Differential Crush Washer Spit Out

[aharlan001]

Please tell me I'm overthinking this but I did some maintenance today gear oil x3 and engine oil and I noticed the crush washer for the fill and drain plugs on the rear spit out. I would not have filled the rear had I noticed in time but I did not until I went to put the plug in. I definitely won't use these amazon knock off crush washers in the future (I've used them before with no trouble) but do I need to replace the drain washer? I would really like to avoid this because collecting and re-using that fresh fluid is going to be a pain. I did not over torque the plug. I tried several washers on the fill plug. They seem a little too big to begin with and begin spitting out around 20 ft/lbs. I'm aware that it looks like it is leaking in the picture but I doubt it really is. What I am worried about is slow leaking over time causing rear end damage with the fluid being low.

best bet is to get the OEM washer. There is a very high chance that will leak. and gear oil STINKs so you dont want any leaks

Haven't used one for the diffs in 10 years, no leaks

Make sure you are using the steel washers for the diffs, not the aluminum ones for the transfer case. They look like the steel ones, but just FYI.

Also you can get a handy-pak here of OEM ones.

You won't fail to notice if you have a significant leak. If it's just weeping, you have time, lots of fluid in there and the diff isn't exactly fragile. Alot of us drive around for years with rear axle seal leaks.
