    How load is the noise? Have you noticed the driving conditions when this happens? Last one, does your Equinox have AWD?

Is the rearend blown into peices? if yes replace the whole thing. If not put it in reverse and have someone look to see if the rear driveshaft is spinning. If it is you more than likely need a ring and pinion set in the rearend. If it doesn't spin the problem is in your transmission not the rearend.

SOURCE: 1996 suburban makes grinding noise in 2 wheel drive

sounds like the clip on the rear output shaft its probably broke. do this by removing the rear driveshaft, and the tail of the transfer case, there are 4 bolts holding it in place. then grab the output shaft and see if it has any front to back movement. if so pull it all the way to the rear and you should see a groove at the front part of the shaft where the clip goes. Then you should find the pieces fo the clip in the tail housing. One person said he found the replacement clip at a local tranny shop. I am calling the dealership parts counter for a new clip for my 97 Tahoe tomorrow. Hope this helps..

You have a 4L60E whick is controled by your ECM. It sounds like you need and new transmission, the sun gear in it has failed and is the weak point on this transmission. 
When you get a new transmission have them to a corvette servo upgrade. The part is only $45.00 and the shop should know about the upgrade. It will make your truck shift a lot more firmer but last longer. 
Here is a write up http://s-series.org/component/option,com_tech_article/Itemid,/item,6/task,item/
Good luck and hope this helps

If this noise happens on wet or humid days this is natural

It sounds like the fly-wheel. If that's not it please let me know and if you can get more information that might help too. Good luck.

SOURCE: grinding noise while driving.

Possible causes:

a) a brake disc shield is too close to the disc, and it's coming into contact in the circumstances you outline

b) pebbles stuck between the disc shield and the disk

c) dried out wheel bearings

d) worn Universal Joints in the drive shafts

e) worn A/C pump

f) worn alternator

g) worn water pump

Is the noise still present above 15 miles an hour and past 1500 rpm when the clutch is disengaged (i.e. gearbox in neutral?). The answer to this question may help you to pinpoint the source. I know it's stating the obvious but the fact that you're hearing a grinding sound means it's caused by something that is moving relative to something else. Again this should help narrow down the cause.

What is it when in reverse the automatic transmission on a 1999 Camaro grinds?


Reverse is not "synchronized" forward gears are, so it does make some noise, try shifting to 2nd before engaging reverse to slow gear rotation and limit gear clash or grind.

My '96 gmc yukon makes a grinding noise in reverse and first gear. Power is fine just the noise until it shifts to second an then no noise and no problem.


first gear and/or reverse may be noisy:
Either a torrington bearing or a planetary bearing is on its way out. Trans will eventually die a loud, catastrophic death. Cheaper to rebuild now (saves further damage to hard parts), but requires R&R. It is drivable until it breaks.
Thank you for using fixya and good luck

My 2001 Chrysler Voyager shifts into neutral while driving


I doubt you going to get a code from the transmission. Im surprised that shop you have it taken to cant tell you what is the problems. If you have high miles as 100k chances are the tranny is worned and need service or replacing. Transmission rearly grind or make a grinding noise, the brakes will make the grinding noise due to the worned pad as metal rubbing on metal, have all breaks check. If the van is 5speed, yes I can see the tranny will make a grinding noise VS automatic transmission. I would take it to another shop and get another opinion or take it to the dealer which they usually charge 70-75 buck to have it diagnose. If tranny need replacing check ebay to junk yard, is lot cheaper and as good than having it rebuilt.
