Speed sensitive under hood whine fix

[officeraamo]

I've had this under hood whine on my 2007 Dodge ram for a long time now. I figured I would just wait it out until something took a crap and then I'd replace it. The sound was speed sensitive but was not affected by turning the steering wheel so that ruled out the power steering pump. About a year ago the water pump started leaking so I replaced that, that took that out of the equation. It finally annoyed me enough that I had to do something about it. The cheapest thing for me to start with in the belt system was the tensioner pulleys. I found the upper and lower sold as a pair on eBay for $23 delivered. Easy cheap fix. The sound is completely gone. So, if you have a speed sensitive whine from under the hood of your Dodge ram pick up that doesn't change when steering, start with the tensioner pulleys.

I've had this issue and pretty much narrowed it down to these but just haven't taken the time or money to do it. Thanks for the clarification to do it tho!
