we were working on a 2006 megacab hemi here lately. ever since the guy bought it, its had a power steering whine. tried replacing the pump a couple times, tried replacing the pressure line a couple times, even replaced the steering box a couple times. still has the same whine. it only whines when your not holding the wheel. as soon as you pull the wheel either way it quits.
anyone else have this or seen this before?

thanks

 

A bit of a longshot, but I have seen this work in the past. Try overfilling the pump. Maybe go up about 50% between the full mark and the filler neck.
Are you sure you have the correct dipstick?

 

is it equiped with hydroboost?

 

My wife has an 08 hemi, and the PS pump on it or the parts within are junk... we had it replaced for shuddering and making the motor bog, and it is no better...

 

So long as you're using the right fluid, Chrysler has gotten notorious for this. Most common cause I've seen is that they are real tuff to bleed. Some guys have gone as far as disconnecting the pitman arm from the drag link to ensure they get full travel while they turn it back and forth to bleed them out.

**AR 05166226AA Power Steering Fluid, ATF+4 (MS 9602)
For use in: CS, DR, DH, D1, HB, JR, KJ, LX,
LE, ND, PL, PT, RG, RS vehicles**
**AR 05142893AA Power Steering Fluid, Hydraulic System (MS
10838)
For use in: WK, WH, XK, KH vehicles**
SPECIAL TOOLS/EQUIPMENT REQUIRED:
9688 Adapter, P/S Cap
C-4207-A Vacuum Pump, Hand (or equivalent)
POWER STEERING SYSTEM BLEEDING PROCEDURE:
WARNING:The fluid level should be checked with engine off to prevent injury from
moving components.
CAUTION: **MOPAR® Power Steering Fluid +4 or ATF+4 (MS-9602) is to be used in
the power steering system of CS, DR, DH, D1, HB, JR, KJ, LX, LE, ND, PL,
PT, RG, and RS vehicles. Mopar Hydraulic Power Steering Fluid (MS
10838) is to be used in the power steering system of WK, WH, XH, and XK
vehicles. No other power steering or automatic transmission fluid is to be
used in these systems. Damage may result to the power steering pump
and system if the incorrect fluid is used. Do not overfill the power
steering reservoir.**
CAUTION: If the air is not purged from the power steering system correctly, pump
failure could result.
NOTE: If the power steering reservoir cap does not have a dipstick, there will be a
sight window on the side of the reservoir for checking fluid level.
NOTE: Be sure the vacuum tool used in the following procedure is clean and free of
any fluids.
1. Wipe the filler cap clean with a clean rag and fill the power steering reservoir to the
proper level. The dipstick should indicate COLD when the fluid is at normal ambient
temperature.
2. Tightly insert Miller Special Tool, 9688 - P/S Cap Adapter, onto the pump reservoir
(Fig. 1).

Fig. 1 VACUUM PUMP
1 - HAND VACUUM PUMP C-4207-A
2 - CLEAR HOSE FROM ADAPTER TO RESERVOIR
3 - SPECIAL TOOL - 9688
4 - VACUUM PUMP RESERVOIR
CAUTION: Failure to properly connect the vacuum pump reservoir may allow power
steering fluid to be sucked into the vacuum pump.
CAUTION: Do not run the engine while vacuum is applied to the power steering
system.
NOTE: When performing Step #3, make sure the minimum vacuum level is
maintained during the entire time period.
3. Using a hand vacuum pump, Miller Special Tool C-4207-A, with the vacuum reservoir
attached, apply 68-85 kPa (20-25 in. Hg) of vacuum to the power steering system for a
minimum of 3 minutes.
4. Slowly release the vacuum, remove the special tools and add fluid to the proper level if
necessary.
5. Repeat Step #1 through Step #4 until the fluid level no longer drops.
6. Start the engine and cycle the steering wheel from lock to lock three times.
NOTE: Do not hold the steering wheel on stops.
7. Stop the engine and check for leaks at all connections. Check for any signs of air in
the reservoir and check reservoir level. If air is present repeat the procedure if
necessary.

 

We were putting jobber hoses on at first. We put on a mopar hose, problem solved.

 

Bit of a bump to a 2 year old thread..... was the issue ever resolved?

I have a 2006 Durango 5.7 hemi with the same issue. Tried additives to the fluid, then put new ATF+4 in. Nothing seems to get rid of the noise at high rpm with the wheel straight. Slight turn and there is no noise.
