Question about 2003 Chevrolet Silverado 2500HD

2 Answers

Silverado makes weird noise at 70 mph. Mechanic said it's the transfer case and also found a leak therein - wants $400 to take it apart to find the problem or we can just replace. Not sure what to do - pay to have them take it apart and find the problem or just replace the whole thing which they say will be about $2000.00. Has 140,000 miles.

Drain the transfer case about half way and pump it full of grease, then sell it. It will hide the noise, but your transfer case is screwed if you can hear it.

It's probably the chain in the transfer case. I had mine replaced at 150,000 miles and it cost $1500.00 to do a full rebuild. And that included them removing and installing the transfer case and a new yoke for the driveshaft.( Because the play in the transfer case grooved the old one.)

Why is dodge not covering the problem that many people are having with the transfer case falling off while driving it. This happend to us while driving 70 mph it a 2500 ram 2004.

Are you sure the transfer case had gear oil in it. Its like your differential it needs gear oil. If you let it run dry it will blow apart not to mention what it will do to your transmission.

I don't think you will know whats going on until someone takes the transfer case apart. It could be the shifter stuck in mid position and it is not completely in either position.

Transfer case leak

You mean between the case halves? It is just silicon, no gasket. These are good for the pump wearing a hole in the rear housing and leaking oil. The cure for it is a new rear housing and a piece called a case saver that keeps the pump from doing it again. Taking the transfer case apart to fix it is easy, I can tell you how to do it.
