My 1999 Explorer SOHC 4WD (130,000 kms) has developed a leak a few motnhs back, in the front differential area, it is where the power comes from the transmission to send to the front wheels, it looks like a small leak should I fix it or will be okay as long as I top up through the hole that allows to check the fluid level.
Also what caused it? I braked violently at speed which made the vehicle shake and after that day i noticed it - which was otherwise dry.
What happens if the front differentail runs out of oil and I do not check prior to it running dry?
Thanks
