hey everyone

today i replaced the front drive shaft on my 97 explorer, switched it to 4x4 and when i turn im getting a horrible moaning sound. Im assuming that its the front differential fluid but i have no clue where the filler hole is do you have to remove the front cover or am i just not seeing it

thanks for you help

Did you ever find the filler hole? Mine has developed a leak and I would like to check the fluid level.

 

The filler plug is easy located once you take the front drivers tire off.

 

The fill plug is on the drivers side of the case about pinion level right behind the front cover. If the moan wasn't there before the shaft replacement I don't think fluid level is the problem.
