'01 whine in TC

From : nathan w collier

Q: with the arctic temps and snow weve been getting lately ive been forced to use four wheel drive to get around anywhere. recently i have been getting a whine when the front drive is engaged. it sounds like a power steering pump sounds when you crank it at -25 degrees or one that is low on fluid and it sounds like the noise is coming from the transfer case. as engine rpm increases so does the noise. the front drive works but with the noise i cannot use it so for now im forced to work out of my 08 ram dont like working out of the new truck!. any ideas thanks nathan in montana http//concealedcarryforum.com http//inlinediesel.com .

cv joint no its coming from the transfer case. the noise gets higher pitched with engine speed even before road speed increases any. i assume based on this that it has something to do with the fluid. anybody -- nathan in montana http//concealedcarryforum.com http//1911talk.com http//hipowertalk.com http//glockcarry.com http//p7talk.com http//ppstalk.com .

no its coming from the transfer case. the noise gets higher pitched with engine speed even before road speed increases any. but nothing in the transfer case can spin up faster than the output shaft... try this while holding a constant 50mph or so switch o/d on and off. does the whine change any i assume based on this that it has something to do with the fluid. well stupid question - but have you checked the fluid level .

with the motor running and in neutral let the truck roll very slowly. does the sound become any less obvious as it rolls you may have the same issue with yours as i seem to be having with mine. but i tend to think its the bearing on the input shaft of the tranny. also it will change pitch as engine speed increases and/or decreases. -- ------------------------------------------ laszlo almasi ----cool toys ----mack daddy trailers ----ice angels with the arctic temps and snow weve been getting lately ive been forced to use four wheel drive to get around anywhere. recently i have been getting a whine when the front drive is engaged. it sounds like a power steering pump sounds when you crank it at -25 degrees or one that is low on fluid and it sounds like the noise is coming from the transfer case. as engine rpm increases so does the noise. the front drive works but with the noise i cannot use it so for now im forced to work out of my 08 ram dont like working out of the new truck!. any ideas thanks nathan in montana http//concealedcarryforum.com http//inlinediesel.com .

have you checked the fluid level not recently but the fluid was changed just a couple months ago. my shop is packed with other projects so i cant get it in right now. when i go to diagnose it ill be laying in a literal foot of snow which is why i was hoping for some feedback here first to save me some time. perhaps ill take the video camera out later and record the noise. -- nathan in montana http//concealedcarryforum.com http//1911talk.com http//hipowertalk.com http//glockcarry.com http//p7talk.com http//ppstalk.com .
