Finally got around to doing my rear diff fluid change on my 13 Ram Hemi QC 4x4 today.
It is a LSD with 3.55 gear ratio.
Out went the factory fill at 79,000 km's (49,000 miles) and in went Pennzoil 75W-140 syn with the FCA friction modifier.
The gear oil that came out was quite dark but I have seen worse. Not a lot of silver/streaking but I was also surprised with the amount of foam/bubbles in it? I did a quick 5-7 mile drive before doing it and drained it within 5 minutes after arriving home. Is this normal to see bubbles/foaming? Not a lot but enough to notice it easily.
Hopefully tomorrow, weather and time permitting, I'll get around to doing the front?

How did the front diff fluid look? I'm getting ready to do a 2016 4Runner with about 25k on it. On our Tacoma's the first front diff fluid change has always looked pretty rough. You can see the 2010 Tacoma front diff fluid I changed at just shy of 43k in a post above.

2000 Chrysler Concorde 42LE transmission. Integrated transmission/differential uses gear oil in the diff. Out Subaru 75W-90, In 1 quart of Valvoline 75W-90 conventional gear oil. Chrysler warns not to use synthetic lubricant.
4th differential fill in the 195K miles on this car. Original fill, Valvoline 75W-90, Subaru 75W-90, current fill of Valvoline 75W-90 conventional. Don't remember what the original fill looked like upon draining, the second fill of Valvoline was kind of black when drained. The Subaru looked like new oil upon draining, with minimal metallic sheen when lighted.
