So your seals are leaking, and they need to be changed out.
Do one side at a time.
Start by ether draining the oil or tipping the car to one side to lessen the mess.
1) remove the 3/8-24 nyloc nuts these can be reused, torque= 30 ft.lbs. on install
2) use the jack holes in the side covers to remove the cover. ( these are 5/16-18 thread, blow out any sand that may be in these holes, use a side to side removal attack on the side cover so as to remove squarely.
