YEP 4WD THE FRONT DIFFERENTIAL GOING TO BE IN THE WAY HAVE TO BE LOWER.IF YOU HAD A RWD YOU CAN DROP OIL PAN WITH NO PROBLEM.
Sound like engine oil is getting hot and thinning out try a heavier grade oil like 20W50 that will tell you if the main bearing are going. Thicker oil can't go through bigger spaces as fast making the pressure stay up in hotter conditions.
