This is really strange....its a lengthy explanation, but maybe you can help
OK, I started the tuck up this morning to go to work, really cold and snowing a little today, I think it was around 2* at my house. Let it warm up for probably 5 mins and pulled out of the driveway
As I head down my road, I hear what sounds like a small rodent trapped somewhere behind my glovebox, or in the passenger side dash, scurrying around in there and trying to escape. A little dull bumping sound accompanies by a higher pitched screeching, scurrying noise...a familiar sound to me, lol
I've had mountain packrats build nests in AC vents and engine block of past vehicles a few times before, so I immediately think there must be something up in my engine bay trying to get out, would make sense given how cold its been the last few days. I pull over, pop the hood....nothing, engine bay is completely clean. I looked under the passenger side wheel well, at cv boots and all linkages, everything looks fine.
What's more, the noise stops when I stop the truck. I reved the engine while still stopped, no noise.
I start moving again, the noise starts up again, I turn off the blower fan, the noise continues. When I accelerate, the noise DOES NOT change in frequency or pitch. It's totally irregular (like a small cat trapped in a slate-lined shoe box trying to get out)
I had to get to work, so I put up with it in the way to the ski basin. It was around 0* this morning in the parking lot. I figured, if it is a little animal stuck up in there, he's gonna get out over the course of the day or freeze to death.
I get back to the truck this afternoon, still snowing and cold as hell, pull out of the lot and the noise it still there...allll the way home. I thought maybe its a 4-wheel drive linkage, switched to 2-wheel drive, still there. Driving up my road, I thought I could here a heavy thud coming from the right front wheel well in addition to the noise, but need to confirm this
Checked my cabin filter for crap or any clues and found nothing but a few leaves
The truck is driving just fine in handling and all
