Need help possibly dumb question **Rear end related**
I couple of months back I got Detroit Trutracs and 4:10 gears installed front and rear. A couple of days ago I noticed what looked like gear oil leaking from my rear end. The leak isn't bad, small drip when parked for a day or so. I am at my brother's home in VA and decided to check the level to make sure it wasn't low before heading home. I have the Teraflex diff covers, that have to 2 fill holes. I know the lower one is for normal use and the upper is for axles with high pinion angles. Anyway I loosened the lower hole and when I removed it oil flowed oil like it was filled to the top hole. The shop that did the work for me is more of a performance shop than a Jeep shop. So I know the work was done right, they may have just not known about the fill level. So my question is, how bad is it to run with more oil than needed in the rear end? I'd rather wait until I got home, to drain and refill my rear end.
