Have another question for you folks. I've recently, like very recently, decided to start doing my own maintenance on my 2007 Chevy Tahoe.
Today's job was to replace the front differential fluid. The truck has 175k miles on it and I don't think the front diff oil has ever been changed. Yes, my bad, I know since I've owned it 75k of those miles.
The process started 5 days ago, but when I couldn't get the fill plug out, I started the process of soaking it with some penetrating oil for a few days, tried again, soaked it some more, and today I finally was able to break through the corrosion and get it off. I then drained the diff oil. I figured it would be low for a couple reasons. While I don't have any drops of oil on my garage floor, there is some oil splashed on the case and around the general area. In addition to that, the last few weeks I noticed a hum coming from underneath. I assumed it was the front differential.
Well, I got about 34oz out of it, so I was about a quart low. I'm curious about what damage might have occurted from it being this low. The oil that came out was black. The fill plug had, what I would say from watching youtube videos, normal metal flaking, but no metal pieces on it. It wasn't any worse than others I saw on the videos. I had the front end off the ground and rotated the wheels and noticed no rumbling, grinding, or side to side play when I tried to wiggle them.
Curious as to what damage may or may not be present. I haven't been able to drive it yet as my ECM was shipped off for a AFM Disable and I haven't got it back yet. Anything I should be looking for besides listening if the hum/whine goes away? Is 34oz of oil enough to lubricate everything it needed to? TIA
