Power Steering Whine

A few months back the power steering pump was making this loud whining sound. I had it replaced and now the whine is there but different. Before it was just a constant whine and now it's a whine that seems to go with the RPM's. The noise seems to be in the same place as the pump but I'm not positive. Anyone ever have this issue in the past?

all i know is the low speed wine is something that is common with these cars. i asked the dealer about mine and he said the rack would need replaced. its not that loud and its only a low speed so i will take my chances.

Does the sound change when you turn the wheel back and forth? If not, it's probably not steering, it's probably a noisy oil pump in the tranny. If it does, it is steering. So the pump was replaced? How long ago? Sometimes it can take a bit to get the air worked out of the system, make sure the fluid level is topped off. If all those things check out, the rack is the only thing left.

It doesn't make any abnormal sounds when the wheel is turning. The sound definitely comes from on top by the pump and the other pulleys on top.

Please let us know what happens when you're able to consult your dealer, Adamstim21. I hope this issue gets resolved quickly, and feel free to direct message me if you want me to investigate anything for you in detail.

Will do. I hope it's something simple, cuz it is very annoying. I just don't know personally what makes these noises. Of course I wish I did. It would save me time and money.

Just an FYI. I had a whine about a month ago. Prior to the whine I made a turn and heard a metal popping sound on my right-front side. I originally thought it was a hub and one of the bearings decided to throw a party just like theyve done once a month. Drove a few miles and noticed a sort of whine. Attributed it at the time to the hub still.

Took it to the chevy dealer they diagnosed it as the left driver hub(I know I heard the sound on the right from inside the cabin). The replaced the left side hub and my ISS for the 3rd time. Picked my car up, and still noticed this sort of "electric, whirling, revving" sort of sound. I would hit the gas(not in park, it didn't do it in park) and it would sound like an electrical engine revving also. I called the dealer and told them and they thought I was nuts. It was so subtle and feint but it was there. I know my car, I drive it every day, you know... Anyway, He asked if I could bring it in in a few days and he would take a drive with me. I said sure.

The next morning(cold, maybe 30 degrees) I am driving to work and I'm irate. Probably have had 8-10K worth of repairs into this car in the last 9 months. Every other week it's in the shop. So yeah.... I'm driving on the highway and finally pinpoint to the fact that it has to be related to the tranny somehow. It also has gotten much louder. Neutral didn't have it at all. Only when I was in gear. Even better I would get the car up to 60 and let off of the gas and coast. I literally would go from 60-30 in the matter of seconds. It was like I was dragging something. Sort of like there was no overdrive in the vehicle. The noise was also loudest when i did this also.

Called the dealer and explained. Still thought I was nuts. Said their guys would have heard something like that, I said well they didn't. They hate me because my POS care is in there every other week getting fixed. (But I'm sure they love GM's warranty)

Took a drive with the guy that night, I explained that it sound like gear differentials/torque converter to me. He listed and said he's not sure if the IMP SS has what he believes the problem to be because it's a front-wheel drive vehicle. But said it most likely sounded like a "final drive."

Well to end an already long story.... ended up being the toque converter and "the final drive" whatever that is. I reminded him about the metal pop and said I hope it didn't break apart through my lines. He said they would look into it.

Ended up getting the entire tranny replaced because the single parts & repair outpriced a new crated one he said. The metal pop I heard did leave metal throughout the system.

Posting this in hope that someone else finds my unfortunate POS car's problem useful in case this isn't your problem. I searched and searched for two days on google and ended up finding better info on a volvo forum that described my problem to a T. Prior to, and even after the metal popping and whining, I had zero issues with the tranny. Shifted perfectly, smooth, not hard at all. Would have never guessed it really. I was leaning towards belts imo prior to research. The single biggest thing I noticed after getting back into the car after it was fixed was -- and I cannot stress this enough -- just how easy it is squeezing the gear lever and moving it from park - > drive/reverse and drive/reverse -> park is. It is 100% different feeling. Effortless. Kind of makes me wonder.

Good luck and please come back with the results.

Edit: wanted to add one thing. Ask me how many times the dealership has washed my car for me after getting it back out of the 50 times I've been to the dealer in 9 months.

Yeah, these cars are designed bad enough, but the stupid and lazy service departments make it ten times worse.

Thank you for sharing that, OHSIXSuperSport. If you have any dealer questions or service department concerns you'd like me to follow up on in the future, don't hesitate to send me a direct message!

Power steering

Just a side note on these newer power steering pumps. I had an 06 impala LTZ. I had about 16K on the car. The power steering pump started to whine. I thought based on my prior experience with older cars that the pump was bad. It was not. I changed it with a one from EBAY with 12K on it. Same thing. I purchased a new one from the dealer, same thing. Then I read the instructions on the installation. All I needed to do originally was bleed the pump. These newer ones are tempermental. I bled my new pump and it went away. Just some thoughts.

Jeff

Glad to say I traded the POS in. Car had less than 50k miles on it. Miles 25-45 GM paid around 10-12K in repairs (I don't get to see all of the silly things like gaskets, oil, fluid, shop tools fees, etc that most likely added up to probably $1000 after the literally 15+ times it was in the shop in a year and a half.)

This was the vehicle that cemented my attitude towards GM.... JUNK. Will never even think about buying another GM in my lifetime and would never allow my children as they grow up to purchase one either.

This is coming from a guy who has and who's parents have purchased nothing but Chevy, Buick, and Cadillac for the past 4 decades.

See ya later guys, GL.

:)
