Question about 2005 Chevrolet Silverado 2500HD 2WD

Open Question

05 2500HD 4x4 PS whining

After driving 100 miles or less and the ps system is good and hot, at low rpm the power steering pump makes a whining sound as if it were low on fluid. Other sources recommended change the fluid, I did flush the system and replaced 100 percent of the PS fluid. Noticed increased brake pedal response but fluid exchange did not solve the whine. My next move is to change PS pump, before I shell out the $ for a new pump does anyone know what the PS pump pressure should be if I dead head the system?

these transmissions have three sets of planatery gears the whining you hear is simply the gears doing thier job. You have to remember the allison trans is basically the scaled down version of the heavy duty isuzu truck trans they are designed more for thier load capacity then for comfort

SOURCE: Flushing radiator

There is no drain plug on an '08 Silverado. The neck is there but it was never threaded and a plug installed. Next best thing, pull the lower hose. Really thats the answer, other than a trip to Mi$ter Goodwrench. I suppose buying the mechanics a new flat screen TV will help their economy.

Steering wheel hard to turn, what should I check for this?


Heavy steering (not caused by neglected low tyre pressures) is usually related to a problem or failure with the power steering pump system.
Items to check on the Power Steering (PS) System
1. Is the serpentine belt slipping on the power steering pump pulley because it is old and worn and needs to be replaced? If it is slipping it will likely be slipping on other pulleys also.

2. You have allowed the power steering fluid to run low and the PS pump is starved and is sucking air. Running the fluid low will damage the PS pump and the steering rack. Low fluid in the PS reservoir is normally a sign of a fluid leak in the system. A leak could be on a system hose, in the PS pump or in the steering rack.

3. The PS pump may have failed, hence cannot produce the required pressure in the PS system, and needs to be replaced.

It could be a leaking hose, and the PS fluid is dropping on the hot exhaust. Check the fluid level in the power steering reservoir. If low or dry, look for a leak.
I don't know about the rattling-better have someone look at it.

Power steering leak making loud buzzing sound more loud when turning


The power steering leak is creating bubbles in your power steering pump which gets strained more when turning, which causes it to be louder when turning. If you know where your leak is, then fix that, then try to bleed your ps system by filling up with the cap off the resevoir and turning the steering wheel max left to max left with trans fluid. if the noise is still there then your ps pump needs to be replaced along with the ps vsv located on the side of the pump.

Steering makes a whining noise - where is the fluid reservoir?


the suspect part for a power steering whine is the power steering pump, flush (very important) the system and replace the PS pump..

2004 Grand Cherokee Whine - What is the Problem


It sounds like your power steering fluid is low. When the fluid is low there will almost always be a constant growl coming from the pump. Worst case - it may be the pump itself going bad. . I own 3 Jeeps but have only had this problem on my 87 Cherokee.
Ford PS pumps are notorious for making noise as they get old, but they still seem to work ok. This may be the case with your Jeep. If the PS still works and the fluid level is normal, it may just be a matter of whether or not you can stand to listen to the noise.
