Gear oil is only at the diff. and it is in the middle/ under the engine. If you see any sort of oil at the whee it could be brake fluid. Don't drive until you find out what is wrong in it.
Since it is locking up, may be the front diff is broken?
Turns out the brakes over heated and it blew all the oil out that side CV boot thanks for all the help
Only way I could see brakes getting that hot is if the caliper was sticking, or you were riding the brakes down a 7% grade for 30 minutes lol.
