look up into about a crush sleeve on there, I think it is already good on these trucks.
Anyways, Friday after the gym, i climbed under the truck. No leak from cover, factory fill hole, front seal(nothing on front side of housing, I did not look above drive shaft, but if it was leaking from seal, some would go down anyways), vent tube on axle or anything. I went to pull the dipstick but had crud up on top and had no towel to wipe clean so I did not do it. Did not want anything falling inside.
Again, It has 5 quarts in it, that went to the top line(max full) of dip stick, which is supposed to be even with factory fill hole. I never pulled factory fill plug either like I mentioned.
