I just got my car back with new transfer case yesterday.
Drove it for maybe 2 miles and noticed a strange -metallic sound (buzz).
It is kind of quiet sound.
Comes on at different speed.
At over 50 mph it is hard to hear it because it gets loud in the car but it is there.
At lower speed it comes on and off. Sometimes it is louder than before.
You would think that there is something loose somewhere – like a loose screw in the middle of something.
Obviously I think it comes from a TC because that was the only thing dealer was working on.
When I take my foot off the gas or accelerate the sound comes on and off.
It really appears at any speed but I hear it best at around 25mph.
What do you think it may be?
What could go wrong?
Does a TC need a brake-in?

Thanks for your help guys.

 

Take it back to them. Maybe they forgot the fluid or use wrong fluid. Crap happens at the stealer**** if that's where you took it to.

 

Find out exactly what oil they put in your transfer case.

The must only use Diaqueen LSD Gear Oil. Part # 3775610.

 

OK it is me again.
Another question.
Does TC make whining noise when spinning wheels (in snow)??
I know it should not make that noise when driving but what about spinning wheels.
It is loud (whines) when I do that.
Is that normal?Or is that when it is accually trying to do its job?
Please help
This car drives me nuts.
My next post may be in "for sale" forum.
The whole story is I have about 100 miles on new TC and I hear this noise.
I did put a above recomended fluid in it only after 70 miles on whatever dealer put in.
Gears guy what do you think?

 

Take it back
