Power Steering Whine TSB 07-086
Hello to all, I had a hard time finding this so I thought I would post it.
TSB Attached, reads as follows.
Power Steering Moans or Whines
SYMPTOM
A moan or whine is heard when turning the steering
wheel when the engine is cold. There may be air
bubbles or foam in the power steering reservoir. The
noise usually goes away when the engine warms up.
PROBABLE CAUSE
Air enters the power steering pump through the inlet
joint O-ring.
CORRECTIVE ACTION
Replace the O-ring on the power steering pump inlet
joint.
PARTS INFORMATION
O-ring:
P/N 91345-RDA-A01, H/C 8811010
REQUIRED MATERIALS
Honda Genuine Power Steering Fluid:
P/N 08206-9002, H/C 3747284
(One container repairs about 12 vehicles.)
WARRANTY CLAIM INFORMATION
In warranty: The normal warranty applies.
Operation Number: 5121B5
Flat Rate Time: 0.3 hour
Failed Part: P/N 91345-PAA-A01
H/C 5430681
Defect Code: 07408
Symptom Code: 04201
Template ID: 07-086A
Skill Level: Repair Technician
Out of warranty: Any repair performed after warranty
expiration may be eligible for goodwill consideration by
the District Parts and Service Manager or your Zone
Office. You must request consideration, and get a
decision, before starting work.
REPAIR PROCEDURE
1. Remove the bolt holding the inlet joint to the power
steering pump housing.
2. Place a shop towel under the inlet joint.
3. Twist the inlet joint back and forth until it is loose,
then carefully disconnect the joint and point the
hose upward to minimize fluid loss.
4. Remove the inlet joint O-ring.
5. Apply power steering fluid to a new O-ring, and
install it on the inlet joint.
6. Install the inlet joint, and torque its bolt to 11 N.m
(8 lb-ft).
7. Top off the power steering fluid, if needed. Start the
engine, and let it idle. Confirm that the noise is
gone and that the system is operating properly.

reminds me of the TSB for the 06 civics. Had to replace a bunch of those o-rings on those powersteering pumps as well. I always made a mess doing this.

Re: Power Steering Whine TSB 07-086
After reading a number of posts I decided to try tightening the power steering inlet bolt. You need a 10mm wrench. The bolt is located under the inlet hose on the right side of the pump, behind the pulley. You may have to move the electrical cable which gets in the way of the wrench.
One I got the wrench on I lifted it and it turned about 1/16 of a turn. Started the engine and the whine went away.
