Well Its not really the 4x4 thats the problem actually..We recently got alot of snow here so I had the truck in 4x4 all morning, no problem. After driving a couple of miles on snow packed roads, however, I had trouble shifting out of four wheel. When the truck is in 4x4, there is absolutely no noise. When I shift out of 4x4 the hear almost like a clicking noise. Its like a crunching, or a rubbing. It almost sounds like when a stick or a playing card is being run against the spinning spokes of a bicycle wheel, but not exactly. Its almost like the hubs wont disengauge? I have a 03 Ram quadcab with a manual shift transfer case, and auto hubs. Hey any help is very much appreciated guys! Thanks alot!

 

How fast are you traveling when you shift? Are you using 4 HI or 4 LO?
A manual shift transfer case is a direct link to the transfer case, and the hubs are always engaged to my knowledge. If you pull it out of 4wd and into 2wd, it's out of 4wd - unlike an electronic one. The front driveshaft will just be turning freely. If you're hearing noises, it could be something else.

 

Well I the problem was shifting from four HI to two HI. I was traveling anywhere from 5-30 miles an hour when shifting. I tried putting it into neutral and four LO and then all the way back to two HI, but as long as it is in two HI it makes the noise. I tried running it in reverse for awhile while in two HI to dis engauge the hubs, as that is what I had to do with the Bronco, but it did not work. Could it be ice?

 

Sometimes it becomes like a high pitch whine too.. But its a very difficult noise to describe.

 

Hopefully someone else will chime in, but I'd check your transfer case fluid for both level and cleanliness. If you've never changed it on an '03, you are way overdue.

 

Had Royal Purple put in October 18th. Fluid should not be the problem.. Its just very strange. It will Engage, but make this very loud noise.

 

Thanks for the help though!

 

Sounds like you might have a bad hub.

 

Sounds Great. If it is a bad hub, is it okay to drive in 2 HI? I only ask because the roads are just about cleared here now, and I'd rather not have to leave it in 4 Hi until I can get into my mechanic.
