My 2003 Ford Explorer has a noise in the differential.

[troy9181]

i have a good friend who as a 2003 ford explorer babied and it makes noise when i turn a grinding noise while turning and a whirrrring sound during accel and at speed girnding has gotten worse so i want to try to change the diff oils myself finding ams oil 75w140 was a bit of a pain, and a ford dealer had the friction mod oil but now i need to know how to fill the diifs after drainage also where is the front fill plug behind the front wheel? and if i should remove and clean the covers which from movies on youtube looks like a pain in the ass or should i just have some one qualified to do this

Welcome to this forum! I've renamed your thread, and moved it into the transmissions, transfer cases, and differentials section.

the front fill plug is on the
front - cover of the diff, rubber plug, no drain, siphon?
rear - fill and drain hole (remove the fill first to make sure you can fill it after draining).

imho-Easiest i found is go to a lube joint or such and they can siphon the old out and fill it for you. . . cost me about $15 an axle if i brought my own oil in. A lot easier then messing with the front, even though the rear is easy might as well do it while your there, plus they dispose of the old stuff.
