- Remove the adjustable jack stands from underneath the vehicle.
- Install the intermediate steering shaft to the steering gear and install the intermediate steering shaft bolt.
- Fill and bleed the power steering system. Refill with DEXRON-VI Automatic Transmission Fluid, GM P/N 88861037 (In Canada, use P/N 19264717).
- Ensure there are no power steering fluid leaks.
- Lower the vehicle.

I spoke to my dealership about this issue and they said there is nothing that can be done. There should be a recall on this issue. We can’t drive our Acadia without the radio on since the noise is so loud!
