Whining from underneath.

[wesman43]

I am no expert whatsoever, but I know something isn't right. It used to only whine like this when I had some sort of four wheel drive engaged, now it's all the time. When I accelerate between 30-45mph it has a intermittent whine. It changes pitch/dissappears when the trans down-shifts. Sometimes it happens, sometimes it doesn't. However, right before the trans shifts, it makes like several whines in rapid succession. This is worrying me because I am dumping money into this car like no other and I just want everything to be fine for once >.> Truck has 96k and it's an '05. I have checked the trans-fluid and it looks fine, and isn't low. So what do you think it could be? This is really worrying me

Is it even possible for everything to be fine at the same time?
You've checked the trans fluid, What about axle fluid levels, bearings, u-joints
"several whines in rapid succession" an actuator or a torque converter,I dunno?

I just changed front and rear diff fluids, as well as transfer case. Time to crack open the haynes manual. It's about time I greased everything anyways. And naw, everything shouldn't be fine at the same time LOL I just didn't figure I'd put THIS much into it but that's what owning a car is about. Most of it is preventative, and some is repair. Costing me like 1/2 my damn paycheck lmao. I love these trucks and they are "running deep" - into my pockets but it's worth it. Should I just have a shop look at it? Or should I not really worry about it since it doesn't happen except only 1/3 of the time?
