Front diff regear oil change

Got both diffs re-geared and followed break in procedure and changed rear diff oil at 500 miles. However due to sudden busy life ive only had time to put about 150 miles in 4wd. On the street ive gone about 10,000 miles since the regear and I have yet to change the oil in the front diff. Not sure if this is fine or ive messed up

 

Also trying to change the oil and check it for metal but currently dealing with a stripped drain plug that the company who regeared it must have overtorqued to 100+ftlbs
