Need Help: Drivetrain Whine, Slipping in tight turns

[bentcipher]

Right! So! Uhmmm... I changed the t-case oil - no more slipping, no more shudder. I'm happy.

The old oil was filthy so I flushed it completely with a quart of fluid before filling it.

So if your truck is slipping in tight turns at all times, forward or reverse, in 2 or 4 wheel drive - REPLACE YOUR T-CASE OIL. It's easy, I did it on my lunch break.

And while at it, service your front and rear differentials!

P.S. I used Valvoline ATF fluid to fill the t-case and although it stopped the slipage/shudder the noisy whine continues. Can someone recommend a fluid that better deals with the whine?

It sounds /exactly/ like it sounds when it's in 4lo...

Hi all, long time no chat...

I was having a similar issue with the binding in turns but mine was only in very SHARP turns such as a U-turns. Well all of the sudden it started making harsh grinding noises and would barely make a 90 degree turn. I babied it to a transmission shop and had 4 technicians under the VX with stethoscopes, magnifying glasses, lights... they had no clue. Thank goodness it was the Friday before the holiday and they asked me to bring it back on Tuesday morning.

I was fearing the worst when I saw this thread, crossed my fingers and changed the transfer case oil while hoping for the best.

What a difference! Who knew something so simple could sound so bad. So the moral of the story is: Stay on top of those fluid changes!

!!!!Thanks for the information bentcipher!!!!
