Default Trouble filling Diff fluid

Just as the title says. It was warm this weekend, so I went ahead and painted my diff covers last night, and went to install them today. Install went smoothly, got the bolts on and lube locker no issue. However, I can't seem to get the oil in the diffs. the track bar is in the way of fill hole. seems like a silly issue, but damn it, now i'm stuck without a working jeep!

also, is there an easy way to figure out how much fluid to put in? specially since i have a LSD in the rear.

Autozone has a pump that screws into the bottle and a hose the goes into the fill hole. Think its like $4. It will take a while but it will get the job done

I don't mean to hijack but did you remove your covers to paint them? I want to do mine as well. Planning on doing this in the spring.

I just used rustoleum semi gloss spray paint.. It holds up ok, but i would probally use hi-heat spray paint next time as those diff covers can get pretty hot

Each aftermarket diff cover is diff, so the amount of fluid is going to vary. I just filled then until the fluid started coming out of the hole (haha, I know)...
