Here's a portion of the RRT

SUBJECT:

Additional Rear Axle Fluid Needed

OVERVIEW:

This bulletin involves adding an additional 19 fluid oz. of rear axle lube and a 1 fluid oz. of
friction modifier to the rear differential.

MODELS:

2011 (DS) RAM 1500 Pick-up
2011 (DX) RAM TRUCK (Mexico)

NOTE: This Service Bulletin applies to vehicles equipped with a 3.21, 3.27, 3.55, 392
or 4.10 rear axle (Sales Code DMC, DML, DMD, DMH or DMF) built before
December 11, 2010 (MDH 1211XX).

DISCUSSION:

This Service Bulletin is being released as a preventative countermeasure to address an

axle durability condition.

 

I am confused-Are all 2011 1500's built before Dec 11th included in the recall-My dealer says not?

 

If it is your build date you're looking for, it's on your driver side door jam (in case you don't know)

 

Has this issue been completely resolved for manufacture dates after December or are they considering the overfill a fix? I am ready to upgrade and the local dealer has a couple of Laramies I like but I want to be sure to get the correct bearings and know that I don't have to worry about a lube shop getting the wrong lubricant level in the rear end down the line. I've been working with geared industrial machinery for 39 years so this is an item of concern for me, I buy good stuff and keep it for a long time.

 

The recall just came out this week, it is k36. It has a new rear cover (with the hole little higher than the 2010 ) and a restrictor that gets tapped into place in the pinion drainback hole.

 

Just checked my VIN on the Dodge Canada website. No recalls for my truck, build date Feb 2011.

 

Amazing. How long have we been building low-tech differentials now, maybe 75 years, and millions of them all over the world. How do you go and screw up proven manufacturing and technology?

 

Lol, probably was "as per design" like everything else!

 

2011 Dodge Ram 1500 4x4 front (205mm HD) and rear (235mm) differentials are the source of my permanent headache...
There is not a single brand in the whole world that provides diff locks for any of them!!!
How can this be possible, I simply couldn't find a convincing answer yet...

 

Im Curious. Any of you have the Service 4wd light come on. I have a 2010 Ram. It come ons once, goes away and then re appears. Dealers dont know. I just contiue to drive like they say.
