 Subject: Transfer case whining
IP: Logged
Message:
Hi All. I've been searching through the forums and haven't found a post matching what I'm experiencing so I figured I'd post. I have a 1999 Dakota 318 Manual 4x4 with the 231 transfer case. I've been noticing some whining coming from what I think is the case. The whining is there in 2H and 4H in 3rd - 5th gear but goes away in 4L. There is no rattling or grinding, but just a loud whine. I've drained and replaced the fluid, and besides being a little dark, there were no shavings in it. From what I've read here, the front drive shaft has a CV joint on it that is known to go bad, but the 4H and 4L difference makes me think it's the case. Any ideas on what might be the problem or how to diagnose? Thanks.

i would change that front CV joint cause mine went bad and it causes a vibration and that vibration caused my aluminum transfer case to shatter

that whining could be coming from the transmission too, try changing the transmission fluid, my case wines like a mofo when in 4 no matter what. you shouldn't have to worry about your front axle greanading you don't have an aluminum housing axle. it could be an internal issue but since it quts doing it in 4lo it leads me to believe its in the transmission.

Thanks Green Dak and PB. It's about time to change the tranny fluid anyways, thanks for the suggestion. I'm also going look at the front drive shaft to see if it's on it's way out. Thanks for the replies!

Black sheep,
I did find out what what causing mine, it ended being the bearings in the rear end. To find this, I dropped the rear drive shaft and had the truck up off of the wheels. i started it up and ran it through the gears and the noise was gone. Also, with the drive shaft off, I rotated the wheels by hand and hear/felt a click, click, click noise. If those wheels are moved by hand, they should be smooth and free flowing. I ended up doing the work myself; it wasn't rocket science but did require a few trips to the tool store to get the right gear, a homemade bearing pre-load tool, and some cursing. Let me know if this ends up being your problem and you are going to tackle this yourself. I can give you some more info on what I did. Hope you find the problem.

I removed the rear drive shaft and started it up and ran it through the gears and I still have the whining noise coming from the transfer case and or transmission. I would say it is the transfer case but I'm not sure. The transmission and transfer case function great with out any sign of problems other than the whining noise. It is not very loud and almost sounds like the tires could be making alot of noise but I know it's not the tires because I removed the drive shaft and ran it through the gears and could still hear it. Thanks for your reply and I will keep this post updated if I find anything new.
