Deuce Transfer case case??? - Steel Soldiers::Military Vehicles Supersite

sailor2000 · 09-29-2007, 14:05

Well... drove the Deuce today without my earplugs... and think my transfer case MUST be going... sounds good up to about 35 mph in 5th gear... then a LOUD grinding / whining / screaming noise starts... sounds like from under the seat... push in the clutch ( at 40+ mph) ... same noise... put tranny in neutral ( at 40+ mph).l.. same noise... put transfer case in neutral ( at 40+ mph).. same noise... and I just changed my u joints...

Should I bother draining the case and filling with Lucas? Just changed the transfer case fluid...

Can anyone suggest a good source for a good take-out transfer case???

pull the magnetic drain plugs on both and look for signs of damage. sounds like no or low oil

Drained and refilled both tranny and transfer case a few weeks ago (last time I drove it)... almost no metal on the transfer case plug magnet... tranny had no magnet... lots of silver metal came from one of them... saw it when i drained the 5 gal bucket I drained both into... but both were full.. and no signs of leaks...

if the truck has been driven fast, second gear could have seized to the trans main shaft. once that happens it's all down hill from there and will only get worse. it's a simple matter to pull the trans top cover and see if second gear has turned blue from heat...........

"put tranny in neutral ( at 40+ mph).l.. same noise... put transfer case in neutral ( at 40+ mph).. same noise..."

noise persists with tranny not turning....

Check your Ebrake for sympathetic vibration...

Clutch in, engine at idle, tranny in neutral, transfer case in neutral, rolling at 40 mph... no change in thenoise from heck except now it seems much louder cause there is almost no engine noise... and teh trans may be turning but not very fast... certainly much slower than when the lutch was enganged and and teh engine was turning 1900 rpm...

It's common / normal for the t-case to be noisy... Out of the 6 I've encountered, I have yet to hear a quiet one! Mine has a distinctive whine to it, especially when decelerating. Are you certain it has gotten louder lately, or did you simply not hear it before?

I'd certainly check / change the oil as suggested, but as long as it's not popping out of gear... run it.
