My 2011 Ram 3500 maintenance schedule for the rear diff. is every 15,000 miles. Had that done at a local garage and added Amsoil 75-110 Severe Gear Lube and Magtec differential cover with sight glass from Geno's Garage. Problem solved!
Good call!
The 15k is if towing/severe duty service. I mis read mine I looked at the 24k kilometers. At 20k towing combined 33k when taking off from a stop I experienced grabbing when turning. That was at 20k. I drained and had fluid analyzed it was completely shot!!! at about 24k.
Since that first change I run AMZ/OIL 75-110. I just change it at 15k along with my transfer case, fuel filters, air filter and oil/filter. Could I run it longer, YES but it's cheap and easy do do all my maintenance at one time.
Bottom line the quality of the OE lube is NOT very good.
