Every time I move the wheel there is a whining noise I'm assuming is linked to the power steering system on my 2006 ram 1500.

The fluid was changed 8 months ago using Mobil 1 atf4 and the level is good/ doesn't lose any.

Any thoughts on this? Cold weather maybe?

 

I've had something similar. It turned out that I needed new ball joints. Might just wana get it serviced at your local tire shop.
Off topic but did you ever find out who slashed your tires btw? I was just wondering

 

Actually now that I listen to it you might be right about the ball joints. I'm due for a front end service. Did it end up being your upper or lower ball joints?

And no I was never able to find proof of who it was, although I do know it was my neighbor (99.9%).

 

You were right..drivers side lower ball joint. I put in a grease able unit this afternoon and problem solved.

thanks man!

 

Sorry to get back so late but no problem, glad I could help out. I was pretty scared that I messed something up big time offroad but when I found that out it was such a relief lol
