I have a 2005 1500 Ram Quad cab 4x4 5.7 Hemi. I have a vibration when turning left or right when it is warm/hot outside, I don't notice it when it is cooler temps. It feels like it comes from the rear, not sure if it is the differential or what it may be... Any help would be awesome.... Thanks in advance.

Mine was doing the same thing and changed the fluid and it is gone..I have 47300 on the OD. 1500,2006 with LSD. I did check all ear tabs on the disks washers since I seem to have bad luck with these rear ends mostly on the 2nd gen Ram. I used synthetic 85w-140 with 4 oz LSD additive it takes. It takes 2 1/3 quarts + - to do the job..use gray silicone to seal it up that stuff is the best.I do not recommend spraying any cleaner in the rear end.Cover up the ring gear when you scrap the old gasket off and take a rag to wipe out the bottom of the diff. Put the cleaner on a rag to get the oil residue of the housing.
The owners manual says 75w-140 synthetic.with 4oz additive.
Hope all helps
