Low diff fluid

so.. i changed my rear diff fluid a month or so ago, also replacing the diff cover for one with a drain/fill plug. I noticed it's been leakin from the drain plug, but of course put off doing anything about it until today. basically to solve the problem I put some teflon tape on the threads and resealed it.

but the question is, i guess it turns out I had leaked more than I thought. I bought a quart of gear oil, and used the whole bottle as well as another quart I had in the garage. Now I know I lost some when I pulled the plug, but I put my finger over it and had my dad prepare the plug and I put it back in. I certainly didn't let even half a quart out.

but lets say I was a quart and a half low, which seems about right. Should I expect any lasting damage? I may have driven 500-1000 miles with the leak but im not sure.

time for a l/s?

At a quart and a half low I would worry more about the axle bearings .
The ring and pinion will probably be all right.

well, there are two different bearings on the rear drivetrain, outer bearings and carrier bearings. if you're not hearing whining/humming you'll be fine. the carrier bearings need to be pressed on, i've never done outers so idk about those.


EDIT

I forgot about the pinion bearings lol
