Took the truck into the dealer this morning to find out what the noise is thats coming from the rear. I told them if they couldn't hear anything I wanted them to open up the case and check it anyway. They called me about 2 hours later and said it was full of shavings and two of the gears were badly worn. The whole thing needs to be replaced. Truck is less then a year old and has 11,000 miles on it. Good thing it's under warranty. They showed me the order sheet for the parts and the whole job was figured at $3200.00!!!! I sense a bit of inflation there but at least I don't have to pay for it. Hope the next one last a bit longer.

 

Warranty parts is cost times 40%.Labor is flat rate time at their approved D.C. rate.Nothing the dealer can do to alter eaither.

 

Sounds like you got one that was about 1-2 qts low on fluid when shipped. In 03 alot of them were shipped that way.

 

With you pulling that triple, you need to be sure and run 75W-140 lube in that rear end.

 

Where does it say to run 75-140 every thing that I read for the Dodge says 75-90 but I have a friend with a Dmax (same diff) and he says that they advise 75-140 ( all full synthetic)

For towing, I use 75W-140 lube in the rear-end. I far as I know, Dodge is the only manufacturer using AAM that specifies 75W-90. I think it has been reported by guys who contacted AAM, that even AAM recommends 75W-140.

You can take your pick.

 

I didn't hear anything about this before. I know my manual says 75-90 syn. but I will definately check on it before they do the changeout. I called them today and they still don't have the parts in. They were supposed to be in on Wednesday but, no show. I'm a little afraid to drive the thing knowing the rear is bad. They told me I could drive it but "don't push it" whatever that means. I may have to drive it this weekend. Hope it doesn't totally give out on me. I hate when things are "broke".

 

I have the same problem with mine 04.5 w/ 84000 miles plus i just found out the the 100000 mile warranty only covers the engine now the rear and transmission is only covered till 70000 miles i guess that ill do it myself

 

Yeah, only 70,000 miles or 7 yrs. I'm wondering what they'll do with a warranty on the new rear end their putting in. Do I get a new 70,000 mile warranty on that one or do I get the proverbial "stick" on it? Guess I'll find out when they do it next week.
hauliday, how'd you put 84,000 miles on an 04.5 already???

 

The 5-star dealer in Austin will only use 75W140 (rear only). They said too many failures with 75W90. The GM's diesel also blew the axle, be the got it fixed quickly . My last change I used 140 in back and 90 in front.

You get neither.... you get your truck repaired, and it's still covered for the remainder of your original warranty... just as if nothing had gone wrong in the first place.

 

but this says a lot for dmc the only thing that has a 100000 mile warranty is the cummins engine that is bought from cummins without warranty everything else has a lot less warranty i guess that they are not that confindent in their own product if they dont belive in it why should i

 

2006 is only 3/36 on drivetrain.Be thankful you had 7/70 cause its gone now.But I DO remember when ALL was 12/12500! It wasn't THAT long ago.

 

This TSB deals with differential fluid levels, but it does specify 75W-140 for rear axles. My DC service manual specifies 75W-90.

Mike, the TSB on Fritz's web page is wrong. People on TDR are trying to get a hold of him to correct it. The TSB specifically states 75W-90.

Here's the link at TDR that also shows a copy of the TSB printed at a dealer last week:
