Thanks to everyone for the heads up. I checked my rear axle today & it was 2 1/2 pints low. I only have 1,700 miles on my Dodge. You would think by now Dodge would have this fixed.

 

Glad you caught it. Even though you didn't mention it, I'll assume you checked your front diff. Mine was low up front too.

 

So was my transfer case and transmission.

 

My 11 1/2&quot; axle was 2qts low. Blew out ring and pinion, terrible howl. Developed at 2000 miles. That is when I posted my problem in November. Ring and pinion gears, and bearings replaced under warranty in December. American Axle Manufacturing puts the GL-5 at their factory before shipping to D-C, Dodge Assembly Plant.<br><br>I checked my NV4500 Tranny and it was plumb full of synthetic. New Venture boasts on their web site that they lube it for life. ??? ???<br><br>Still trying to resolve another drrive train problem which could be related to original low rear axle GL-5 level.<br> :'(

 

Found this on another site. It states that not to fill it up, but my manual says to fill it??<br>Forum about rear axles: click here

 

Please adhere to the fill levels described in the vehicle owner's manual or levels listed below.

9.25 Front: 1/4&quot; +/- 1/4&quot; (Total of 1/2&quot; below fill hole)
10.5 Rear: 3/4&quot; +/- 1/4&quot; (Total of l&quot; below fill hole)
11.5 Rear: 1/2&quot; +/- 1/4&quot; (Total of 3/4&quot; below Fall hole)

Still lookin for the (Total of 3/4&quot; below Fall hole). NO FALL HOLE on my Rear Diff.
