Mike RietowHighly recommended 14 bolt Duramax next rear end service.
Noticeably less vibration - noise emissions. No more excessive backlash clunk, when put it in reverse.
I should have went with my gut feeling, and switched to Valvoline Syn gear oil long ago.
Noticeable difference bigtime. You can thank me later.

FootbrakeJimWhat weight on the Val Synth gear oil, 75W140?
I use their 75W90 in my race car, change it 1x/Yr, ring gear still looks perfect after 3 seasons and bearings are tight & smooth as silk.

HolytownMy 2013 just had to get the 2nd NOX sensor replaced. Got the 1st replaced November of last year......2 grand later, I get to be emissions compliant again.
I hate DEF!
