Transfer case issue!!

[Stack87]

So I need some help I think I'm having issues with my transfer case. I'm getting a grinding noise when accelerating in that location. Also I did put the vehicle on jack satnds the other night and ran it in gear and was wondering if all 4 wheels should turn? It is the 4x4 auto switch on dash any help I would appreciate it?

You should get a front wheel spinning and one or both of the rear wheels spinning. Consider dropping the front driveshaft and testing it that way.

OK so if I drop the front driveshaft and it goes away that would tell me it's the transfer case?

It could be an issue with the front shaft itself.

@Stack87
On stands, you MUST switch to "4X4 HIGH" before engaging "Drive". Failure to do so allows the unequal drag inherent from wheel to wheel to allow speed differences between front and rear axles, causing the Electronic Clutch, being cycled by 4X4 AUTO to go nuts.

This is, however, a perfect way to locate noise source, using a stethoscope or large screwdriver, handle pressed into ear lobe. Check the CV joint on front driveshaft. Be careful doing this! imp
