Whining sound when real cold?
When my truck sits all day and its cold out, my truck in 2WD will make a whining sound going down the road, sometimes its a grinding sound almost. Appears to be coming from the passenger side of the truck towards the front. Engaging 4x4 gets rid of the noise, and the noise will usually disappear after the truck has been running and warmed up. I've changed my ball joints recently and everything looked good and yes it had done it a time or two before hand. What causes this, and how do I fix it?

Actually I am beginning to wonder if it is. I had my vacuum lines off when I did both bolt joints hoses looked to be in great shape. My truck doesn't run rough, idle rough or none of the that. Is there anything else a motor or something it could be? I guess when it warms I'll start tracing vacuum hoses.
Ah it might be the seal on the actuator.

Its just one side that makes the noise. So its likely related to that side, and not the solenoid. If I am moving down the road however and engage my 4x4 which I think is related to the fact my ABS light is on, the other side will make a terrible grinding sound as well. I have to not be moving at all to get it to engage correctly. When my ABS worked this didn't happen. Either way as soon as this crappy weather goes away I'll be outside looking into this. Right now its 10 degrees.
